ARLIS Alaska Resources Library &Information Services Anchorage,Alaska w W -....J 01 01 ooo ,J::o. ,J::o. Nenen 01 Supplement EXPLANATION OF SUPPLEMENT The Access Planning Study was published in January of 1982.It contained a detailed discussion and cost estimate for eleven different proposed access routes to the Susitna Hydroelectric Project.In March of 1982 the Susitna Hydroelectric Feasibility Report was presented by the Alas ka Power Authority to the publ ic resou rce agencies and organizations.The report recommended an access plan which for reasons of project schedule,would have necessitated the construction of a pioneer road prior to the FERC license being issued.The construction of a pioneer road, however,was considered unacceptable by the resource agencies and the plan was discarded.Consequently a further study was initiated in which,the evaluation criteria were refined and an additional seven alternative plans developed.One of the main issues that affected the selection and development process was the elimination of any pre-license construction.I n order to meet the overall project scheduling requirements this constraint makes it necessary to secure initial access to the Watana damsite within one year of the FERC license being issued.Amongst the other important issues considered was the desire of Native organizations to have access to thei r lands expecially those to the south of the Susitna River,and the objective of minimizing environmental impacts. Subsequent to the Access Planning Study of January 1982 being published the locations of the construction camps were finalized; the Watana camp being north of the Susitna River and the Devil Canyon Camp to the south.The change in camp location slightly modified the lengths of the road segments,but considering the samll difference,Plans One th rough Eleven were not revised. r35/a2 i ARLIS Alaska Resources Library &InfonnatlOn Services Anchorage.Alaska Supplement Throughout the studies conducted subsequent to the Feasibility Report of March 1982 numerous comments have been received from interested agencies,groups and individuals.These include State resource agencies,environmental groups,local communities,Native organizations,The Alaska Power Authority and Acres American I nco together with their specialist subconsultants.As a result of this comment and exchange of information,the seven new access plan represent a more coordinated compromise among the interested groups. The new plans,for the most part,follow segments·discussed in the original report.This supplement covers the new plans by supplementing the original report where needed.The major items found in this supplement are: 1.Additional segments needed for new plans discussed (Chapter Nine). 2.New plans discussed (Chapter Ten). 3.Segment,Terrain Unit,and Environmental Concerns maps in Appendices updated to show new routes. 4.Cost estimates generated for new plans (Appendix F). 5.Plan Eleven has been revised to include a low level crossing at Devil Canyon for access to the camp on the south side.It is now Plan 11 R. I n order not to change the page numbering of the enti re report, the following numbering policy has been used: r35/a3 ii Supplement 1.Where a figure or table is revised,the page number is reused. 2. 3. r35/a4 Where a figu re,table,or text is added at the end of the chapter,the page numbering is sequential. Where a figu re,table,or text is added into the middle of a chapter,the page number of the immediately preceeding page,plus a letter are used as the new page number.For example if three new pages of text are to be inserted between Pages 10-49 and 10-50 of the original report,the three new pages will be labeled 10-49A,10-49B,and 1O-49C. iii Supplement ALASKA POWER AUTHORITY SUSITNA HYDROELECTRIC PROJECT ACCESS PLANNING STUDY SUPPLEMENT TABLE OF CONTENTS LIST OF TABLES LIST OF FIGURES 1 -INTRODUCTION - no change 2 -SUMMARY 2. 7 Alter-native Segments -Revised Figure 2.1 2.8 Alternate Access Plans -Supplement 3 -SCOPE OF WORK - no change 4 -PREVIOUS STUDIES - no change 5 -PROJECT DESIGN - no change 6 -PROJECT SCHEDULE - no change 7 -LOGISTICS REQUIREMENTS - no change 8 -ACCESS ROUTE DESIGN PARAMETERS - no change 9 -CORRIDOR SELECTION 9.1 Discussion of Alternate Segments -Supplement 9.4 Corridor Summa ry -Supplement 10 -ACCESS PLAN 10.1 Supply Sources &Shipping Options -Table Supplements 10.4 Access Plans -Revised Figure 10.5 Access Plans -Revised Figure 10.8 Access Plans -Supplemental text &figu res 11 -CONCLUSIONS &RECOMMENDATIONS - no change r35/a5 iv vi vii 2-5 2-9A 9-16A 9-60 1O-7A 10-27 10-37 10-47 Supplement TABLE OF CONTENTS (Continued) 12 -APPENDICES A.Preliminary Design Development -no change B.Proposed Alternative Segments -revised B-2 C.Alternative Comparison -Grade,Cu rvatu re &Distance - no change D.Terrain Unit Mapping -Supplement &Revisions D.3 Terrain Unit Descriptions -Supplement 0.9 Terrain Unit Maps -Supplement D-9A 0-45 E.Environmental Concerns -no change Borrow Pits -Revised F.

Plan 11R supercedes Plan 11.Plan 11R serves the enti re project from the Denali Highway.No access is provided at Gold Creek. Supplies are shipped by rail to a railhead at Cantwell,then trucked to Watana via the Denali Highway,then on to Devil Canyon along the north side.Access to the South side of the damsite is via a low level crossing similar to the one found in Plan 5.This plan has the advantage of a low risk of schedule delay.The longer haul,however,makes this route the most expensive from a logistics standpoint. Plans 12-18 These plans use modifications of the 3 basic corridor routes used in Plans 1-11. Plan 12 is an all road,north side route that avoids the undesirable Portage Creek traverse by crossing at the mouth of Portage Creek.A low level crossing of the Susitna river is included at Devil Canyon.The road is served by railhead from Hu rricane. The disadvantage of this plan is the major bridge and associated .schedule delay at Portage Creek. Plan 13 is all road,with direct access from the Alaska Railroad and Parks Highway at Hurricane,to the Watana Damsite,via a pass near the upper end of Portage Creek.A branch road serves the Devil Canyon Damsite,crossing the Susitan River near Portage Creek. r35/a12 2-9A Supplement Plan 14 is a combination of road and rail.Rail is extended from Gold Creek north to a railhead on a terrace,on the Susitna River. From here,road continues to both damsites on the south side of the Susitna river,crossing to the north side near Fog Creek. Access to the Parks Highway is provided by a road spur from the railhead north to Hurricane. Plan 15 is the same as Plan 14,but deletes the road link to the Parks Highway.This lowers the construction cost and effectively eliminates public access. Plan 16 consists of a railhead at Gold Creek,road to Devil Canyon,road from Devil Canyon to Watana,'and a public access road from Hurricane to Devil Canyon.The road from Devil Canyon to Watana is on the south side to Fog Creek,then crosses the Susitna to join the camp on the north side. Plan 17 is similar Plan 6,except that,instead of a service road on the north side,this plan has a service road that is on the south side between Devil Canyon and Fog Creek,then crosses to the northside to reach Watana.As with Plan 6,Devil Canyon is served by rail and Watana by road from the Denali Highway. Railheads are located at both Devil Canyon and Cantwell. Plan 17A is a slight modification of Plan 17.From Fog Creek to Watana Dam,the road stays on the south side of the river. Plan 18 is another modification of Plan 6. It includes rail access from Gold Creek to Devil Canyon,road access from the Denali Highway to Watana,and a service road between the dams on the north side.Plan 18 differs from Plan 6 in that Devil Canyon is crossed by a high level bridge,and the alignment has been improved. r35/a13 2-9B Supplement r35/a14 CORRIDOR SELECTION Deiscussion of Alternate Segments Supplement Supplement (fa)Segment l-G (i)Description Segment l-G is an alternate to a portion of l-A from the Parks Highway to Chulitna Pass.Unlike segments l-A and l-F,this segment avoids Denali State Park lands and the recently su rveyed I ndian River Subdivision.The segment passes Chulitna Butte on the east side,follows the base of the mountains,and joins the highway and railroad at Hurricane.See Figure 9.2A This segment is six miles long. (ii)Line and Grade This segment conforms with the preferred design parameters. Though longer than the portion of l-A it replaces,the line and grade are comparable. (iii)Drainage Features A number of small drainages are crossed on this segment. All can be easily crossed with culverts except Granite Creek,which may require a pipe arch or small bridge. (tv)Bridges No bridges will be required other than the possible short span at Granite Creek,just east of the Hurricane Siding. r35/a15 9-16A Supplement (v)Soils By traversing the base of the mountains east of Chulitna Butte,this segment avoids the extensive organics encountered in l-A.Terrain unit mapping is not yet available in this area,however,the steeper slope and better drainage definition would suggest more manageable soils. (vi)Envi ronmental Concerns A final analysis of environmental impacts for this segment have not yet been received.The segment does alleviate the problems created by l-A.Segment l-G will avoid the wetlands encountered in l-A,ci rcumnavigate the existing cabins in Chulitna Pass,and away from the State lands that have been designated Denali State Park or Indian River Subdivision. (vii)Segment Suitability Segment l-G appears to be a superior choice to the portion of Segment l-A in the Chulitna Pass area.This cannot be confirmed,however,until aerial photography,terrain unit maps,and environmental maps are generated. (fb)Segment l-H (i)Description r35/a16 9-16B ;-,\«>t. ~..._.-.........,..-.-,;-.:....----- " ")°2 II: D D-II: II:o U CD CD W U U C c( 2..-CD :::J CD .....-~ co II I ~ ~ 2w ~ CIw UJ .....-s cD II CI ~ ~ 2w ~ CIw UJ head of Portage Valley to The line shortens the haul not provide access to Devil is six miles in length.See Supplement This segment joins l-A at the l-A/l-B in Devil Creek Valley. to Watana Damsite,but does Canyon Damsite.The segment Figure 9.2A. (ii)Line and Grade Grades will be in excess of the desired parameters.An 8% grade wi II be needed for one to two miles. (iii)Drainage Features The segment traverses a steep slope above a tributary of Portage Creek.Care must be taken to control side hill erosion as Portage Creek is an anadromous stream and the tributary paralleled may also be.No other significant drainages are encountered. (iv)Bridges Portage Creek will be crossed just upstream of the crossing anticipated for 1-A.The same class of bridge -approx- imately 200 feet long with two or th ree spans -should be s uffi ci ent. (v)Soils This segment crosses frozen basal till in the relatively flat r35/a17 9-16D Supplement Portage Creek Valley,colluvium over bedrock and exposed bedrock along the steep side slopes of the Portage Creek tributary,and frozen basal till along the gentler drainage into Devil Creek.Problems with erosion and thaw settlement will be similar to those encountered in Portage Valley on 1-A. (vi)Environmental Concerns The major envi ronmental impact anticipated is on the possibly anadromous tributary of Portage Creek that the route will parallel. By shortening the route to Watana Damsite and removing the loop of road that serves Devil Canyon Damsite,this segment alleviates several major en vi ronmental concerns.There would be less impact on Portage Creek because only one side of the valley would be traversed.The valley is a fu r bearer habitat and salmon spawning area.Also avoided is the potential raptor habitat in the Devil Canyon and Portage Creek confluence,and the fur bearer habitat and lodge at High Lake. (vii)Segment Suitability This segment's suitability is dependent on several criteria. The grade is above the desireable 6%,but only for a short distance.When joined with 1-A,Devil Canyon is bypassed, which will necessitate a separate spur road be built for the Devil Cayon Dam Construction and access.The original r35/a18 9-16E , Supplement Segment l-A traversed both sides of Portage Creek,which was considered to be an unsuitably high environmental impact.By limiting the traverse to only one side,the combination of Segments 'l-A and l-H becomes suitable. r35/a19 9-16F Supplement (ua)Segment 2-Q (j)Description This segment joins 2-1 to 2-B.Presently,2-1 ends at Devil Canyon and 2-B starts there.Segment 2-Q would start on 2-1 about 2 miles before the damsite,traverse Chechako Creek and its major tributary at their upstream reaches,and join 2-B about four miles southeast of the damsite.See Figure 9.8A. This segment is nine miles long. (ll)Line and Grade This segment substitutes a longer route,with maximum grades and minimum radius curves for the major bridges required on 2-B.By starting south several miles west of Devil Canyon Damsite,the unacceptably high grades found in 2-B can be avoided. (iii)Drainage Features As with 2-B,the alignment is on high ground and avoids most drainage conflicts. r35/a20 .. I!• .~..~; -,".,.

(v)Soils The segment traverse colluvium over bedrock and exposed bedrock.Some patches of solifluction are in the vicinity, but can be avoided.No significant probelms are foreseen. (vi)Environmental Concerns This segment may enter into the caribou wintering areas at the upper reaches of Chechako Creek.No other significant concerns have been noted.When used in conjunction with. 2-B,as a substitute for 2-G,a raptor nesting area is avoided. (vii)Segment Suitability This segment combined with the east part of Segment 2-B, appears to be equally as suitable as Segment 2-G.Though it lengthens the total mileage to Watana Damsite,it eliminates the problems associated with the high bridges at Chechako Creek and neighboring gorges,extensive rock excavation, and possible construction delays. r35/a21 9-46C Supplement (wa)Segment 2- RRR (i)Description This segment is a seven mile spur of railroad that leaves the existing tracks at Gold Creek,traverses the bluffs on the south side of the Susitna River,and ends in a railhead on a flat terrace on the south ban k of the S usitna River.See Figure 9.10A (Il)Line and Grades By sidehill cutting into the Susitna River bluffs,the railroad remains at a low elevation with a relatively flat grade. Minimum radius curves will be needed to conform to the bluff as much as possible. (iii)Drainage Features Gold Creek and several minor unnamed drainages can be crossed with cu Iverts. t (iv)Bridges No bridges are required on this segment. (v)Soils The Susitna River bluffs are composed of frozen basal till, r35/a22 9-52A " ..,"" ••-, i ;I •Q 'W ,:,'.:',>~ •,-Q, 'W "';g: ",1_)4,-....~_ :t't"J \*"""-,,-~----\;,,,.~,;...-~.:.:.~..~...,....: >, . ., ~v~'~\",~. , ,- IE 0 D-IE IE 0 ixi CII U II) I'.'a)'-UJ ~ ";'-UJ "W II - ,~,U IE U IE ('.':C IE \'."lU.J. ~:' .~~:~~C .. .'-;~2 2 ;-c'.,.,..W J,j'-~UJ CJ:::J w OJ VI, ti ~ Supplement which has a relatively low slope stability.Bin walls or other soil reinforcement may be needed.The terrace and flood plain soils encountered in the beginning and end of the segment should pose no special problems. (vi)Environmental Concerns Both 2-RR and 2-1 parallel this segment.No environmental conflicts were found when reviewing them. (vii)Segment Suitability This segment of railroad would be suitable to use in conjunction with a road that continues on to Devil Canyon (such as 2-1).It effectively eliminates all public access from the Gold Creek vicinity.It also precludes the use of segments 2L,2H and 2K due to conflicting grades. (wb)Segment 2S (i)Description This segment connects segment 2A in the Stephan Lake vicinity with Segment lC by crossing the Susitna River. See Figure 9.10B.The segment is seven miles long. (ii)Line and Grade Maximum grades will be needed on both the north and south r35/a23 9-52C Supplement banks of the Susitna River.The banks lie at 50 to 100% cross slopes,with exposed bedrock in some places on the south bank. (iii)Drainage Features On the south side of Susitna River,several small drainages are crossed for which culverts should be adquate. (iv)Bridges The Susitna River bridge will be a major high level span, with approximately 600 feet of steel truss and 2600 feet of plate girder,and over 100 feet above the present water surface.The height is necessary in order to span the future Devil Canyon Reservoir.During initial road construction,there would be sufficient room to construct a road to the bottom of the valley for a temporary low level crossing or ferry.This would speed bridge construction and avoid access delays to the Watana Damsite. (v)Soils The segment is largely on frozen basal till,similar to those discussed in other sections of this report. (vi)Environmental Concerns This area has not been studied in detail from an environ- r35/a24 9-52D Supplement mental standpoint.Previous overviews of the area did not reveal any conflicts. (vii)Segment Suitability Segment l-C has been deemed unsuitable for construction, alignment,and envi ronmental reasons .However,the small piece that joins Segment 2-S to Watana Dam appears satisfactory.Segment 2-S itself is within acceptable design parameters and is deemed suitable for further consideration. (we)Segment 2-T (i)Description Segment 2-T connects 1-A just east of I ndian River with Segment 2-1.Included in this segment is a major bridge across the Susitna River.The segment is seven miles long. See Figure 9.10B. (ii)Line and Grade The north bluff of the Susitna River will have to be side hill traversed at a maximum grade.The rest of the segment is made up of milder grades and few curves. (iii)Drainage Features Only minor drainages are crossed,which can be suitably r35/a25 9-52E Supplement crossed with culverts. (tv)Bridges The bridge across the Susitna River will be similar to the one anticipated in 2-E,a 2480-foot,orthotropic steel structure with approximately twelve spans. (v)Soils This segment travels across frozen basal till interspersed with patches of organics.The frozen basal till should not be a significant problem over the majority of the route,since the cross slope is slight.The potential for erosion and slope failure will be as high on the Susitna River north bluff,as it is on the south bluff (see Segment 2-R,2-1 and 2-RRR) (vi)Environmental Concerns A detailed study was made of the environmental concerns in this area has not yet been completed.If this segment is used as a substitute for 2L or 2E,the major impact of road access to the Indian River Remote Parcel sites would be removed. (vii)Segment Suitability This segment is suitable for roadway construction and r35/a26 9-52F Supplement compares favorably with Segment 2-L.It's attribute is the circumvention of the Indian Pa rcel Sites. (wd)Segment 2-U (i)Description major positive River Remote Segment 2-U shortens the 1-A segment by eliminating the loop up Portage Creek.Instead,the segment crosses Portage Creek at its confluence with the Susitna River,then rejoins 1-A above Devil Canyon Damsite.See Figure 9.10B. This segment is six miles long. (ll)Line and Grade The portion of this segment just before and after the Portage Creek crossing has to traverse steep (50%or higher) sidehills,but all curves and grades are within the design criteria. (iii)Drainage Features The major drainage -Portage Creek - will be crossed with a bridge.Of the other more minor drainages,one that drains a swampy area will be difficult as the entire valley that contains it is lined with organics.This and other drainages should be possible to cross with culverts.(iv)Bridges r35/a27 9-52G Supplement A major bridge is required across Portage Creek.It will be 1100 feet long,and cable stayed. (v)Soils The segment goes th rough several unavoidable areas of organics.The rest of the segment is on frozen basal till with some colluvium and exposed bedrock at the Portage Creek crossing.Construction will be similar to other areas with these materials. (vi)Environmental Concerns This segment deletes the long "traverse up and down Portage. Creek,thus avoiding impacts to salmon spawning areas ,fur bearing habitat and a mining claim.The potential raptor nesting area,however,is still impacted.Also subject to possible impact is a historical site at the mouth of Portage Creek.It consists of an inscription,dated 1897,with the names of William Dickey and th ree other individuals.Dickey was one of the first white men in the region.It is not yet known if this site is eligible to be listed on the National Register of Historic Places.Actual construction of the Portage Creek bridge would require mitigation measures to prevent erosion into salmon spawning areas.Long-term erosion associated with segment 'l-A is not anticipated. (vii)Segment Suitability This segment eliminates the less desirable portion of Segment l-A,with its difficult side hill construction and r35/a28 9-52H Supplement environmental impacts.The trade off is a major bridge at the mouth of Portage Creek that would impact the construction schedule by requiring two or more years to construct. (we)Segment 2-V (i)Description Segment 2-V is a variation of 2-U.It branches off just before 2-U crosses Portage Creek.Segment 2-V instead crosses the Susitna River,and proceeds to the Devil Canyon Damsite along the south side of the river where it joins line 2-1.This segment is fou rrniles long.See Figure 9.10B. (Il)Line and Grade Maximum allowable grades and minimum curvatures are used on this segment,but it stays within the design criteria. (iii)Drainage Features Several ravines are crossed on the s »uth side of Devil Canyon.Though they drain fairly small areas,the deepness of the gorges may indicate that short bridges would be cheaper than culverts under massive fills. r35/a29 9-52I .~ i; !..;-, Ii'I '/~ REVISED ra;;l FIGURE:9'.~DB1IJIIJ .-, -,- ,.,:,••~'i,,1;}:::"'t1 ...;__ "'",,~,,.'".''J.-"';:';".-\:c-+'r-;"" ",•,..-r '1,$'<'""1".

(v)Soils The problems associated with these soils -frozen basal ti II, with colluvium on the steep slopes -are as discussed else where (see Segments 2-RRR in this supplement and Segment 1-A in the main report). (vi)Environmental Impacts The only impacts noted for this segment are on the potential raptor nesting areas found within Devil Canyon.

(iii)Drainage Features No significant featu res are encountered. (iv)Bridges No bridges are needed. (v)Soils Soils are similar to those for Segment 2-U. (vi).Environmental Concerns By "short-cutting"around the north end of Segment 2-U, impact on cabins in that area is reduced. (vii)Segment Suitability This segment is a suitable connection between Segments 2-T and 2-U. r35/a3l 9-52M Supplement (za)Segment 3-D (i)Description The short segment starts at Line 3A near Big Lake,passes west of Deadman Mountain,and then joins Line 3C.While it shortens the overall length of road from the Denali Highway to Watana,it involves more difficult terrain.See Figure 9.11A.The line is eigtht and one half miles long. (ii)Line and Grade Maximum grade would be utilized over most of the length of this segment,in order to clear the pass between Deadman Mountain and the mountains to the west. (iii)Drainage Feature The line parallels a marshy tributary of Deadman Creek south of the pass.Several side branches would be crossed with culverts.North of the pass,the headwaters of Deadman Creek are paralleled,and crossed just before joining Line 3C.This crossing would also be via culverts.

Iv)Soils No data available yet. (vi)Environmental Concerns A detailed environmental study of the area west of Deadman Mountain has not yet been completed,but it appears that this segment is more favorable from an impact standpoint. The road would be farther away from Deadman Creek,its tributaries and associated wetlands,thereby mitigating to some extent secondary impacts on waterfowl and grayling. The route also avoids the cultural resource areas around Deadman Lake and Big Lake. r35/a34 9-57D Supplement (viii)Segment Suitability This route is within the minimum design standards,but has more difficult terrain,higher elevation,and longer length than other alternatives.The higher construction costs, construction time scheduling and maintenance costs are offset by the lower environmental impacts,making this segment a viable alternative to 3D. r35/a35 9-57E Supplement r35/a36 CORRIDOR SELECTION Corridor Summary Supplement ......III II .".",..~_.~L ,-__.1< r ~.. ,- PREFERED ROUTE I N EACH OTHER CORRIDOR ALTERNATES INVESTIGATED PREPARED REVISE FIGURE ~12 I Supplement 9.4 Corridor Summary -Supplement Plans 1 to 11 R are very simple to arrange,with only one set of sections selected for each of the three main corridors.Plans 12 to HA,however,do not fit into this same pattern.Several different sections in each corridor were considered of equal merit for further investigation and 'incorporation into plans.For clarity, the breakdown of segments,sections and corridors is resummarized on Table 9.4,according to the following system of ranking. 1.Corridor -denotes a wide band.The th ree corridors are #1 (north of Susitna River),#2 (South of Corridor #1)and #3 (Denali Highway to Watana).All study was conducted within the three proposed corridors. 2.Segment - a proposed length of road or rail that may or may not be suitable for fu rther consideration. Some segments,such as 1-A stretch the entire length of a corridor,while others are much shorter pieces. Segments are not necessarily used in their entirety, they may be superceded at one or more places by other,more feasible,segments. 3.Section - a combination of one or more segments or pieces of segments found to be suitable for incorpora- tion into plans. 4.Plan - a combination of one or more sections to make a complete road and/or rail facility that can serve both dams. r35/a37 9-60 t3/<..j I Supplemt::/IL TABLE 9.4 CORRIDORS,SECTIONS AND SEGMENTS Corridor Section Description Segments Used 1 A-1 Parks Highway at Chulitna to Devil Canyon (N)*1-A A-2 Devil Canyon (N)to Watana (N)1-A,1-B,1-E,3-A A-3 Parks Highway at Hurricane to Indian River Area 1-A,1-G A-4 Parks Highway at Hurricane to Gold Creek Rail Spur 1-A, 1-G,2-T A-5 Indian River Area to Devil Canyon (N)2-U A-6 Indian River Area to Devil Canyon (5)2-U,2-V A-7 Indian River Area to Watana (N)1-A,1-B,1-H,1-E,3-A A-8 Parks Highway At Hurricane to Devil Canyon (S)1-A, 1-G,2-T,2-U, 2-V,2-W 2 B-1 Parks Highway at Chulitna to Gold Creek 1-A,1-F,2-L B-2 Gold Creek to Devil Canyon (5)2-1 \.0 B-3 Devil Canyon to Watana (S)2-A,2-B,2-F,2-G,2-JImB-4 Gold Creek Rail Spur to Devil Canyon 2-1I-'B-5 not used B-6 Devil Canyon to Watana (N)2-A,2-B,2-Q,2-5,1-C B-7 Devil Canyon to Watana (5)2-A,2-B,2-F,2-G,2-J,2-Q, 3 C-1 Denali Highway to Watana,east of Deadman Mt.3-A,3-C C-2 Upgrade Denali Highway n.a.
