Materials Pit, 2007MP 47 Dalton Highway
Dalton Hwy project MP 37-49
WAAPS Project PurposeConnect State’s existing highway system with Seward Peninsula highway systemg y y
Facilitate regional community and resource development
Planning Steps
Review historical studies and routes → over 200 documents and 80
transportation studies
Identify corridor evaluation criteria → community and resource
access, environmental and land use constraints, costs
Define/evaluate preliminary alternatives/ p y
Recommend corridor → Yukon River Corridor
D fi i i t iti i l j b Define economic impacts → communities, mineral resources, jobs
Define next steps
Evaluation Criteria
Communities → population, distance to corridor and regional
hubs
Mineral Resources → value, distance to corridor
Environment →wildlife, wetlands, streams, Iditarod Trail
f Land Ownership & Management → Native & federal lands,
protected lands
Engineering & Costs → construction, maintenance
Preliminary Corridor Alternatives
Road Design Criteria Low‐Volume Industrial Road Standards
50 h d i d i h d d d• 50 mph design speed with some reduced speed areas• Anticipated Average Annual Daily Traffic (AADT) less than 400• Road construction will vary, depending on existing soils
Typical Roadway Section• 30’ total roadway surface width (12 ft. lanes, 3 ft. shoulders)
• 24” ft. sub‐excavation• 64” embankment material• Geogrid fabric• Unpaved with 8” crushed aggregate surface

Access to rich Ambler mining district
Crosses Koyukuk & SelawikNational Wildlife Refuges
Least cost to construct and Crosses Nulato Hills ACEC
Advantages Challenges
Benefits greater population Topography (steep grades)
Makes use of ~70 miles of Less documented mineral Least cost to construct and maintain
Crosses Nulato Hills ACEC
Fewest topographicalchallenges
Phased construction not as advantageous
Elliott Highway value near route
Fewer negative impacts to land and environment
Higher estimated cost to construct and maintain
P t ti l t h N Y k Ri ig
Good terrain for future rail and/or gas line
Longer distance between Fairbanks and Nome
(724 miles)
Potential to enhance intermodal transportation
system (Yukon River barges)
New Yukon River crossing required
Greater opportunity forphased construction
Shorter distance between Fairbanks and NomeFairbanks and Nome
(708 miles)
Yukon River Corridor
Yukon River Corridor – Route 2b
Total Project Cost → $2.3 to $2.7 billion• Construction of road bridges maintenance stations• Construction of road, bridges, maintenance stations• Engineering, environmental mitigation, right‐of‐way acquisition• 20% contingency
Economic Benefits → Passenger travel, fuel delivery, freight & mail, mining support, energy & power infrastructure
Refining the Cost Estimate → additional engineering & geotechnical information in Refining the Cost Estimate → additional engineering & geotechnical information in later phases • Terrain, wetlands • Economies of Scale
• Soil conditions • Project phasingB id C t ti li t
Annual Routine Maintenance → $14.9 million• Compared to the Annual Dalton Operations Maintenance Budget of $13.6 million for FY 10 and $15.5

Economic Impacts of theYukon River CorridorYukon River Corridor
Six case study communitiesT K k k• Tanana • Koyukuk
• Ruby • Koyuk• Galena • Nome
Case study minesKoyuk, 2008
• Ambler • Illinois Creek• Donlin Creek • Sample placer mine

Economic Benefits
Communities
$19 1 illi l i i f l f i ht• $19.1 million annual savings in fuel, freight,
mail transport
• Approximately $3,900 annual savings per pp y $ , g p
person
• More affordable and flexible options for
year‐round passenger travel
MinesRuby 2009
• $120 million annual savings in transport of
fuel, freight, mine concentrates

Economic Impacts of the RoadOther InfrastructureOther Infrastructure
Energy/Power
• Trucked propane instead of barged diesel could save communities
$13.5 million per year (about $2,700 per person)
• 30% to 50% reduction in costs to build pipeline or electrical
transmission infrastructure along road corridortransmission infrastructure along road corridor
Rail
• Support of long‐term rail development
Other Socioeconomic Effects Jobs → creation of approximately 1,590 new jobs at case study mines, average monthly wage of $7,000
Improved access to public services → education, health care, emergency/safety services
Reduced costs of community capital improvements
Increased access to subsistence
areas
Dalton Hwy MP 144-175 project
Next Steps Public Involvement → Communities, Native Organizations and Tribal
Governments, Mine Owners
Advance Route Mapping → GIS, LIDAR, Aerial Photography
Field Studies → Engineering & Environmental field investigations
Engineering Analysis → Further definition of corridor using field studies and mapping, refined costs
Implementation Planning → Construction phasing, right‐of‐way acquisition, funding
Current Next Steps
What $1 million in Capital funds can accomplish:
• Overall Objectives for Next Study Phase:– Obtain broad public input on the alternatives considered in the WAAPS Corridor Planning Report
– Conduct additional limited analysis of selective new options proposed or refinements of existing options proposed during the public review
– Identify a proposed staging plan and alternative construction techniques
Current Next Steps
• Public Involvement Task:– Public Meetings in various communities along the three Corridors– Stakeholder Meetings, Meetings with Native Organizations, Tribal Governments, and Mine Interests
• Staging Task:– Identify options for staging project into useable logical construction segments.
– Identify alternative construction techniques, standards, and interim modal alternatives to lower initial costs
