The Alaska Department of Transportation and Public Facilities (ADOT&PF), in cooperation with the Federal Highway Administration (FHWA) will rehabilitate 10.5 miles of the Seward Highway between the Trail River Bridge (MP 25.5) and the Sterling Wye (MP 36).
The Seward Highway is the only road that connects the communities of Moose Pass and Seward to the rest of the State, and is often used by other residents of Southcentral Alaska.
In most locations, the posted speed limit is 55 miles per hour (mph). Through the community of Moose Pass, the highway has a posted speed limit of 35 mph. The roadway is constrained by several lakes (Tern Lake, Upper Trail Lake, and Lower Trail Lake), mountainous terrain, and the Alaska Railroad which parallels the roadway from approximately Lower Trail Lake to Upper Trail Lake.
Few improvements have been made to the portion of the Seward Highway from MP 25.5 to 36 since its initial construction in 1950, except for repairs after the 1964 earthquake and flooding events. The current highway includes two 12-foot travel lanes and shoulders of varying widths (from 2 to 6 feet).
The Seward Highway MP 25.5 to 36 Rehabilitation project is considered a “3R” project; it will resurface, restore, and rehabilitate the corridor, and by doing so improve the driving surface, and extend the service life of the roadway. The roadway will be rehabilitated along the existing alignment, the existing pathway will be resurfaced, guardrail will be upgraded, site distance will be improved by clearing vegetation, and drainage conditions will be improved. The project may also include shoulder widening where possible, and additional pedestrian amenities and traffic calming through Moose Pass.
