Alaska Highway MP 1309 Tok River Bridge Repair
Location: Tok, Alaska Client: Alaska Dept. of Transportation & Public Facilities Start Date: 2018 End Date: 2019 This project replaces an existing 250-foot-long steel truss on the Alaska Highway over the Tok River, about four miles east of Tok. The project requires a 280-foot-long x 32-foot-wide detour bridge that will be built this fall, 2018. The new permanent structure is a three span, 360-foot-long x 43-foot-wide bridge founded on 24-inch driven pipe pile at the abutments and 36-inch driven pipe pile at the piers. The bridge superstructure is a typical 54-inch deep Deck Bulb-T precast girder design. Work will start fall, 2018, shut down for the 2018-2019 winter, and start again in early spring to begin with construction of the new bridge. |
