Alaska Highway: Tanana River Bridge Project
Hwy crossing Tanana River in Tok, AK

Last July, Alaska Department of Transportation and Public Facilities eliminated a bottleneck that limited the size of loads coming in and out of Alaska.

The $33.4 million Tanana River Bridge project replaced an almost 70-year-old bridge with the lowest load capacity and lowest vertical clearance of any bridge on the Alaska Highway in order to improve commerce and future development.

The old bridge was built in 1943 and needed an upgrade in order to keep up with the load size of the trucks needing to pass over the bridge. ADOT&PF built the new 903-foot bridge about 200 feet downstream from the original and included new features, while also incorporating the steel of the old bridge into the kiosk design.
