Summary

The Alaska Highway near Tok, Alaska crosses the Tanana River via a 288 m truss bridge constructed in 1944. Due to age, damage from a 2002 earthquake, and extensive pier scour, the bridge is being replaced in 2009-2010. Since it was originally constructed, the angle of approaching flow to the bridge has changed and currently approaches the right-bank pier at 45 degrees creating a large scour hole around the pier. The new bridge is being constructed 75 meters downstream of the existing bridge and a temporary construction causeway was built in 2009 upstream of the new bridge alignment. The effect of the causeway on the channel hydraulics at the existing bridge are of concern to ADOT&PF. Several potential causeway geometries and their [...]
