Anchor River Bridge Replacement

Project Description

 

The Alaska Department of Transportation and Public Facilities (DOT&PF), in partnership with the Federal Highway Administration (FHWA), is proposing a new bridge across the Anchor River on the Old Sterling Hwy at MP 8.4 in the town of Anchor River within the Kenai Peninsula Borough.

The existing through-truss bridge was installed in 1942 and has been retrofitted several times to extend its usable life-span. Load restrictions have been implemented on the bridge, inconveniencing local residents and creating inefficient detours for routine maintenance operations and other heavy vehicles. Old Sterling Hwy currently experiences seasonal flooding across the roadway south of the bridge.

This project will raise the roadway to prevent water from overtopping during the much higher design flood event. The new bridge will have 11’ lanes and 6’ shoulders in both directions, which will be an improvement over the existing one-lane bridge. The new bridge will not have height restrictions or load restrictions, unlike the current bridge which experiences both. Signage, striping, ditching, guardrail, riprap, and trail work is also being proposed.
