Lewiston-Clarkston Bridge, Idaho and Washington

Location. On the Snake River, River Mile 141.3, 1.7 miles upstream of the existing interstate bridge connecting the towns of Lewiston, Idaho, and Clarkston, Washington.

Existing project. The project consists of a new fixed high-level four-lane highway bridge and approaches on US. Highway 12 across the Snake River constructed at a cost "not to exceed $21,000,000." In December 1981, Congress authorized an additional expenditure of $2,200,000 for construction of Lewiston's North Ramp. An approach roadway from the bridge to 16th Avenue in Clarkston, Washington, was authorized in July 1983 at an additional expenditure of $800,000.

Final Environmental Impact Statement Supplement was filed with the Council on Environmental Quality on July 16, 1979.

Local cooperation. Non-Federal interests have provided without cost to the United States all lands, easements, and rights-of-way necessary for the construction of the bridge and its approaches, and after construction have agreed to own, operate toll free, and maintain the bridge and approach facilities. The non-Federal cost for the land and relocation are $755,193.

Operations during fiscal year. New work: Construction of the main bridge structure and Lewiston ramp is complete. Work started on the 1600-foot roadway from the bridge to 16th Avenue in Clarkston, Washington.
