Rep. Mike Thompson announced Monday that $2 million in federal transportation funds will be directed to Caltrans and local agencies to use in rebuilding quake-damaged roads, bridges and other transportation infrastructure in the Napa Valley.

Thompson, D-St. Helena, said the money, provided by the U.S. Department of Transportation’s Federal Highway Administration, would help offset repair costs, now estimated by Caltrans to top $10 million.

Caltrans has identified bridges and roadways that were damaged in the magnitude 6.0 quake, including surface cracking on Highway 121 north of the Sonoma-Napa County line at Cuttings Wharf as well as “significant stress to joints on bridges including the Napa River Bridge.”

All bridges are safe and open to traffic, according to a statement issued by the Federal Highway Administration. The state is now trying to determine whether bridge joints should be repaired or replaced.
