Galvanic cathodic protection used to extend the life of a highway bridge in Oregon here.
At one time the state had planned to replace the bridge with a wider bridge, but the cost of a new bridge expanded to nearly $10 million from an initial estimate of $1.8 million because of environmental concerns with the creek it crosses. The cost of the reconstruction of the existing bridge is estimated at about $1 million.
