These bridges have deteriorated from the salt air on the coast and are in need of repair. If nothing is done, the bridges would eventually have to be replaced. They might also need to be load rated, meaning that large vehicles over a certain weight would not be able to travel over them.
The bridges will receive titanium and steel reinforcements on the bridge deck and along the girders under the bridge to strengthen them. This will require cutting narrow slots and drilling small holes to insert the reinforcements, which will then be secured to the bridge with an epoxy.
Bridge rails will be replaced with new rails that meet current standards. A variety of methods will be needed to remove the old rail while not damaging portions of the bridge that remain, including chipping and hydro-demolition.
The bridges will also receive cathodic protection, which provides a shield of protective coating to prevent the steel from corroding.
This is one of a series of bridge cathodic protection projects along the Oregon Coast, designed to keep the structures in service for years to come.
