The wooden trestles that have given the surf break at San Onofre State beach its name are being replaced with a reinforced concrete structure. Construction starts soon on the project to replace the wooden trestles bridge.
SANDAG Senior Engineer Ramon Ruelas said the new bridge will increase safety on the second busiest rail corridor in the United States.
The railway bridge is used by Amtrak, Metrolink and Burlington Northern. About 45 trains cross the bridge every day.
Ruelas said salt air, fires and vandalism have taken a toll on the wooden bridge. He said beachgoers will have a pathway under the bridge to access the beach during construction.
"We may have to move them from one area underneath the bridge to another area," said Ruelas. "But getting to and from the beach is never going to be a problem for people wanting to gain access to the beach."
Ruelas said crews will stop work to protect the California Gnatcatcher and other birds during nesting season in February. The work will resume the following September.
The $12-million project is funded with federal stimulus funds and will provide about 150 temporary jobs.
The project is expected to be completed by early 2012.
