The North Torrey Pines Road Bridge will soon be going under construction to repair and retro fit the 77-year-old structure.
Del Mar city officials say the bridge is in need of repair because of a combination of reasons including age and the salt air from the nearby ocean that has begun to corrode the concrete columns.
The bridge, located next to the North Torrey Pines State Beach, is a historical landmark was built between 1932 and 1933 and handles more than 20,000 cars each day.
The bridge will remain operational during the retrofit. The city says it does not expect any daytime road closures.
The project is expected to last two years. The reconstruction of the bridge is expected to cost $13 million and will be paid for by federal and state resources, officials said.
