Camino del Mar over San Dieguito Bridge Replacement
The City of Del Mar has launched a multi-year project to replace the Camino Del Mar bridge over the San Dieguito River.
As planned, the new bridge would accommodate one traffic lane in each direction and bike lanes and sidewalks on both sides. With fewer pilings than the existing structure, the replacement bridge would improve the hydrology of the river and the ecology of the environmentally-fragile wetlands.
The engineering design and environmental permitting is currently underway. A 36-month construction is expected to begin in late 2026. Beach access will be maintained during construction.
Located north of Sandy Lane and south of Via de la Valle, the existing bridge was built in 1932, widened in 1953, and modified in 2001. In 2010, a study identified corrosion and vulnerability to earthquakes and recommended replacement as the most cost-effective solution.
The estimated construction cost is approximately $50 million. This project is eligible for almost 90 percent reimbursement from federal funding under the Federal Highway Administration Highway Bridge Program.
