Auxiliary Lane Project Makes Key Improvements along I-805 in South Bay

SAN DIEGO –– Today construction crews opened a new northbound auxiliary lane and a southbound general purpose lane along Interstate 805 (I-805) in National City, a move that is expected to improve overall freeway flow and safety, while alleviating congestion along I-805 in South San Diego County.

This joint effort between Caltrans and SANDAG, known as the East Plaza Boulevard Auxiliary Lane Project, extends lanes from State Route 54 to East Plaza Boulevard along I-805.

The new lanes are roughly a half-mile long. They extend the merging distance between on- and off-ramps to accommodate the maneuvering of vehicles entering and exiting the freeway. 

Today’s opening marks the completion of the first phase of the I-805 South Express Lanes Project, a $1.1 billion effort to create a modern transportation backbone for South County. Funding for the South Express Lanes Project is provided by TransNet, the regional half-cent sales tax for transportation administered by SANDAG.
