SAN DIEGO–All the southbound lanes of Interstate 5 from the I-805 merge to La Jolla Village Drive will be temporarily closed for bridge work from Thursday at 9:30 p.m. to March 9 at 5 a.m.

Crews will adjust the temporary support structures, known as falsework, on the Gilman Drive bridge project in anticipation of bridge concrete deck work.

Motorists should anticipate delays, follow detour signs, and take alternate routes to avoid potential congestion.

SANDAG, in partnership with UC San Diego and Caltrans, is building the bridge over I-5 at Gilman Drive, just north of the La Jolla Village Drive interchange.

The bridge and related roadway improvements will connect Gilman Drive to the west and Medical Center Drive to the east, a vital campus link for UC San Diego. The new bridge will add a second on-campus crossing over I-5.

Southbound motorists will be detoured via Interstate 805. Traffic controls and detour signs will be in place to alert motorists in advance.
