The gas leak shut down both sides of I-805 in Chula Vista for three hours.
The California Highway Patrol shut down both sides of Interstate 805 after a gas leak in Chula Vista Monday.
The CHP started reopening all lanes around 5:45 p.m. The freeway had been closed from State Route 54 to State Route 905.
The break happened around 2:45 p.m. at East Palomar Street and Nacion Avenue. Fire officials told NBC 7, a Caltrans worker broke an 8-inch natural gas line with a back hoe.
Crews shut off the gas around 5 p.m., and residents were allowed to return home. People living in a half-mile radius of the break site and students and staff at Palomar Elementary School had been evacuated as a precaution.
SANDAG made State Route 125 toll-free Monday night to help alleviate traffic. The traffic jam could impact Monday night's Mumford and Sons concert at the Sleep Train Amphitheater.
