A portion of southbound Interstate 805 stretching from Sorrento Valley to University City will be closed beginning at 9 p.m. Saturday until 5 a.m. Sunday for construction, and again Sunday night to Monday morning.
All southbound lanes will be closed from the Interstate 5/805 split to Governor Drive, while a culvert replacement project gets underway beneath the freeway just south of Nobel Drive, according to Caltrans officials.
Drivers were advised they can use southbound I-5 to get to eastbound state Route 52 or eastbound Interstate 8 to reach southbound I-805 on the other side of the closure. Businesses and homes near Nobel Drive should expect construction noise and lighting throughout the weekend.
The closure will not impact MTS bus routes between La Jolla and University Town Center.
Caltrans said the $53.7 million culvert replacement project — dubbed the I-805 North Drainage Culvert and Asset Management Project — will rehabilitate drainage culverts and make pavement improvements across a nearly five-mile stretch of I-805 from state Route 52 to the I-5/805 split.
