Northbound I-805 closes overnight at Palm Avenue Friday into Saturday
Caltrans is closing all northbound I-805 lanes at Palm Avenue from 9 p.m. Friday, Oct. 9, to 9 a.m. Saturday for interchange construction. Drivers will be detoured via I-5 and SR-54.
All northbound lanes of Interstate 805 at Palm Avenue will be closed from 9 p.m. Friday, Oct. 9, until 9 a.m. Saturday, Oct. 10, so crews can install falsework — temporary support scaffolding — for the new Palm Avenue interchange, Caltrans said.
Northbound drivers will be sent to northbound I-5 and then east on State Route 54 to rejoin I-805. The Palm Avenue on-ramp to northbound I-805 stays open, while traffic from the Via de San Ysidro on-ramp will be detoured by way of westbound SR-905, Caltrans and KSDY 50 reported.
The roughly $31 million Palm Avenue/I-805 interchange project is a joint effort of the City of San Diego and Caltrans. Work began in June and is expected to finish in fall 2028. Caltrans notes that closure schedules can change because of weather.
