A large pothole opened up Friday on Interstate 880 in Oakland, causing lane closures for repairs, according to the California Highway Patrol.
The pothole, over Jackson Street, opened up in the No. 3 lane on southbound I-880, the CHP said, but the Nos. 1 and 2 lanes also were closed for the repair work.
Traffic was slow going past the area, and the CHP was advising drivers to use Interstate 580 as an alternate route.
It was unknown what caused the pothole to open up.
Caltrans estimated the repairs would be done and the lanes would reopen at about 8:30 p.m.
No further details were immediately available.
