That's because Caltrans is replacing joint seals on the upper and lower decks of the bridge. Work will begin on the upper deck at nine Monday night, until 4:00 a.m. the Tuesday.

The overnight repair work will fluctuate between the upper and lower decks, depending on the day.

Caltrans says up to four of the five lanes could be closed for the work, which could lead to extensive delays.
