Southbound I-280 in SF Will Be Closed Memorial Day Weekend

SAN FRANCISCO (KRON) — A stretch of southbound Interstate 280 in San Francisco for a safety enhancement project over Memorial Day weekend.

Southbound I-280 will be closed between downtown San Francisco and the Pennsylvania Avenue on-ramp starting at 9 p.m. on Thursday and will reopen 5 a.m on Tuesday, Caltrans announced.

Northbound I-280 will remain open.

This is the first of three scheduled extended closures planned during the upcoming holiday weekends. The next closure is scheduled for Fourth of July weekend followed by Labor Day Weekend.

“District 4 Management decided that inconveniencing the traveling public with three 104-hour long weekend closures (totaling 312 hours = 13 days) of directional freeway closures was a much more acceptable alternative, when compared to 7 miles back up every day, twice a day, for one year,” Caltrans said.

The project involves demolition of the concrete around the old bridge hinge, removal of hinge, installation of a new bridge hinge, and cure time for the concrete, according to Caltrans.
