Retrofit project to close NB I-280 into SF over Labor Day holiday

SAN FRANCISCO (KGO) -- Drivers beware -- a major seismic safety project will lead to a big freeway closure in just a few days.

Caltrans will close the northbound lanes of Interstate 280 between the Highway 101 junction and King Street in San Francisco starting Thursday at 2 p.m. It will not reopen until 5 a.m. Tuesday.

The four-day closure will allow Caltrans to replace two bridge hinges near the Cesar Chavez Street overcrossings as part of a seismic retrofit project.

Southbound lanes of I-280 will stay open.

Two similar closures happened earlier this year.
