SAN FRANCISCO (CBS SF) — Caltrans’ work is right on schedule for the Interstate 280 earthquake retrofit work, and the San Francisco portion affected should reopen on time Tuesday morning at 5:00 a.m. after being closed since Thursday afternoon so work could take place during the lighter Labor Day Weekend traffic.

The closure between U.S. Highway 101/280 interchange and King Street in downtown San Francisco began Thursday, August 28 at 2 p.m. The northbound direction was shot down.

This is the third and final in a series of closures planned during holiday weekends this year, as Caltrans works to replace broken hinges along the viaduct between Cesar Chavez and 24th streets.

Caltrans engineer and project manager Joon Kang said the broken hinges were discovered during a biannual inspection.

“There are many hinges throughout the entire structure, but only four of them were damaged,” he said.

Kang said the hinges, which allow for expansion, contraction and movement during an earthquake, likely took on more stress than those in other areas.

Caltrans expects that there will be significant travel delay during this northbound closure and advisers travelers to take alternate routes and public transportation when possible.

The on-ramps affected by the closure include Alemany Boulevard, the Highway 101 connector to northbound Interstate 280, 18th Street and Indiana Street.

Northbound on-ramp closures include:

  • Alemany Boulevard on-ramp
  • U.S. 101 connector to northbound Interstate 280
  • Indiana Street/25th Street on-ramp
  • 18th Street on-ramp

Southbound I-280 will remain open during this closure.
