Caltrans has announced that a 1.6-mile stretch of eastbound Interstate 80 in San Francisco will be closed from 11 p.m. Friday to 6 a.m. Monday as crews work on a two-year rehabilitation project for the aging freeway. Significant traffic congestion and delays are expected in the SoMa, Mission Bay, and surrounding areas, and drivers are strongly encouraged to use public transportation if possible.

Why it matters

The closure of this major freeway artery will have a significant impact on traffic flow in and around San Francisco, potentially causing gridlock on surrounding streets and highways. The rehabilitation project is necessary to address the deterioration of the 71-year-old freeway infrastructure, which supports thousands of vehicles daily.

The details

The eastbound closure will span from 17th Street to 4th Street. Motorists will not be able to traverse this 1.6-mile stretch and will need to exit at Vermont Street or 9th Street, then travel on Bryant Street to reenter the freeway at 5th Street. The connector ramps from northbound and southbound Highway 101 to I-80 will also be closed, though the Bay Bridge will remain open.

  • The closure will begin at 11 p.m. on Friday, April 18, 2026 and last until 6 a.m. on Monday, April 21, 2026.
  • The two-year freeway rehabilitation project is currently underway.
