San Francisco Westbound 80 to Northbound Hwy 101 Weekend Closure
Ramp Connecting Westbound I-80 to Northbound Hwy 101 in San Francisco to Close for Weekend
Caltrans will close a busy connector ramp in San Francisco that links westbound Interstate 80 to northbound Highway 101. The closure will last a full weekend, starting 10:00 PM, Friday, September 24 until 5:00 AM, Monday, September 27. During the closure, Caltrans will replace a guardrail that was badly damaged after being struck by a semi-truck last October.
Motorists arriving in San Francisco via the Bay Bridge typically use the connector ramp to access destinations in central, northern, and western San Francisco.
The ramp is often busy, serving nearly 2,000 vehicles per hour during peak periods, including many hours during the weekend.
Motorists should plan for delays on westbound I-80, including the Bay Bridge, as vehicles normally taking the connector ramp will choose upstream ramps including the Fremont, Fifth and Ninth street ramps, which are usually crowded on weekends.
The 7th Street on-ramp (which is signed for Hwy 101 despite connecting to westbound I-80), will be closed for the weekend to reduce traffic on I-80 and prevent back-ups on city streets.
Except for the westbound I-80 to northbound Hwy 101 connector ramp and the 7th Street on-ramp, all on- and -off ramps to I-80 and Hwy 101 in San Francisco will remain open during the weekend.
