Traffic chaos will return to Highway 101 near San Francisco International Airport (SFO) and the South Bay due to construction to replace the 1930s Cordilleras Creek Bridge.

Southbound traffic on the highway was snarled over the final weekend in September, causing traffic issues around SFO due to work on the replacement bridge. 

Northbound Highway 101 lanes will be closed this weekend from 10 p.m. Friday through 5 a.m. Monday for further construction. The work is expected to affect weekend travel to SFO. 

The current 1930s triple-box culvert bridge has reached the end of its life span, officials said. It will be replaced with a modern single-span bridge to allow increased water and fish flows.

Caltrans crews will begin work Friday to replace this triple-box culvert first installed in 1930 over the Cordilleras Creek in Redwood City with a single-span bridge over Highway 101.

The work will require traffic to be rerouted between the highway's exits at Whipple Avenue and Holly Street along Industrial Way in Redwood City.

Drivers could take the northbound Interstate 280 as an alternative to Highway 101. More information is available at SM101cordillerascreekbridge.com or 510-286-0319.
