The California Department of Transportation has announced a long-term closure of westbound Interstate 210 Roxford Street on and off-ramps in Sylmar for paving work. Residents and local businesses located near the freeway may experience noise, vibrations and dust associated with construction activities.

Crews will be closing the Roxford Street on and off-ramps beginning Monday, Oct. 3 at 7 p.m. on westbound I-210 for up to 45 days.

The following ramps are scheduled to reopen:

Polk Street on and off-ramps beginning Friday, Sept. 16.

Yarnell Street on-ramp is open. The off-ramp is anticipated to reopen on Friday, Sept. 30.

The closure of the ramps will allow provide additional room for crews to pave the far-right lane. This is the last scheduled long-term ramp closure for the project.

Motorists are advised to use as an alternate route during the closure duration. All closures are weather permitting and subject to change. Drivers are encouraged to check traffic conditions before leaving to their destination by visiting the Caltrans Quickmap.

The work on I-210 is part of a $135.5 million project replacing all lanes of I-210 with new pavement from Wheatland Avenue to I-5. This project is funded by Senate Bill 1, the Road Repair and Accountability Act of 2017. Overhead sign structures, traffic loop detectors, center median barrier and the guardrail system are also being upgraded by this project.

Caltrans reminds drivers to be “Work Zone Alert” and to “Slow for the Cone Zone.”
