Overturned tanker shuts down I-205 west of Tracy near Alameda County line

By Richard Ramos

Both sides of Interstate 205 through Tracy were shut down Tuesday afternoon after an oil tanker overturned on the freeway, triggering a large hazardous materials response and major traffic delays, officials said.

The Tracy Police Department said the crash forced the full closure of the westbound lanes, just west of Tracy near the San Joaquin-Alameda county line. Traffic was being diverted on Mountain House Parkway.

Additionally, the California Highway Patrol’s Dublin division said that, further west, eastbound I-205 at the eastbound I-580 split has also been shut, with all traffic being diverted onto eastbound I-580.

Fire officials said crews were actively working a “large-scale hazardous materials incident,” and officials warned drivers to expect heavy traffic and extended closures in the area. No timeline has been given for when the freeway might reopen.

It was unclear whether any injuries had occurred.

This is a developing story and will be updated as new details come in.
