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

The California Highway Patrol's Dublin division said the tanker was carrying ethanol, which needs to be offloaded from the tanker before it can be flipped upright.

The Tracy Police Department said the crash, which happened around 1:30 p.m., 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 CHP 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.
