SAN LEANDRO (KTVU) -- A heavy wrecking vehicle is righting the trailer of a big-rig that overturned on a connector ramp from Interstate Highway 880 to state Highway 238 in San Leandro this morning, spilling a hazardous material and causing an evacuation of a nearby building.
Alameda County Fire Department tweeted Wednesday evening that 500 gallons of Glacial Acetic Acid leaked from totes into storage container & soil. They also said nearby storm drains were not impacted.
The crash was initially reported shortly after 11:20 a.m. on the ramp from northbound Highway 880 to southbound Highway 238.
A Caltrans building nearby was evacuated, according to the California Highway Patrol.
Minor injuries were reported to the driver of the big-rig.
CHP initially said the acid got into a storm drain, which emergency crews blocked off with an inflatable plug.
"There is a potential for a second spill when we right the vehicle," CHP Officer Joseph Fowler said earlier this afternoon. "We're trying to get the storm drain blocked off and cleared before we do that."
Firefighters said that personnel were in the process of righting the trailer at around 3:45 p.m.
Once that's complete they'll be able to open the trailer up and assess the damage inside.
Officers said that the ramp is expected to remain closed until around 9 p.m. while crews clean up and clear the scene.
