VACAVILLE — A big rig is on its side blocking the Davis Street on-and-off ramps.
Crews are working to prevent vegetable oil that is leaking from the trailer from flowing into nearby storm drains, police said. The big rig was carrying more than 6,000 gallons of oil.
Both the on-and-off ramps are closed. They are not expected to reopen until 1 a.m.
The CHP is investigating.
