The big rig overturned and spilled about 5 gallons of diesel.

The carts of wine have to be unloaded one-by-one before the big rig can be uprighted and towed away.

Drivers are advised to avoid the area. KRON 4’s Robin Winston says to use city streets instead.

CHP estimates that the scene will be cleared around 9 a.m. or 10 a.m.

When the crash first happened, all lanes of southbound I-880 were closed causing a gridlock on the freeway.

The cause of the collision is under investigation. Police are asking any witnesses to give them a call.
