MARTINEZ, Calif. (KGO) -- All lanes on southbound Interstate 680 in Martinez have reopened after a crash involving a big rig and several other vehicles caused a massive traffic backup Wednesday morning.

This happened just north of Arthur Road around 7:45 a.m.

The CHP says there were some minor injuries.

One driver rear-ended another, and that car hit the big rig, which crashed into the center divide.

The rig's fuel tank was punctured, spilling 80 gallons of diesel.
