DUBLIN (CBS SF) — The three right lanes of southbound Interstate Highway 680 were shut down for more than 5 hours early Wednesday after a tanker truck crashed and spilled diesel fuel, according to the California Highway Patrol.

The lanes were reopened at 8 a.m. but the impact on the morning commute lingered.
