An overturned tanker truck collision resulting in injuries occurred on I-780 near 2nd Street in Benicia Wednesday morning. The truck has spilled asphalt across the westbound lanes, according to a Sig Alert.

The truck that overturned was hauling 6,000 gallons of hot asphalt. All lanes are currently blocked. The California Highway Patrol said no one was hurt in the crash, which happened just before 9:30 a.m.

The tanker ended up leaking across all the lanes of the westbound I-780 and on the right embankment of the freeway and into a ditch.

Environmental regulators have been called to assess whether any of the substance has reached local waterways. At least one resident asked authorities if the substance hit her fence.

All traffic is being diverted off the freeway at Fifth Street. The CHP is asking people to avoid the area while the cleanup is ongoing Wednesday afternoon. There is no estimate for when the highway will reopen.
