UPDATE (12:01 p.m. on Tuesday, Oct. 31): All lanes of I-64 are back open following a crash that slowed traffic for hours on Tuesday.

UPDATE (5:45 p.m. on Monday, Oct. 30): One lane of I-64 westbound appears to be back open after a tractor-trailer rollover shut down all westbound lanes earlier Monday.

Vehicles can be seen moving slowly on a WV 511 camera near mile marker 55 after traffic was at a standstill for more than an hour.

KANAWHA COUNTY, WV (WOWK)—I-64 westbound is closed on the Dunbar-South Charleston bridge due to a crash involving a tractor-trailer.

Kanawha County Metro 911 says the westbound lanes will be closed for several hours at the 53.5 mile marker. Dispatchers also say that the tractor-trailer rolled over and leaked fuel onto the roadway. Officials with the South Charleston Fire Department say that 75 to 100 gallons of diesel leaked.

The truck appears to have been carrying plywood.

Metro 911 says traffic will be diverted off the interstate prior to the MacCorkle Ave. exit.

Drivers are urged to take an alternative route if possible.
