I-20 westbound in Bossier City is closed because of an overnight wreck involving an 18 wheeler.

Traffic is being diverted onto I-220 because of the cleanup effort.

The accident happened just west of the Airline Drive exit. Police say the driver left the roadway, hit a guardrail, and then struck the opposite concrete guardrail on the overpass. The truck caught on fire. The big rig driver was not hurt.

No idea yet how long it will take to clean up the mess.
