Drivers in East St. Louis are being asked to avoid Interstate 64 near mile marker four after a spill on the highway Tuesday afternoon.

Hazmat crews responded to an overturned semi on Westbound I-64 near mile marker four where a box truck leaked some kind of fluid.

On their Facebook page, the St. Clair County EMA warned drivers to avoid the area while they worked to clean it up.

The crash is caused backups in both directions.
