An accident involving a jackknifed semi truck on westbound I-69 has forced the closure of at least two lanes of the expressway.

Reports also suggest that there may be a chemical spill on the roadway as a result of the accident.

The accident happened early Wednesday morning, but the cause of the crash are still unknown.  It's also unclear if anyone was injured because of the wreck.

Drivers on West bound I-69 should try to exit on Center road to ensure that they avoid early morning traffic back ups.
