A crash has closed a stretch of Interstate 79 in both directions in Butler County. 

According to PennDOT, both the northbound and southbound lanes have been closed between Exit 78 (Cranberry/Mars) and Exit 88 (Zeilienople) due to a multi-vehicle crash. 

The closure will remain in place until the crash is cleared. 

Meanwhile, PennDOT has reminded drivers that a speed limit restriction is in place on I-79 due to winter weather. Speed has been reduced to 45 in both north and southbound directions between PA 5 in Erie and all the way to Butler. 

We have a crew heading to the scene and will bring you the latest updates on KDKA-TV and KDKA.com.
