Traffic was moving slower than usual on I-70 Tuesday morning near the West Virginia-Pennsylvania state line due to work being done underneath the roadways.
Jay Ofsaniak of PennDOT tells 7News that longwall mining is going on underneath the interstate, and that has caused some damage to the road itself.
Officials warn commuters to be prepared to sit in traffic if you have to drive in this area.
Route 40 is available as a detour.
