An accident on Interstate 77 backed up traffic for much of the afternoon.
Two tractor-trailers collided in the northbound lanes near the Emerson Ave exit.
It all happened in the northbound lanes, in the area where the route two construction work is going on.
Terry Hefner, chief of the Waverly Volunteer Fire Department, tells us one of the two trucks tried to merge onto the interstate, collided with the other semi.
The passing lane was shut down due to the construction work.
Neither of the drivers was hurt, but the wreck blocked the two northbound lanes of 77, backing up traffic as far as the route 50 exit.
the southbound lanes of 77 were not affected.
