Two people were killed in an early morning crash Wednesday on Interstate 81 Northbound, tying up traffic for several hours. The crash happened around 2:30 a.m near the exit to the Wilkes-Barre Scranton International Airport and the Avoca exit. State police say it involved a tractor-trailer and a vehicle. No word on the identification of the two killed. Both lanes on the interstate had been closed and detours were in place, causing traffic congestion on 81 North and Southbound as well as surrounding roads including Route 315 and Birney Avenue in Moosic. The road has since reopened.
