In case you noticed a difference in air traffic today, the center runway at Sea-Tac International Airport has been closed this afternoon.
Airport spokesman Perry Cooper said crews discovered a hole in the south end of the runway and are working to patch it. Air traffic is using the third runway, causing a shift in the routes planes are using in the air.
No delays have been reported. The center runway should be up and running by about 4:50 p.m.
