A number of lanes on the M2 northbound out of Belfast are blocked following a crash on Thursday morning.
A one-vehicle road traffic collision has closed lanes 4 and 5 where the M2 and M3 merge leaving Belfast.
This has caused long delays back on the M3 and A12 Westlink and drivers are advised to avoid the area.
A spokesperson for the Police Service of Northern Ireland said: "Motorists are advised of long delays at the junctions between York Street and Duncrue, M2 Northbound, due to a one-vehicle road traffic collision.
"Please seek an alternative route for your journey."
