It happened between Junction one at Fortwilliam and Junction two at Greencastle.
Three lanes were initially closed and traffic is tailed back to Yorkgate.
A PSNI spokesman said: "Two lanes of the M2 Northbound have been closed at Greencastle after a trailer shed its load.
"There are long delays on the Westlink and M3 approaches to the M2. Motorists are advised of ongoing delays and are advised to seek alternative routes if possible."

It happened at the Belmont Road roundabout.
A PSNI spokesman said: "The Belmont Road is closed between Hawthornden Way and Knock Road junction due to a two vehicle road traffic collision. Please seek alternative routes."
