A four-car crash on the M2 in Belfast caused traffic chaos on Friday.
The incident happened on the Northbound stretch, between York Street and Fortwilliam.
Police closed lanes 1 to 3 of the motorway. The PSNI said the situation was made worse due to passing motorists slowing down to look at the collision.
The crash scene has now been cleared following the collision, but delays remain at the Sydenham Bypass and York Street.
Emergency services attended the crash but it is believed there were no serious injuries.
