Drivers have said they have been stuck in queues for hours on the M60 motorway as emergency services responded to an incident.
Traffic had come to a standstill on the clockwise carriageway earlier between Sale and Stretford as Greater Manchester Police (GMP) responded to the incident at a nearby bridge.
National Highways said emergency services remained at the scene, and people have been urged to find alternative routes as the “severe delays” could last until after midnight.
A GMP spokesman said the “cooperation and patience of the public is appreciated whilst we work to bring this incident to a safe conclusion”.
The M60 was shut in both directions between junctions six and eight at about 17:50 BST.
All lanes are now open in anti-clockwise direction, but those running in the opposite direction are not expected to clear until about 00:15, National Highways said.
