Drivers are reporting serious delays on the M1 northbound near Sheffield and the roads near to the junction.
The M1 Northbound at Junction 34 (Meadowhall) and the sliproad near the Tinsley Viaduct nearby is subject to long tailbacks right now.
Reporter George Torr, at the scene, said: "Traffic has moved about 100 yards in five minutes. It's bumper to bumper and there are pretty serious delays."
The traffic is thought to be caused by repairs to a motorway bridge, meaning that the M1 northbound is down to a single lane between Catcliffe and Meadowhall.
