A broken down bus has caused traffic jams on Trafford Way this afternoon.
The vehicle was stuck half way across the dual carriageway outside Doncaster railway station, where the road leaves the transport interchange and enters the tunnel under the Frenchgate Centre.
A police community support officer has been directing traffic at the scene.
Only one lane was open and traffic was tailing back.
Officials at First buses said they expected the problem to cause severe delays throughout Doncaster.
