A van has crashed into the barriers at the railway line in Broughty Ferry.
The barriers have been badly damaged amid reports the van driver took off from the scene.
Eyewitnesses say the van drove at the barriers which were closed at the time for an approaching train.
The railway line is still open but the road remains closed.
Police are understood to be trying to trace the driver.
Motorists are being asked to avoid the area at the moment in a bid to prevent congestion.
‘Lots of tooting from the train’
It is understood no one was hurt in the incident which took place in Gray Street at around 3.45pm on Saturday.
Eyewitnesses spoke of “lots and lots of tooting” from a train approaching the level crossing.
A Police Scotland spokesperson said: “Officers were called to Gray Street in Broughty Ferry around 3.45pm on Saturday, April 23, following reports of a vehicle crashing into the barrier of a level crossing.
“There does not appear to be any injuries, and officers remain at the scene carrying out enquiries.
“Locals are being asked to use an alternative route if possible to avoid congestion.”
One onlooker said: “I was told that a van hit the barrier and drove off.
“Apparently the barrier was coming down and a white van tried to go through it.
“The train was tooting its horn a lot.”
A spokesman for Network Rail said engineers had fixed the barriers but were still working to resolve other issues at the bridge.
They added: “The rail line is open but the road will remain closed to keep everyone safe until the warning lights are fixed.”
