Drivers are facing major disruption on roads in Dundee and Fife after the Tay Road Bridge was closed on both sides.
The link has been closed since just after 12.45pm on Friday due to a police incident.
It is currently unknown what the cause is, however STV News understands officers were called to reports of concerns for a person.
HM Coastguard confirmed that the Broughty Ferry RNLI lifeboat had been dispatched to the scene, alongside Coastguard rescue teams from Arbroath and St Andrews.
The closure has caused queues throughout Dundee city centre, as well as towards Fife with tailbacks as far as the Forgan Roundabout.
A Police Scotland spokesperson said: “The Tay Bridge is currently closed.
“Motorists are asked to avoid the area or seek alternative routes.”
A spokesperson for HM Coastguard said: “HM Coastguard is currently dealing with an incident in the Tay Road Bridge area in Dundee.
“Just before 1pm on March 10, Coastguard Rescue Teams from Abroath and St Andrews and the lifeboat from Broughty Ferry RNLI were sent to the scene.
“Police Scotland and the Scottish Ambulance Service are also in attendance.”
