A major search and rescue operation has been launched at the Clackmannanshire Bridge amid reports of a person in the water.
A coastguard helicopter has been drafted in and and the bridge is closed in both directions as the emergency services continue the hunt.
Coastguard rescue teams from Kinghorn and South Queensferry and Queensferry Lifeboat are also involved in the search, along with the police and fire service.
Drivers have been urged to use an alternative route.
A police spokesman confirmed the bridge was closed and added: “Please be aware that the Clackmannanshire Bridge is currently closed due to an ongoing incident.
“Please use an alternative route and we thank you in advance for your patience.”
A spokesman for HM Coastguard added: “We are currently dealing with reports of a person in the water in the Clackmannanshire area.”
The bridge over the River Forth opened in November 2008.
