Drivers on the Tay Road Bridge faced a series of “short closures” on Sunday morning.
Emergency repairs were carried out on the Fife-bound side of the bridge, where there is currently a contraflow.
The Dundee-bound side is already closed for long-running roadworks.
A Tay Road Bridge post on X said: “This morning there maybe several short closures to allow an emergency repair to the live carriageway.
“Delays will be kept to a minimum. Sorry for the inconvenience.”
A later post confirmed the works had been completed.
Resurfacing works on the bridge’s Dundee-bound carriageway started in June.
A contraflow has been in operation since, with one lane open for traffic heading in each direction.
The roadworks were originally expected to run until November but the date was pushed back to December 15.
The second phase of the project is to begin in March.
