An investigation has been launched after hundreds of motorists were delayed in traffic jams after a major route through Perth was closed “in error”.
The closure of a lane on the old Perth Bridge saw traffic queued back to Scone and to the toll house on Dundee Road in the opposite direction.
A spokesman for Perth and Kinross Council said: “Diversion and road closure signage and cones laid out on old Perth Bridge on Sunday afternoon were there in error.
“They had initially been booked in with the company which carries out this work for the council to allow some investigatory work on the bridge.
“However, initial checks had demonstrated that further work would not be necessary and the booking was cancelled.
“Unfortunately, this information does not appear to have been received by the company which went ahead and implemented the road closure.
“We sincerely apologise for the impact this unnecessary closure had on road users.”
