A90 Glencarse Overbridge flyover to reopen under traffic lights on Wednesday 29th March

Glencarse Overbridge flyer to reopen to one-way traffic


The A90 Glencarse Overbridge flyover between Perth and Dundee is scheduled to reopen under single lane traffic lights on the evening of Wednesday 29th March after it was closed following a bridge strike.

The bridge suffered significant damage when it was struck by a vehicle during the incident around 12.45pm on Tuesday 28th March, resulting in its closure for the safety of road users and pedestrians.

The bridge currently remains closed to traffic and one lane on the A90 southbound below the bridge is also closed for safety reasons due to the extent of damage to the structure.

Open to single lane traffic

Amey engineers completed detailed inspections of the damaged overbridge at Glencarse for over eight hours following the accident, and work is ongoing to open the bridge to single lane traffic under temporary traffic lights this evening.

Both the single lane system on the flyover and closure of the A90 southbound lane will remain in place for the foreseeable future.

Plans for a long-term solution are being progressed and any permanent repairs will involve a complex design process, with teams working to address the substantial damage to a number of key components both beneath and within the structure.

Damage to critical parts of the bridge

The incident resulted in significant damage to one of the steel primary deck elements and the concrete deck slab above. The steel load bearing element has also been badly deformed and will need to be repaired.

The bridge was previously damaged in October 2019 in a similar accident when it was struck by a vehicle, with the structure fully reopened to traffic more than 12 months later in November 2020.

Similar timescales for permanent repair work to be completed following this latest incident are anticipated.

A complex repair process

Operating Company Representative for the North East NMC, Tom Wallace, said: “Our engineers have carried out a detailed inspection of the structure and have identified extensive damage to critical parts of the overbridge.

“Road users and local communities should be assured that we will do everything we can to repair the bridge as quickly and safely as possible to allow it to be fully reopened.

“However, this is a complex operation and, as previous essential repair work on the bridge has shown, can often take a considerable amount of time to complete.

“Amey would like to thank all road users and the local community for their patience in advance.

“Motorists are encouraged to plan their journeys in advance by checking the Traffic Scotland website for up to date travel information.”
