A90 AT GLENCARSE OVERBRIDGE NOW FULLY OPEN TO TRAFFIC AFTER TEMPORARY REPAIRS COMPLETED

The A90 at Glencarse Overbridge between Perth and Dundee is now fully open to traffic in both directions after temporary repairs were carried out on the damaged structure during specialist testing and investigation works.

Traffic management on the A90, which was in place for the safety of the travelling public after the Overbridge suffered significant structural damage when struck by an overheight vehicle on 28th March 2023, has now been removed.

Although it has been possible to undertake temporary repairs while removing loose and damaged concrete, and subsequently fully reopen the A90, the primary deck element remains buckled and for safety reasons the single lane traffic lights will remain in place on the bridge flyover leading to St Madoes.

The public should be aware that there will be a requirement to install further traffic management arrangements on the A90 at Glencarse Overbridge in future to allow permanent repair work to be undertaken. Amey will provide an update on when the repair work is ready to commence as soon as possible.

The testing and investigation works over the past week have helped determine the full extent of the internal damage caused by the bridge strike, and inform what will be required by way of a permanent repair to restore the integrity of the bridge.

The incident in March resulted in significant damage to one of the steel primary deck elements and the concrete deck slab above. The steel load bearing element was also badly deformed.

A southbound lane closure was implemented for the safety of the travelling public after sections of concrete, measuring as large as approximately 24cm x 19cm, and heavy duty bolts were recovered from the bridge site, posing a severe risk to traffic using the A90.

Temporary repairs were delayed after ecology surveys, which are statutorily required to be undertaken prior to the commencement of any detailed structural investigations and repair works, identified protected species in the vicinity of the bridge.

Amey would like to thank the travelling pubic and local communities for their patience while the processes were undertaken to allow the latest specialist testing and investigation works to be carried out.
