Contractors are hoping for good weather this weekend to start work on a bridge demolition as part of the Aberdeen bypass scheme.
Traffic is due to switch today (Wednesday) from the A90 northbound carriageway at Stonehaven to the newly-built southbound carriageway in advance of contractors starting to bring down the bridge that carries the road over the B979 Netherley Road. However, the operation can be undertaken only on completion of preparatory works that are dependent on weather conditions.
Breaker-equipped excavators will tear down the structure to allow the bypass contractor to begin construction of the new northbound carriageway bridge section.
A Transport Scotland spokesperson said: “By moving traffic over to the southbound carriageway at Stonehaven, the contractor is aiming to undertake the demolition of the existing A90 northbound carriageway bridge this weekend. However, the demolition works will only progress if weather conditions are favourable over the next few days.”
• Elsewhere, Network Rail will soon begin a year-long £4m programme to replace and widen a bridge over the railway at Baillieston, Glasgow.
The renewal of the bridge is part of a rolling programme of maintenance work on rail structures to extend their lifespan. Work will start September 4 and includes demolition and reconstruction of the deteriorating concrete bridge deck.
Replacing the deck will ensure the bridge remains fit for purpose and the wider structure will also allow the removal of traffic lights and weight restrictions.
Utilities that serve the neighbourhood will be diverted on to a temporary structure, a lengthy process that will be required again after the deck has been reconstructed. Work on the bridge will include periods of piling, installation of foundations and steelwork, as well as demolition and other activities.
