Aberdeen City Council is seeking bids for a contract to build a new 90m span bridge across the the River Don.
The scheme, known as the Third Don Crossing, requires 2.5km of new road and an additional smaller bridge to the north of the main structure to span the Mill Lade watercourse.
The project, to the north of Aberdeen city centre, will entail the realignment of some side roads and private access junctions to accommodate the new approach road.
An Aberdeen City Council engineer told NCE that the scheme was “technically a roads contract with a couple of bridges”, and as such there would be no architect.
The engineer added that the main bridge would be a steel box girder structure, while the smaller Mill Lade bridge would probably be prestressed concrete.
The new crossing is needed to relieve congestion on the Don’s two existing bridges – the A956 Bridge of Don to the east of the proposed site, and the A90 Persley Bridge to the west.
The council also hopes the scheme will encourage development north of the city’s A90 Parkway, a main artery that cuts west to east above the Don.
