Aecom has won the design services deal for the new third Menai crossing bridge in north Wales.
The consultant will undertake the key stage 2 appraisal of options and develop designs for the bridge, which will provide a third link between Anglesey and north Wales.
Aecom will deliver bridge and highway engineering services, transport planning, traffic modelling and environmental services as part of the deal with the Welsh Government.
Knight Architects and environmental consultancy Richards, Moorehead & Laing will work as subconsultants on the project.
The bridge will be the third link over the Menai Strait, following the Victorian-era Menai Bridge and the Britannia Bridge (pictured), which was rebuilt in the 1970s.
It will aim to increase capacity, reliability and journey times along the route from the M53 with Holyhead Port in Anglesey.
Aecom will also review the potential impact of the proposed scheme on the two existing bridges and aim to develop a design that “minimises impact on the environment and is sympathetic to the existing crossings”, according to the firm.
The consultant has already worked to deliver a strategic business case for the scheme and will start work on the design options immediately.
Aecom highways director for Europe Dave Beddell said: “A much-needed third crossing on the Menai Strait will keep traffic moving along the strategic A55, helping to boost economic growth in north Wales and Anglesey.
“Aecom brings a breadth of experience in the delivery of major bridge and highway infrastructure to take this exciting project to its next stage of development.”
