Regent Street flyover, which carries the A64(M) motorway over the A61 dual carriageway in Leeds, was constructed in the 1960’s and had reached the end of its useable life. This design and build project (WSP and Balfour Beatty) involved complex demolition and reconstruction within a politically sensitive city centre environment. The new flyover was completed in November 2022 and is now a striking piece of infrastructure within the city centre of Leeds, facilitating over 70,000 vehicle journeys per day.

Several aesthetic features have been incorporated into the design to form a centre piece for the major regeneration taking place in a historically deprived area of the city. The high-quality design was created by laser scanning and 3D modelling the existing and proposed structures which provided confidence in design and construction.

Unique challenges were attached to this project, requiring collaboration, innovation, and expertise. ECI with WSP and Leeds City Council (LCC) throughout the design process, enhanced through co-locating, supported successful mitigations to the following:

  • Demolishing the existing structure, which comprised large high-risk post tensioned concrete beams, in a city centre environment within 50mm of the adjacent flyover structure and other surrounding structures.
  • Undertaking such major civil engineering works within a city centre environment close to BBC Leeds, Leeds Playhouse Theatre, NHS England and the Hilton Hotel created considerable logistical challenges, mitigated through robust stakeholder management.
  • Negotiating the increased risk of working above a 6m wide culvert running beneath the A61.
  • Transporting 43m long structural steelwork into the city under special movement orders
  • Design and constructing a slender bridge.
  • Complex traffic management which required adherence to motorway regulations. Additional attention was required for cycle lanes and multiple pedestrian walkways.
  • Keeping the motorway operational and safe by utilising a £0.5m temporary propping system to support traffic loading over the existing tunnel and the new flyover during construction. The scheme won the 2023 ICE Y&H Centenary award and was highly commended.
