A322 Downshire Way Widening Scheme

Published 23rd August 2022

The A322 Downshire Way is considered by Transport for South East to be one of the top seven most congested corridor routes in the South East. The route forms a single carriageway bottleneck within adjacent sections of the A322-A329 corridor. This scheme seeks to remedy this by reducing congestion and cutting journey times in this busy area.

Part of wider plans for development growth in the Bracknell Forest region, the improvements will help prepare the highways network for the proposed addition of 11,000 new homes as part of the emerging Local Plan for further growth up to 2034.

Our infrastructure and environment team provided the design of the scheme which consisted of ‘dualling’ almost 1 km of single carriageway in a congested outer urban bottleneck. Fully modelled in 3D using Autodesk Civil 3D, the scheme included new carriageway, adding signals to an existing priority junction, installation of street lighting and drainage, widening of a reinforced concrete pedestrian underpass and earthworks design for embankment widening.

Nick Rose, Transport Engineering Manager, Bracknell Forest Council: “We were particularly impressed with the 3d modelling aspect of Waterman’s design, which ensured the best possible alignment criteria were achieved whilst fitting the new corridor within the existing constraints. The 3d modelling provided certainty over the extent of earthworks required and saved considerable cost and time during construction as it retained the existing carriageway construction with minimal build-up of surfacing, reducing costs and helping to facilitate the switching of traffic during the construction phase. Overall, we are very pleased with the services provided by Waterman and we would be happy to recommend them.”
