A322 Downshire Way dualling
Latest update - 16 June 2020
The A322 Downshire Way dual carriageway project is now complete. There is some minor snagging work and the final greenway elements which will be completed in October - the optimum time to plant the remaining trees and hedgerows. The new traffic signals will be monitored by the council and minor adjustments made to optimise their performance where needed.
We would like to thank everybody for their patience during the construction of this scheme.
We have been successful in securing government funds to undertake, in partnership with the Department for Transport, transport improvements to the A322 Downshire Way. This forms part of the important A329/A322 corridor linking the M3(J3) and M4(J10).
As part of the transport plan for this corridor, we have invested in upgrading junctions along this route over the last 5 years to provide a better managed corridor and more reliable journey times.
In March 2017, the Government launched the National Productivity Investment Fund which aims to unlock pinch points along strategic corridors affecting regional and local routes. We have been successful in securing funds to make the full length of Downshire Way a dual carriageway, which at present can be congested along its length. This congestion presents challenges for air quality and also acts as a constraint to growth within Bracknell and across the region.
You can find more on our National Productivity Investment Fund page.
Why is the scheme needed?
The scheme will improve traffic flow and journey times along Downshire Way which is currently congested during peak periods. It will also contribute to the council’s current plans for development growth, including the delivery of 11,000 new dwellings by 2026.
Main elements of the scheme
The scheme consists of the following main elements:
- widening the A322 Downshire Way to form a continuous dual carriageway (extending the 2 lanes sections to cover its entire length)
- lengthening the existing subway structure beneath Downshire Way
- signalisation of the Old Bracknell Lane West Junction with the A322 Downshire Way
- removal of the signalised bus gate across Downshire Way
- a central reservation (where required)
- diversion of the adjacent southern footway/cycleway to an alternative quieter route
- greenway works to improve the natural environment of the A322 Downshire Way and surrounding areas
The greenway project
The natural spaces alongside roads are important for making the borough visually appealing and they connect surrounding habitats for plants and wildlife.
To harness and increase the environmental benefits of highway corridors, this scheme incorporates a ‘greenway’ project. This project means that as well as replacing any trees that have to be removed, we will also be planting a wide range of woodland, hedgerow, meadows and wildlife habitat works to maximise the benefits for people and wildlife.
Wherever possible we will keep existing trees, but to create a larger highway some trees will have to be removed. The greenway project will minimise the impact of the highway changes and will also create a better natural environment for the future.
The key parts of the greenway project are:
- feature tree planting - in key locations to provide large trees for the future in prominent positions alongside the highway
- woodland enhancements - to improve the structure and quality of the woodland
- hedgerow creation - to improve the look of pedestrian and roadside edges and create valuable linear habitat to shelter and feed wildlife
- meadow enrichment - to improve the quantity, quality and appearance of roadside meadows
- interpretation and sculpture - to aid public understanding of the environmental features and to turn felled tree timber into something long lasting
- orchard creation - to grow fruit, enhance community cohesion and help to replace this lost habitat for the future
- elm reintroduction planting - the planting of elms either bred to be disease resistant or which contain compounds within the bark that makes them unappealing to the beetles which carry Dutch Elm Disease - these trees will replace those lost and provide valuable habitat to butterflies which rely on this tree
- man made habitats - the installation of bird boxes, bug hotels, bat boxes, hedgehog houses and more
