FAQs on improvements to A350 around Chippenham
Improvement works on the A350 West Cepen Way will started on 6 July 2015 and are expected to take an estimated 38 weeks, finishing in Spring 2015. The scheme will improve the capacity between Bumpers Farm Roundabout (A420) and Brook Roundabout. It includes improvements to the A350 approaches at both Bumpers Farm Roundabout and Brook Roundabout.Close
Bumpers Farm Roundabout has long been identified as a frustrating bottle neck for drivers with lengthy traffic queues, particularly at peak times. The main objective of the improvement work is to reduce peak time congestion and improve overall journey times along the A350.Close
The estimated cost of the scheme is £3.4 million and jointly funded by the Local Transport Body, Local Enterprise Partnership and Wiltshire CouncilClose
No. The decision to make improvements in the vicinity of Bumpers Farm and Brook Roundabouts is based solely on the need to improve capacity and reduce journey times.Close
While the primary focus has been on the heavier trafficked A350, we have not ruled out capacity improvements to these sections also.Close
A Hot Rolled Asphalt (HRA) surface course with a high stone content has been specified. High stone content surfaces provide quieter running surfaces than traditional HRA with coated chippingsClose
The overall number of pedestrian movements at the crossing location is considered low. Controlled facilities such as signalised crossings are typically used where pedestrian movements are moderate to high (over 50 per hour during the peak period) and where there are insufficient gaps in the traffic in which pedestrians can cross. The proposed crossing is designed as a dual stage facility which will allow pedestrian to cross the A350 via a central refuge in two separate stages. Provision will also be made as part of the proposed works to allow for a future upgrade to a controlled facility should conditions dictate.Close
For safety reasons it will be necessary to temporarily close the footpath during the proposed works and a signed diversion will be in operation. The footpath will be reopened to pedestrians when it is safe to do so. In the longer term we are currently examining options to provide an improved footpath route across the A350 without using the culvert.Close
Drivers should see journey times improved even further on the A350 around Chippenham as Wiltshire Council carries out starts £3.4m improvement work.
Work to improve traffic flow started on 6 July, and although there will be some disruption on what is a very busy route, the council is doing everything it can to minimise this by avoiding the use of traffic lights.
During construction a 30mph limit will be in place to ensure the safety of the site staff, and will allow the road to be kept open to two-way traffic throughout. There will be a series of overnight closures to allow specific items of work to be carried out safely.
The work is due to be finished in early 2016.
Philip Whitehead, cabinet member for highways, said: "This is a very important route, one which has typically been a bottleneck. Although there will be some disruption while the work is ongoing, the outcome will improve journey times and ease the congestion around this area. Wiltshire is already very well connected in terms of transport links and this investment will bring economic benefits to the county as Wiltshire becomes an even more appealing place for businesses looking to relocate to."
Currently restrictions to the capacity of the A350 at Chippenham create congestion on the approaches from the M4 Junction 17 and Chippenham Bypass West Cepen Way. This causes significant delays during peak hours for traffic accessing the town and the A350 corridor through the county.
The improvement to the A350 at Chippenham will see:
- The dualling of the A350 in both directions on West Cepen Way between Bumpers Farm Roundabout (A420) and Brook Roundabout
- Improvements to the A350 on both approaches to Bumpers Farm Roundabout
- Improvements to the A350 on both approaches to Brook Roundabout
The scheme will be part-funded with money from a successful bid to the Local Transport Body, through the Swindon and Wiltshire Local Enterprise Partnership (SWLEP).
The budget for the project is £3.356m, and it will deliver the benefit of less congestion and greater journey time certainty and savings.
There are outline plans to begin work to dual the remaining sections of the A350 from Badger Roundabout (Morrison) to Checkers Roundabout (A4) in 2017. More information will be released on this nearer the time.
