Narrow lanes now in place - A350 Chequers roundabout
As part of the ongoing works on the A350 around Chippenham further traffic management has now been introduced. Narrow lanes will be in place around Chequers roundabout and north of Cepen Park roundabout. The increased traffic management will allow for safe working space when constructing the new carriageway.
A350 Traffic Management
The improvements to the A350 Chippenham bypass will involve:
- Widening the A350 to dual two-lane between Badger and Brook roundabouts, and between Cepen Park South and Chequers roundabouts.
- Additional widening of the A350 for approximately 250 metres north of Cepen Park South and 250 metres immediately south of Chequers, to allow for suitable merge lengths back to single lane running and to allow for two lanes on the A350 approaches to the roundabouts.
- As part of the widening to the south of Chequers, a new formal segregated layby will be provided on the northbound carriageway to replace the existing unsegregated layby.
- Widening the A4 Bath Road westbound approach to Chequers, along with widening the A4 westbound exit, providing two lanes across the junction for A4 westbound traffic.
The main works contract is currently expected to be in place for 13 months (July 2017 to August 2018).
The scheme cost of £7.1m is funded via the Local Growth Fund, which is administered by the Swindon and Wiltshire Local Enterprise Partnership (SWLEP).
These further dualling works funded through the Local Growth Fund, will complement the first two phases of dualling works that have been undertaken during 2014 and 2015. Both of these schemes were designed to address issues at specific locations, within the funding available at the time, and have been jointly funded by Wiltshire Council and devolved funding streams.Close
A policy of selective improvements to the A350 has been included in the council’s development plans, including the current Wiltshire Core Strategy for a number of years. These have been subject to extensive public consultation.
Given the above and the fact than no planning permission is required for the scheme, no formal public consultation has been undertaken.
The full business case is available from the Swindon and Wiltshire Local Enterprise Partnership.Close
The congestion and safety issues which the schemes are designed to address are a reality now and will worsen with increasing traffic and economic and development growth.
Jointly procuring and delivering the schemes provides efficiencies and better value for money.Close
The council has improved the A350 Chippenham bypass as and when funding has become available. Often this means that we have to bid for limited funding to deliver schemes in a prescribed time frame.
Funding for the latest schemes is a result of a successful bid to the Government’s Local Growth Fund (as announced in July 2014) which is administered by the SWLEP.
A further funding bid for dualling between Chequers roundabout and Lackham roundabout was submitted in July 2016 as part of a third round of Local Growth Deals. Unfortunately, the bid was not successful in achieving an allocation.
Dualling the section between the Bumpers Farm roundabout and Cepen Park South roundabout has not been progressed at this time due to funding and value for money considerations.Close
Current Noise levels were measured and future Noise levels forecast as part of the feasibility study. Were predicted noise levels found to be excessive, the scheme would be unlikely to receive DfT funding, or design measures would have been imposed as a condition of funding. This was not deemed to be an issue and so no special measures have been implemented.
There will be a concrete safety barrier separating the proposed northbound and southbound carriageways. This is expected to limit the noise to which local residents are subjected to no more than that currently experienced
Furthermore, 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 surfaces with coated chippings.
The posted speed limit is a national limit, which is currently 60mph. Once the new road works have been completed and in operation for a few months, the need for any modifications to aid the flow of traffic may then be considered.
