Junction 17 Signals Live

Junction 17 Traffic Signals now live

The newly installed traffic signals on junction 17 of the M4 are now on and operating. The traffic signals will help to keep traffic flowing across this busy junction and reduce the backing up of traffic onto the M4 itself. The new signal heads are situated at the top of both the exit slip roads and will work in connection with the signals on the gyratory to keep traffic moving safely.

FAQs

The M4 junction 17 improvements scheme intends to reduce existing congestion on the M4 off-slips and prevent traffic from backing up onto the M4 motorway. The scheme seeks to introduce traffic signals on to two of the arms (the M4 off-slips in both directions) and the corresponding circulatory carriageway. Close

The main works contract is currently expected to commence around August 2017 and will take approximately 6 months to complete.

The scheme cost of £1.46m will be funded by Highways England (who operate the M4) and the Local Growth Fund, which is administered by the Swindon and Wiltshire Local Enterprise Partnership.

Close

A policy of improvements to junction 17 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 for viewing from the Swindon and Wiltshire Local Enterprise Partnership.

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.

Appropriate and safe traffic management measures will be set up to reduce the impact of scheme construction as much as possible. Inevitably, however, there will be some disruption to traffic especially at peak times.

We have designed a traffic signal control system that controls traffic on the gyratory and the stop lines at the top of the offslips. The reason for this part signalisation scheme was to reduce the extent to which traffic backed up along the offslips onto the motorway mainline at peak times, reducing the number of accidents occurring there.
