A40 Over Roundabout Improvement Scheme

The A40 Over Roundabout is located to the northwest of Gloucester and is the primary point of entry into the city for vehicles travelling from the west.

Highways England carried out the first phase of the planned improvement works for this roundabout. That scheme was called the A40 Over Roundabout western approach widening and completed in March 2015. This consisted of widening the A40 eastbound approach to three lanes to allow a dedicated right turn lane, and also widening the roundabout carriageway on the northern side. A pedestrian crossing was moved to a better location and the lighting was improved within the vicinity of the works.

About the new scheme

The following junctions along the route have been identified for improvement.

  • A417 north: widening of the southbound approach to the roundabout entry to provide three lanes at the junction stop line.
  • A40 east: widening of the westbound approach to the roundabout entry to provide three lanes at the junction stop line.
  • A40 Roundabout - general: The addition of a third circulatory lane within the roundabout.

Purpose of the scheme

The overarching goal is to provide a free flowing link for traffic along the currently heavily congested A40 roundabout.    

The key objectives have been identified as:

  • Reduce journey times, for all users as well, on the A40 between Highnam Roundabout / Longford Roundabout / Gloucester City Centre.
  • Improve journey time reliability on the A40 between Highnam Roundabout / Longford Roundabout / Gloucester City Centre.
  • Improve the connectivity and capacity of the strategic road network between the Forest of Dean and Gloucester / Cheltenham / Tewkesbury / the M5.

The current programme for the A40 Over Roundabout scheme is as follows:

  • Business case submission - October 2016
  • Business case approved by LEP - December 2016
  • Meet the contractor event - 23 April 2018
  • Construction start - 30 April 2018
  • Construction end - September 2018

Construction work is now underway

Work started on 30 April and will last for 18 weeks, finishing in September 2018. 

There will be no lane closures between 7am – 9:30am and 3:30pm – 6pm throughout the scheme.

All daytime works will be completed using lane closures with the roundabout remaining open. Delays are expected but access will still be possible.

Although some weekend working may be necessary, the majority of the work will take place on weekdays. Resurfacing works were carried out at the roundabout over the weekends of  4 - 5th and 11 - 12th August and were finished on Saturday 18th August.

Overnight piling works have now finished

Here is a video update on the scheme from Cllr Vernon Smith, cabinet member for highways:
