Work begins 12 August for 20 weeks
Oxfordshire County Council is preparing to begin construction on the Harwell Campus Entrance project. The project consists of improvements to Northbound A4185 at Thompson Ave including resurfacing, drainage, utilities, traffic signals, street lighting, and electrical works.
The Council has been successful in obtaining City Deal funding from the Department of Transport for a number of schemes in the Science Vale area. One of these is to improve access to Harwell Campus, which is a strategically important part of the Science Vale UK Enterprise Zone. The site is subject to continuing, ambitious development and improved access is required to complete these developments.
The current give-way junction between the A4185 Newbury Road and Thompson Avenue will be insufficient to cater for the additional predicted trips into and out of site. Initially, a three-arm roundabout was proposed to improve the junction, however, subsequent design work established that the construction costs of a roundabout would have been prohibitive due to significant utility diversions and third-party land acquisition.
It is now proposed that this junction off Thomson Avenue will be upgraded through the provision of new traffic signals. This new design will provide greater capacity to accommodate the predicted future housing and employment growth in the Science Vale area and is the most cost-effective option.
Preparatory efforts are currently underway with a minimal impact to the traveling public and nearby stakeholders. 2-way lights are being used under manual control during off-peak hours to accommodate the preparatory efforts.
Construction is planned to commence on the 12th of August 2019 lasting for 20 weeks. During this time the A4185 will be under 2-way lights. In an effort to reduce the impact to the traveling public and nearby stakeholders the 2-way lights will be manually controlled between the hours of 7:00 AM and 7:00 PM.
