HS2 – Notice of road closure for A361, final tie-in works

Message from EKFB on behalf of HS2.

Dates have now been confirmed for the road closures required for the A361 tie-in works.  This will involve two phases of road closures.

Phase one – weekend closure between the roundabouts on the A361, Chipping Warden bypass on 8pm Friday 19 September until 6am Monday 22 September. This will complete the utility connections.

Phase two – two-week road closure, with no access between Chipping Warden and Byfield from 8pm Monday 22 September to 6am Monday 6 October, 24 hours a day.  During this time, we will be working at 24 hours a day to complete some of the activities, please be aware that some additional lights will be required and you may hear noise from machinery later than usual. This will be closely monitored, but if you have any concerns, please contact the Helpdesk.

This will complete the road realignment, and the road will reopen over the tunnel. Please take extra care when using the new road layout.

Please find full details in the attached notice.
