A303 road marking and stud replacement – Ilminster Bypass
We are renewing road markings and replacing road studs along stretches of the A303.
We’ll be working on weeknights (8pm – 6am). This is when there is less traffic on the road. The A303 will be open as usual during the day and at weekends.
Please be advised that we will be returning to the Ilminster Bypass next week to complete the outstanding road marking and stud works. Unfortunately, due to adverse weather conditions during our previous visit, we were unable to complete these works in full.
