A38 Ivybridge to Marsh Mills – westbound resurfacing works
We’re resurfacing the westbound A38 between Ivybridge and Marsh Mills. This will maintain and improve safety for everyone using the road, and reduce the need for any unplanned closures.
The works will be carried out in three phases.
We’ll be working weeknights (Monday – Friday between 8pm and 6am) when there is less traffic on the road.
During the day and at weekends, including over the August Bank Holiday weekend, the road will be open as usual.
Where are we working and when?

- Phase one – A38 westbound between Smithaleigh and Voss Farm
Works will start on Monday 30 June and will take us up to two weeks to complete.
- Phase two – A38 westbound between Wrangaton and Ivybridge
Works will start on Wednesday 09 July and will take us up to two weeks to complete.
- Phase three – A38 westbound from Deep Lane to Marsh Mills
Works will start on Friday 18 July and will take us up to six weeks to complete.
