A40 Tetsworth embankment repair work

Work started on 22 June on the A40 at Tetsworth near Attington Stud.

Diversion via Thame

Work began on 22 June for around 25 weeks, subject to any bad weather or unforeseen circumstances arising during construction. There will be a signed diversion via Thame.

At this location the A40 serves as an emergency diversion route for any incidents on the adjacent M40 and the stability of the road edge and footway has been monitored for a number of years.

To help ensure the route is safeguarded for the future, we are investing £2.1m for these planned stabilisation roadworks.

Work includes:

  • widening and stabilising of the highway embankment
  • carriageway reconstruction
  • drainage improvements
  • kerbing and footway reconstruction
  • hedging
  • fencing

Next steps

Construction of the embankment stabilisation roadworks started on 22 June and are expected to last for around 25 weeks (mid December). 

Diversions and access

Access for pedestrians and dismounted cyclists will be maintained. Staff will be positioned at the start of the closure to ensure the safety of the public and workforce. We ask that you give them your full support whether you are a pedestrian, cyclist or motorist.

Construction traffic will only approach the site from the east M40 Jct 6 Lewknor or B4012.

For safety reasons a signed diversion route (pdf format, 1.7Mb) via Thame will be provided.
