M4 Junction 16 Traffic Notice

M4 Junction 16 Traffic Notice

Work will take place overnight from 21.00 hrs on Monday 22nd May to 06.00 hrs on Tuesday 23rd May (subject to weather conditions).

To carry this out safely, we need to reduce the westbound M4 to single lane running and fully close the westbound exit slip road during the above times.  While the slip road is closed, the official signed and agreed diversion route will be:

  • Continue along the M4 to junction 17 (Chippenham), then exit the motorway
  • Travel around the roundabout and get back on the M4 eastbound carriageway
  • Exit the motorway at junction 16 and continue to original route

Although the above work is not expected to cause significant disruption, we are still encouraging drivers to check before they travel and allow extra time for their journeys.
