CARRIAGEWAY REPAIRS ON THE M8 JUNCTION 4 WESTBOUND ON-SLIP

November 11, 2026

  • Overnight slip road closure Friday 20 November 2026

The slip road onto the westbound M8 at Junction 4 (East Whitburn) will be closed for carriageway repairs between 20:00 and 06:00 on the night of Friday 20 November.

A signed diversion route for traffic wishing to join the M8 westbound at Junction 4 will be in place via the M8 eastbound to turn at Junction 3A (Starlaw interchange) and return westbound. This will add approximately 7 minutes and 6.3 miles to affected journeys.

Access for emergency vehicles will be maintained at all times.

Relevant stakeholders have been consulted in advance to make them aware of the plans.

Tommy Deans, BEAR Scotland’s South East Network Manager, said: “It’s necessary to close this slip road at M8 Junction 4 to carry out repairs to the carriageway.

“We’ll do this at night to minimise disruption, however please plan ahead and allow extra time for the diversion if you need to use this route.”

All works are weather dependent and subject to postponement in the event of adverse conditions.
