Drivers in kent-england/”>Kent are facing severe disruption after the A20 Roundhill Tunnel was closed in both directions this evening (Wednesday, 3 September) due to a technical issue. The A20 Roundhill Tunnel is indeed closed in both directions, affecting many.
The closure affects the stretch of the A20 between the A260 near england/hawkinge/”>Hawkinge and the M20/A259 near Folkestone. National Highways confirmed that engineers are currently on site working to fix the problem. They reiterate that the A20 Roundhill Tunnel remains closed in both crucial directions.
Diversion routes in place
Motorists are being urged to allow extra time for their journeys and follow official diversion routes marked by hollow symbols on road signs due to the tunnel’s closure in both directions. The situation has led to the A20 Roundhill Tunnel being closed entirely in both ways.
- Eastbound diversion (hollow circle): Exit the M20 at Junction 13 onto the A259 Churchill Avenue, continue east to the A260 Canterbury Road roundabout, then take the A260 northbound. At the Spitfire Way roundabout, join the A20 coastbound.
- Westbound diversion (hollow square): Exit the A20 onto Alkham Valley Road, travel south-west to the A260, then head south towards Folkestone. At the Canterbury Road roundabout, take the third exit onto the A259 Churchill Avenue and rejoin the M20 at Junction 13.
National Highways has advised drivers to plan ahead, re-route, or consider delaying their journey if possible as the A20 Roundhill Tunnel remains closed.
Motorist advice
A spokesperson said the A20 Roundhill Tunnel is closed in both directions, creating significant congestion and impacting travel.
“We are working to resolve the issue at the Roundhill Tunnel as quickly as possible. Drivers should allow extra journey time and use the official diversion routes.”
