Junction improvement programme

Project information

A30 Crooked Billet roundabout

Work began in May 2020, with a current focus on the two main islands in the centre of the roundabout, with drainage and excavation works under way. Our teams have recently changed from daytime working to overnight working, and works will now be carried out in shifts between 8pm and 5.30am, Monday to Friday.

Further footway, cycleway and carriageway improvements are planned.

The overall progress of the junction 23 improvement scheme is now over 80% complete. Work on the M25 anti-clockwise exit slip road is now complete, and all required sheet piling works have now been carried out.

Carriageway resurfacing and the installation of new street lighting and traffic signals have commenced on the A1 southbound entry slip road and the junction 23 gyratory.

Work on Bignells Corner has been temporarily suspended and is currently planned to resume in late November.
