Ongoing restrictions 

From 5 January 2026 to 30 April 2026, new temporary traffic signals and pedestrian diversions will be in place as follows:

• 3-Way Traffic Lights: Temporary signals will be positioned on the B4022 (just south of the bridge), on South Leigh Road, and at the end of the westbound off-slip.
• Bus Stop Relocation: The current bus stop will be temporarily moved. A new stop will be installed approximately 75 metres from the existing one.

Pedestrian Access: For pedestrians, a dedicated pedestrian route will be maintained through the works area

From 10 February 2025 until the end of construction, 

• the speed limit on the A40 within the scheme extents will be temporarily reduced to 50mph and the B4022 within the Scheme extents will also be temporarily reduced to 30mph.
• Lane 1 of the A40 within this project area will be closed in both directions. Other lanes will remain open to traffic.

Appropriate traffic signs are displayed to indicate when traffic measures are in force. The alternative route for traffic affected by any closure is via signed diversion route.

Any major construction project that modifies an existing highway will cause disruption. We are doing all we can to mitigate disruption to the greatest extent possible through phased implementation and speed limit reductions for the safety of our road network users and our workforce. We appreciate your patience as these improvements are carried out.
