Update on preparatory works

Preparatory works for Yorkshire GREEN have progressed well since they began in autumn 2024 and we would like to thank you for your patience and cooperation while we have been undertaking these works. 

We are pleased to report that the National Cycle Network Route 65 diversion between Overton Road and Station Lane is now open and will remain in place throughout the construction period.

We will carry on with our preparatory works for the first few months of 2025. These will enable us to begin the main works in spring 2025.

Upcoming works in 2025

We will continue with our preparatory works for the first few months of 2025, our preparatory works will include:

• finishing our bellmouths and access tracks
• installing pylon foundations
• clearing vegetation to improve sight lines for vehicles
• widening a section of Overton Road to enable access for large vehicles
• completing the Overton Substation and Monk Fryston Substation compounds.

Our team are doing all they can to minimise any inconvenience caused by our works, however, given the nature of the activity, it is likely that there will continue to be some disruption in areas we are carrying out our works. 

Upcoming and existing traffic management

To ensure the safe and timely completion of our preparatory works, we will need to put some traffic management measures in place around the areas we are working in. You can also view upcoming and existing traffic management on our interactive map.

These include:

Overton Road, Overton, York – Monday 13 January until Monday 3 February 2025

To facilitate access for larger delivery vehicles to the Overton Substation, we will need to widen a small section of Overton Road between Station Lane and the Overton Substation site. Once complete, this widening will be permanent.

This work will require road closure, which will be in place between Monday 13 January and Monday 3 February 2025.

The road closure will be in place 24/7 for the duration of the widening works and a signed diversion route will be in place via Stripe Lane.

An airlock system will be in place for large vehicles which are unable to get under the railway bridge on Stripe Lane, with a staffed gate at each end of the closure to co-ordinate access.,

Emergency services will be let through immediately and any traffic along the road will be cleared to facilitate access.

A659 Tadcaster, near Garnet Lane – Monday 27 January until Sunday 23 February 2025

To enable us to complete a bellmouth and access track, there will be a lane closure on the A659, Tadcaster between Monday 27 January and Sunday 23 February 2025. 

The lane closure will be in place near to the junction of Garnet Lane. Temporary traffic lights will be in place to maintain two-way traffic flow. 

The lane closure will be in place at all times. 

On Friday 7 February 2025 at 5pm, the lane closure will be removed until Monday 10 February 2025 to help facilitate an event happening nearby. 

Stone deliveries in Overton and Monk Fryston

If you live in the Overton and Monk Fryston areas, you may have already noticed vehicles in the area delivering stone to our compounds. From Thursday 2 January 2025, the number of these deliveries to our site will increase for a period of between six to eight weeks. To minimise inconvenience, we are: 

• instructing delivery drivers to access our sites via approved routes and follow directional road signage
• phasing our deliveries and holding delivery vehicles on site to reduce the number of vehicles on the roads. 

Given there may be some delays as a result of more vehicles on the road, we would encourage you to plan your journeys ahead and/or use an alternative route to make sure you can reach your destination on time. 

If you experience any issues while stone deliveries are ongoing, please get in touch with our Community Relations Team.
