Preparatory works: traffic management

Preparatory works for Yorkshire GREEN, which will enable us to begin the main works in early 2025, have now started.

Over the next few weeks there will be some road closures and other traffic management in place to allow us to carry out some of these works.
Some of the preparatory works we need to undertake include:

• trimming hedgerows to improve sight lines for vehicles
• widening the mouths of access tracks in fields where they meet the roads (known as bellmouths)
• constructing temporary roads to enable our vehicles to access fields
• erecting fencing around site boundaries
• installing signage to assist the navigation of vehicles accessing the construction site
• preparing soil bunds, which are banks of soil that reduce the visual impact of the works and preserve the integrity of the topsoil
• setting up the site compounds. 

To allow us to do this work safely, there will be some traffic management and road closures in place over the next few weeks.

You can view the exact locations of the traffic management and road closures in place on our interactive map.

Rawfield Lane, between Monk Fryston and Fairburn – from 1 November until 20 December 

The lane closure on Rawfield Lane was originally due to be in place for three weeks. However, in order to complete our preparatory works safely and efficiently, there will need to be an extension of the current lane closure and temporary traffic lights for a further four weeks.

The lane closure, which is between the junction with the A63 and the entrance to Monk Fryston Substation will be in place between 7am – 6pm Monday to Friday. The lane closure was previously in place 24/7.

Temporary traffic lights will remain in place to maintain two-way traffic flow.

Outside of these hours, the lane closure will be removed and the road will be open as normal. We will also open the road as normal if the closure is not needed on a particular day.

Tockwith Road, Long Marston – from 9 December until 20 December

From Monday 9 December, Tockwith Road will be reduced to one lane of traffic at the junction with Moor Lane, near the Battle of Marston Moor Monument, until Friday 20 December.

The lane closure will be in place between 7am and 7pm Monday to Friday, and temporary traffic lights will be in place to maintain two-way traffic flow.

Outside of these hours, the closure will be removed, and the road will be open, though it will be slightly narrower. We will also open the road if the closure is not needed on a particular day.
