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.

Common Croft Lane and Lords Lane, Nether Poppleton – from 1 November for approximately four weeks

From Friday 1 November, Common Croft Lane/Lords Lane will be closed to vehicles, pedestrians and cyclists at the junction of the two roads. 

Traffic management measures will extend approximately 20 metres each side of the junction on Common Croft Lane, and 20 metres into Lords Lane.

The closure will be in place between 7am and 7pm Monday to Friday and 8am and 5pm Saturday and Sunday. Outside of these hours the closure will be removed and the road will be open as usual. We will also open the road if the closure is not needed on a particular day.

Once the closure is in place, a staffed gate will be in place at each end of the closure to coordinate access. General traffic that needs to access Lords Lane will be let through by the staff at the gates.

Emergency vehicles will be permitted access immediately and the road will be cleared for them should they need access.

General traffic wishing to access Common Croft Lane between the junctions of Ouse Moor Lane and West Field Lane will be diverted through Upper Poppleton via West Field Lane, Hodgson Lane, and Main Street. Diversion signage will be in place to direct general traffic around the closure. 

A659, Tadcaster – from 4 November for approximately four weeks

The lane closure on the A659 in Tadcaster was originally due to be in place for two weeks. However, in order to carry out further preparatory works safely and efficiently, there will need to be an extension of the current lane closure and temporary traffic lights on the A659 for a further two weeks

The lane closure, which is close to the junction with Garnet Lane, will be in place between 7am and 7pm every day. The closure had previously been in 24 hours a day.

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.

You may also notice some additional traffic in the area during the closure while our delivery vehicles bring materials to the site.
