CarTraffic Routes


Welcome to our interactive map of the final proposals for HARP.

Using the zoom functions on the left-hand side of the map, you will be able to zoom in and out of specific areas to see more details.

By clicking on the building and car icons on the left, you will see a brief description of each part of the proposal and how this may impact the local area.

In this interactive map you will see outlined:

  • COMPOUNDS – Our main working areas that are needed for constructing the new tunnels and connecting to the existing water network
  • RED LINE BOUNDARY – This is the maximum extent of any of our work. Between the main compounds is a 24 metre corridor within which the new tunnel would be constructed underground. Immediately around our working areas, within the red line boundary would be used for temporary activities including the storage of material and land re-profiling, access and parking, and environmental protection such as surface water lagoons
  • CONSTRUCTION TRAFFIC ROUTES – The way our construction vehicles would travel to access our compounds
  • ROAD ALTERATIONS – Temporary road alterations along the construction traffic routes to facilitate the safe use of the local roads during our work

These plans were designed following a consultation that engaged thousands of people across Cumbria, Lancashire and Greater Manchester. Thank you to everyone that helped shape the future of water services in the North West.


  • Most of our work takes place below the ground with little long-term above ground impact
  • Once the Tunnel Boring Machine sets off it will run 24-hours a day. This would require some activities to be carried out during the night within the site compound area
  • All construction traffic would be limited to normal working hours which are between 7am – 7pm Monday to Friday and 7am – 1pm on Saturdays
  • During night-time working special lighting would be used that is directed towards working areas
  • Where there are public rights of way that interface with our temporary working areas, we would use crossing points to ensure they remain open

Newton-in-Bowland compound (view in map)

  • This would be our main working area for the Bowland tunnel and where we would start construction of the tunnel section
  • We would be working here for around 7 years
  • This compound site would be split across Newton Road with our site cabins, material storage and car parking areas to the south of the road
  • We would install a temporary bridge over the portion of the Biological Heritage Site within the footprint of our proposed works to reduce the impact on it
  • A temporary bridge would be installed over the River Hodder to create a haul road so that our vehicles can avoid travelling through the village of Newton-in-Bowland

Lower Houses compound (view in map)

  • This is where the Tunnel Boring Machine would finish constructing the Bowland section and be taken from the ground
  • Tunnel construction would mainly be done from the Newton-in-Bowland compound, reducing activity on this site
  • We would work here during our normal hours, with a period of around eight weeks where we would need to work during the night
  • Surplus material arising from the construction of the tunnel shaft would be kept on site, reducing the number of vehicles using local roads

Traffic Routes

Lancaster (view in map)

  • Access to the site would be taken from Junction 34 of the M6, along the A683 through Wray, Tatham, Wennington and Bentham, along Eskew land and Long Lane
  • Typically we expect there to be between four and eight construction vehicle movements on this route each hour. This may peak up to 10 movements per hour.
  • From Long Lane at the junction of Fairheath Road, a one-way system would be employed to limit the potential for conflicts between construction traffic travelling in opposite directions
  • Some of the one-way system would need to be followed by all road users in order to avoid conflicts with large vehicles
  • Our construction traffic access proposal would avoid Main Street in Wray. There would be some occasions during where we would require large vehicles to use Main Street and travel up Helks Brow. We expect this to take place on 18 weeks over the construction period and will include temporary parking restrictions
  • We would notify anyone who would be affected by road alterations in advace

Wray satellite compound (view in map)

  • We would use a smaller satellite compound outside of Wray as a vehicle holding area
  • This would reduce the number and control the timing of all vehicles travelling to the Lower House compound
  • Access to this would be from the B6480 Hornby Road

Ribble Valley (view in map)

  • Many of the vehicle movements for this work would be to take surplus material from the construction of the new tunnel off our site. This surplus material would be taken to Waddington Fell Quarry, reducing the number of vehicle movements
  • The increase of vehicle movements is expected to be around 10% more than usual. Most of those additional movements would be large construction vehicles
  • Most of the vehicle movements would take place when the Tunnel Boring Machines are constructing the Bowland tunnel and the Marl Hill tunnel, which need to be done at the same time. This work would last for around two years
  • Below is an indication of the additional vehicle movements needed to support our works relating to different parts of the road network;
    • Between the A59 and our access to the Braddup compound, typically between 3 and 9 vehicle movements per hour with a peak averaging up to 16 per hour
    • Between the access to the Braddup compound and Waddington Fell Quarry, typically between 5 and 15 vehicle movements per hour with a peak averaging up to 25 per hour
    • Between Waddington Fell Quarry and the access to the Bonstone compound, typically between 10 and 20 vehicle movements per hour with a peak averaging up to 35 per hour
    • Between the access to the Bonstone compound and the access to the Newton-in-Bowland compound, typically between 5 and 15 per hour with a peak averaging up to 30 per hour
  • Our planning application will include two route options for access to the Bonstone and Braddup compounds for the Marl Hill tunnel. Ribble Valley Borough Council, in consultation with their statutory and non-statutory consultees, will determine which of these two options would be adopted for this work

Additional work to support construction traffic access

  • A series of road alterations are proposed to ensure the road network can safely accommodate larger construction vehicles
  • We may use other traffic management too, such as speed restrictions and traffic lights
  • Road alterations would involve junction modifications, creation of access points to our site, and widening of the road
  • All works which fall within the highway owned land would be retained by agreement
  • Any modifications which encroach on third-party land would be reinstated
