Carlisle Southern Link Road

As part of developing an improved road network in and around Carlisle, Cumbria County Council are in the process of developing a Southern Link Road scheme for Carlisle. 

The need to improve east to west connectivity has been identified in the Local Enterprise Partnership (LEP)  Cumbria Infrastructure Plan and in Carlisle City Council's recently adopted Carlisle District Local Plan 2015-2030. The link road would be required to unlock delivery of the planned St Cuthbert's Garden Village.

Preferred Route
Following extensive consultation on two route options for the Carlisle Southern Link Road earlier this year, Cumbria County Council have now chosen the Green Route as the preferred route.

The preferred route decision is based on a thorough assessment of evidence using a decision-making framework. The decision-making framework has been applied to the two route options and considers strategic objectives of the scheme, stakeholder feedback including the results of the public consultation and environmental, engineering, economic and deliverability assessments. The Preferred Route Decision Report (PDF 1MB) documents this process, using the evidence prepared as part of the scheme development to recommend a preferred route for the Carlisle Southern Link Road. The decision was approved by the Council on 21 June 2018.


An Environmental Impact Assessment (EIA) has been completed as part of the scheme development, this is summarised in the Environmental Report Non-Technical Summary (PDF 5MB)

Following extensive consultation on two route options earlier this year, the consultation feedback is available in the Consultation Feedback Report (PDF 6MB) and a summary of this in the Consultation Feedback Summary (PDF 3MB).

This work identified a range of reasons why the green route is preferred:

  • The route better enables the delivery of the vision for St Cuthbert's Garden Village
  • It had significantly higher level of public support in the recent public consultation
  • It is considered easier to build with less impact on existing communities
  • The route has a comparatively lower environmental impact.

Following the announcement in March that the project had been successful in moving to the next stage of its funding bid to the Government's Housing Infrastructure Fund, the Council will now work with government officials to develop the Outline Business Case, which will be submitted to the Housing Infrastructure Fund later this year for consideration for delivery funding required to build the road.

The preferred route will also be developed in more detail to reduce its impacts where possible and to incorporate suggestions and amendments received through the consultation process. Further public consultation on a final route proposal would be undertaken in future prior to a planning application, if funding is confirmed.

Project Location

If a Carlisle Southern Link Road is developed in the future, the new road would connect Junction 42 of the M6 with the A595 to the west. The route would include new junctions linking existing radial routes into Carlisle and the Garden Village.

The route would include bridges over two main railway lines and the Caldew and Petteril rivers, a network of footways and cycleways and an extensive programme of landscaping and environmental mitigation.

This 8km long road would provide vital infrastructure to relieve congestion in the historic city of Carlisle and provide the access and network capacity to enable the successful and accelerated delivery of St Cuthbert's Garden Village.

New Component

Project Development

Cumbria County Council, working with Carlisle City Council, have commissioned Carlisle based transport consultants Capita to develop options for a Carlisle Southern Link Road. The team will undertake key surveys and assessments to work towards the development of route options. Public consultation on the route options will take place in early in 2018. A preferred route option will be identified in Summer 2018 and an Outline Business Case will be prepared to assist in securing Government funding to deliver the Link Road.

Project Timescales

The project is dependent on the availability and securing of funding. It is also dependent on legal statutory processes including the planning permission process and the acquisition of land for the route. If challenges faced by funding and statutory procedures can be dealt with effectively the team are currently working to a date for beginning of construction in 2020.

Project Cost and Funding

The cost of the project is unknown at this stage largely because the alignment and location and size of major structures (e.g. bridges) on the route is not yet known. Similar projects have cost between £ 100 million and £ 200 million. Funding for the initial design stages of the project is currently being allocated from Cumbria County Council and Carlisle City Council. The project team is continually looking for funding opportunities from dedicated government funding streams.

Project Environmental Impacts

The impacts on the local environment will be considered within an Environmental Impact Assessment (EIA) which will also inform the project team of features of interest which need to be taken into account. In particular the team will be assessing impacts on the river crossings of the Caldew and the Petteril, listed buildings and the wider landscape.

Following a period of scheme development and assessment two route options were identified for a Carlisle Southern Link Road. From 26 January to 9 March 2018 the County Council undertook a period of public consultation to seek the views of the public, and other stakeholders, in order to inform a decision about which of these two route options should be taken forward to the next stage of the development process.

Green light for green route - Carlisle Southern Link Road plans take next step (22 June 2018)

Following extensive public consultation and technical work the 'green route' has been selected as the preferred option for the new Carlisle Southern Link Road.

Link road moves to next stage in funding bid (21 March 2018) 

Plans for the new Carlisle Southern Link Road received a major boost today with news that the scheme has been selected by Government to move to the next stage of its funding bid.

Public invited to have their say on St Cuthbert's Garden Village and Southern Link Road proposals (26 January 2018) 

Local residents, businesses and organisations are being asked to have their say on proposals to create a new Garden Village on the south side of Carlisle, and the associated development of a new southern link road, as part of public consultations launched by the city and county councils.

Funding bid for southern link road (29 September 2017) 

An application was submitted in September 2017 for the Housing Infrastructure Fund (HIF). The 'HIF' is a £ 2.3 billion Fund which offers funding to local authorities on a competitive basis, for infrastructure to support up to 100,000 new homes.
