Grantham Southern Relief Road

The Grantham Southern Relief Road (GSRR) is a 3.5km road designed to improve Grantham’s infrastructure, enable economic growth and improve journey times for traffic travelling east to west, north to south and vice versa by linking the A52 at Somerby Hill to the A1.

The relief road will be built in three phases:

  1. Phase One saw the creation of a roundabout off the B1174 and a road along Tollmache Road leading to a second new roundabout. Works were carried out by Fitzgerald Civil Engineering and were completed in August 2016.
  2. Phase Two will join the B1174 to the A1 via a grade-separated junction. A contractor will be officially appointed in 2017 with works due to start during early 2018.
  3. Phase Three will link the A52 at Somerby Hill to the new roundabout off the B1174, crossing the Witham Valley, the East Coast railway line and the River Witham by means of a viaduct/bridge to be constructed. Legal orders are to be published in 2017. A suitable contractor will be appointed following the outcome of the published orders and a competitive tender process. The council is working closely with Network Rail to deliver this phase. 

The project is being led by Lincolnshire County Council and supported by South Kesteven District Council, Greater Lincolnshire LEP (GLEP), Homes and Communities Agency (HCA) and local businesses.

Aims and benefits

  • Reduce congestion in Grantham Town Centre by attracting a significant volume of traffic, including HGVs
  • Improve the town centre environment and provide for growth
  • Provide critical support to a SKDC proposal for a large property development together with employment land at the Southern Quadrant and King 31

Cost and funding

The relief road will cost in the region of £81 million with £33m coming from grant funding, including a Local Transport Board grant of £11.9m; a Single Local Growth Fund grant of £16.1m; and a Highways England Growth and Housing Fund grant of £5m.

The balance of funding is due to be obtained through LCC Capital Funding and developer contributions.

Planning permission and public consultation

A planning application for the project was submitted in March 2013 and granted in November 2013. Details of the planning application can be viewed on the South Kesteven District Council website by using the code S13/0775.
