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.

** Side Roads and Compulsory Purchase Orders can be viewed here **

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 trunk road via a grade-separated junction. Technical approval for design has been approved in principle by Highways England and the county council now has delegated authority through a Section 6 agreement with Highways England and the Department for Transport (DfT) to promote the Orders and build the scheme. In addition, archaeological pre-works are now underway and Galliford Try has been identified as preferred contractor.
  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. Archaeological site works are now complete.

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, as well as Highways England, DfT and Network Rail.

Aims and benefits

  • Reduce congestion, disruption and unplanned delays within Grantham Town Centre by improving connectivity and attracting a significant volume of traffic, particularly HGVs and other strategic through traffic
  • Create a safer, more attractive and assessable town centre environment
  • Provide opportunities for growth, including new homes, employment opportunities and community facilities
  • Improve the quality of life for Grantham residents, workers and shoppers by reducing carbon emissions and noise pollution in the town centre.

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 developer contributions, which will be forward funded by Lincolnshire County Council.

Planning permission and public consultation

Planning permission for the GSRR has been granted in respect of the whole of the Scheme consistent with the phasing as set out above. Planning permission for Phase 1 and 2 was granted on 18th August 2010 and Phase 3 planning permission on 27th November 2013: the phase 2 permission was reassessed on 29th January 2016 with a revised permission being granted on 27th May 2016.

Orders were officially promoted in March 2018.
