About the project
Grantham Southern Relief Road
The Grantham Southern Relief Road aims to improve the town's infrastructure and growth.
We will build the 3.5km relief road in three phases:
- Phase One - creation of a roundabout off the B1174.
- Phase Two - the B1174 will join the A1 trunk road.
- Phase Three - link the A52 at Somerby Hill to the new roundabout.
We lead the project, supported by South Kesteven District Council, Homes England and the Greater Lincolnshire LEP. Further support comes from Highways England, the DfT, Network Rail and local businesses.
Aims and benefits
The project aims and benefits are to:
- reduce congestion, disruption, and delays
- create a safer, more attractive and accessible town centre
- provide opportunities for growth
- reduce carbon emissions and noise pollution
Cost and funding
The estimated cost is £102 million and will be funded as follows:
- £11.9m from the Local Transport Board
- £16.1m from the Single Local Growth Fund
- £5m from the Highways England Growth and Housing Fund
The balance of funding will come from developer contributions, which will be forward funded by us. We will also be funding part of the scheme.
