An incredible new £148million road and bridge is being built with the top to end traffic chaos in a UK town.

The Grantham Southern Relief Road, also known as the Grantham Bypass, will be a 3.5km road to the south of Grantham to ease traffic through the town.

It will go from the A52 and B1176 to the east of Grantham, across Whalebone Lane and the B1174 to meet the A1 to the south.

It is being built in three phases - the creation of a roundabout off the B1174, joining the B1174 to the A1, and linking the A52 to the new roundabout.

The first two phases have been completed, with phase three currently underway. Work started on the relief road in September 2015, after being granted permission to begin phases one and two in August 2010.

Phase one was completed a year later in August 2016 but works on phase two didn’t start until October 2019. Phase three began in April 2021, while two was ongoing. The second phase was finally finished in December 2022. 

Lincolnshire County Council and its partners are aiming for the road to be fully built and open by 2025.

The project aims are to reduce congestion, disruption, and delays; create a safer, more attractive and accessible town centre; provide opportunities for growth; and reduce carbon emissions and noise pollution.

The estimated cost is £133 million and is being funded by the Local Transport Board, the Single Local Growth Fund and the Highways England Growth and Housing Fund.

In addition to the £133 million, the bridge extension is expected to cost a further £15 million.

Lincolnshire County Council is leading 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.
