5th May 2021 | Local News

Phase Three of the Grantham Southern Relief Road is underway.

Work on the final section of the £102M road began last month, as previously reported by Nub News.

The final phase of the relief road will link the A52 at Somerby Hill to the B1174, crossing the Witham Valley, River Witham and East Coast railway line with a new viaduct/bridge.

Work on the relief road's second phase, which will join the B1174 to the A1, is currently underway and expected to be complete later this year.

When opened, the whole Grantham Southern Relief Road will stretch for 3.5km, linking the A52 at Somerby Hill to the A1.

Lincolnshire County Council expects to have the entire relief road open by the end of 2023.

In its monthly progress report, the county council announced the following:
