Thus, in 1756 when the Colsterworth to Bourne road was turnpiked,(9a) the toll road which was to become the A151 began at the crossroads in Colsterworth, further west than it now does, though the first toll gate noted by the 1824 Ordnance Survey map was about three kilometres from there. When the Colsterworth bypass was built, its southern half was placed virtually on the Ermine Street line so that now, while the A151 still begins at the A1, it is not at the old Great North Road but at Ermine Street, on the chalky till soil that we start our journey. Bourne Road, Colsterworth, the section removed from the A151, remains part of the B676, the road which leads westwards, towards Melton Mowbray.(10)
