Recent rebuilding of the A1 road junction at Woolsthorpe-by-Colsterworth in 2008 has included construction of a grade-separated road crossing in place of the disused railway bridge that was part of the High Dyke branch, a mineral railway used to export iron ore between 1916 and 1973 [REF].
There is a roundabout adjacent to Prince William of Gloucester Barracks east of Grantham, but all other junctions are conventional grade-level crossroads or T junctions.
