Another long section remains, now the A15, running north out of Lincoln, past RAF Scampton and Caenby Corner, past Kirton in Lindsey at grid reference , and continuing almost to the Humber at Winteringham. Before the diversion was made round the extended runway at Scampton, with a very slight diversion at Broughton, it was possible to travel about 33 miles, from the Newport Arch, the Roman north gate at Lincoln, to the Parish of Winteringham along a road so slightly curved as to be regarded as straight.
