The A15 is a major road in England. It runs north from Peterborough via Market Deeping, Bourne, Sleaford and Lincoln along a variety of ancient, Roman, and Turnpike alignments before it is interrupted at its junction with the M180 near Scawby. The road restarts 10 miles (16 km) east, and then continues north past Barton-upon-Humber, crossing the Humber on the Humber Bridge before terminating at Hessle near Kingston upon Hull.
