Since at least the 15th century, Stony Stratford was an important stop on the road to Ireland via Chester, becoming quite rich on the proceeds in the 16th century. In the stage coach era of the 17th and early 18th centuries, it was a major resting place and exchange point with the east/west route with coaching inns to accommodate coach travellers. Traffic on Watling Street and the consequent wear and tear to it was such as to necessitate England's first turnpike trust, from Hockliffe to Stony Stratford, in 1707. In the early 19th century, over thirty mail coaches and stagecoaches a day stopped here. That traffic came to an abrupt end in 1838 when the London to Birmingham Railway (now the West Coast Main Line) was opened at Wolverton – ironically, just three years after the bridge over the Ouse had been rebuilt. Wolverton railway works provided an important source of employment in the town, with the Wolverton and Stony Stratford Tramway being built to serve the workers. With the arrival of the motor car, the town's position on the original A5 road made it again an important stopping point for travellers.
