MD 267, which follows the path of the Old Post Road between Baltimore and Philadelphia, was constructed as a modern highway along that main line in 1915. The highway was bypassed by what is now MD 7 in 1921 to avoid a pair of dangerous bridges across what is now Amtrak's Northeast Corridor railroad line.
