 The post road followed (present day) Village Street through Millis (part of Medway until 1885).In the early 19th century, the Hartford and Dedham Turnpike was built (now Rt 109), a straight route built through the Great Black Swamp, and up a large hill in the center of town.The original Post Road in Millis followed Village St from Medway, crossing current Massachusetts Rt 109, and then following the current Dover Road to the location of a series of Bridges over the Charles River leading into Medfield.
