Bayley-Hazen Military Road

The Bayley–Hazen Military Road was a military road that was originally planned to run from Newbury, Vermont, to St. John's, Quebec, not far from Montreal. 54 miles (87 km), running from Newbury to Hazen's Notch near the Canada–United States border, were constructed between 1776 and 1779 during the American Revolutionary War. Portions of the road's route are used by modern roads today.

The road is named for the principal proponents of its construction. Jacob Bayley and Moses Hazen were among the founders of Newbury and nearby Haverhill, New Hampshire, and Hazen also had property interests at St. John's. The idea for the road featured prominently in several proposals (promoted primarily by Hazen to George Washington and the Second Continental Congress) for invasions of Quebec by Continental Army forces following the failed 1775 invasion.

After hostilities in the French and Indian War ended in 1760, several veterans of that war founded the communities of Haverhill and Newbury on either side of the Connecticut River in the far north of the British province of New Hampshire. The land on the west side of the river was the subject of disputes between New Hampshire and the province of New York, and was known then as the New Hampshire Grants; this territory eventually became the state of Vermont.
