 In 1762 Hazen 's brother John settled Haverhill , New Hampshire , in the far north of that province on the east side of the Connecticut River , and in 1764 Jacob Bayley settled Newbury , in what is now Vermont , across the river from Haverhill . Hazen had shares in both of these settlements ; he also acquired land west of the Connecticut River in what is now Bradford , Vermont . It was at this time that the idea of constructing a road from there to Saint @-@ Jean was first raised ; this idea surfaced again during the American Revolutionary War , when George Washington authorized construction of what became known as the Bayley Hazen Military Road .
