America’s first “interstate” highway was built to link Boston to New York City. The 17th century Boston Post Road is often overlooked in the city’s early history, but it marked the earliest and one of the most ambitious attempts to knit the fragmented English colonies of North America into a single, cohesive entity. From Boston’s first post office, which accepted only overseas letters, to the post riders who braved “mountainous passages” and roaring rivers, this primitive road network was the original interstate, forged not just for convenience, but for the survival of the British colonial project.
In this episode, we’ll explore how the Boston Post Road evolved from an indigenous trade route into the King’s best highway, a crucial artery for colonial and early federal correspondence. We’ll trace the routes of the upper Post Road through the wilderness of Central Massachusetts and Connecticut and the coastal lower Post Road that shaped the roads and transportation networks of modern New England. Along the way, we’ll uncover the stories of the people who marked the miles, from wealthy landowners like Paul Dudley, to determined travelers like Madam Sarah Kemble Knight, to George Washington, who arrived in Boston for his first official visit as President along the Post Road.
