#35 at Boston Post Road and Dean Park
The Upper Boston Post Road was first known as the Pequot Path and used by Native Americans. As Europeans arrived and ventured inland the trail widened to allow for horses and cattle. The first concentrated effort to broaden the trail happened in 1673. Eventually the surface was leveled to accommodate horse-drawn wagons and stagecoaches.
Between Boston and Springfield, Massachusetts, along the Upper Boston Post Road, there are 40 surviving milestones. In 1971, they were added to the National Register of Historic Places.

The Franklin Myth
It is said that the milestones were erected in 1753 by Benjamin Franklin when he was serving as Deputy Postmaster General. He attached a homemade odometer to a wagon wheel to measure the miles of the Post Road. Marking each mile with a stake, workers following behind him erected stone markers to indicate the distance from Boston.
In 1971, a detailed study of the Franklin papers at Yale University failed to reveal any references to the roadside milestones.
In 2016, milestone #43 was moved from the West Main Street on-ramp of Route 290 East to the Shrewsbury Town Common to protect the marker and give it a home where all could appreciate it.
