Did you know??? Route 14 in Connecticut and Rhode Island used to be part of the Revolutionary Road back in the late 18th century.
In the 1930s, Route 14 used to go from one end of the state to the next, even before crossing into Rhode Island en route to Downtown Providence. It incorporated roads in Middletown, Waterbury, and Middlebury that we now know as Route 64, Route 322, and Route 66. In Plainfield, Route 14 is split into two branches, one of which was once known as Route 14A (see outline I created on Google Maps).
The Route 14 of today is truncated to the corner of Brick Top Road and Boston Post Road (today’s route 66, formerly U.S. 6A) in Windham.
