Watertown's Transportation Network

Watertown is a densely populated community with approximately 31,000 people within 4.1 square miles. Watertown's transportation network has allowed the community to grow from a Colonial center of trade and farming in the 1600 and 1700s into an industrial center in the late 1800s and early to mid-twentieth century. The road system was expanded and improved to address the housing boom of the 1920s-and 1930s, as well as the more recent growth in housing after World War II.

Today, Watertown has a transportation network of approximately 80 miles of roads in what is primarily a built-out community. The network has served the community well despite the challenges of working with historic paths, which provided a basis for the current system. Watertown is now working on implementing innovative transportation improvements for better safety and more mobility of residents while considering its part in the regional network.
