In 1930 and '31, State Highway 202 was the numbering for present-day Route 72 between US 6 in Plymouth and Route 4 in Harwinton.

In 1932, this road became part of the old Route 117. A new Route 202 was assigned to what is now Route 101 between present-day Route 169 and the Rhode Island state line.

In 1935, Route 101 (which predated US 44 and ran along its path) was moved southward to its current routing and 202 was retired as a state route.

Though the number didn't last long as a state route, either time, it has since enjoyed long life as US 202, which was commissioned in 1935.
