Route description

History

The southern part of Route 31 was commissioned as part of the original alignment of US 6 in 1926. In approximately 1938, US 6 was rerouted and the old route was designated US 6A.

In 1942, US 6 was rerouted again and the old US 6A was commissioned as Route 31. In 1963, Route 31 was extended northward to its current route.^[2]
