'''Route&nbsp;31''' is a north&ndash;south state highway in Connecticut running for {{convert|14.34|mi|km}} from Route&nbsp;74 in Vernon to Route&nbsp;32 in Mansfield. Although it is officially logged as an east-west route, it is signed north-south.

==Route description==

Route&nbsp;31 begins at an intersection with Route&nbsp;74 in Vernon and heads southeast, intersecting Route&nbsp;30, and I-84 at exit 77 before crossing into Tolland.<ref name=ctlog/>

In Tolland, Route&nbsp;31 continues southeast before turning south briefly before crossing into Coventry. In Coventry, Route&nbsp;31 continues south to a concurrency with US&nbsp;44. The two highways run together for slightly more than one mile (1.6&nbsp;km) before Route&nbsp;31 heads southeast, crossing Route&nbsp;275 before continuing into Mansfield.

In Mansfield, Route&nbsp;31 continues southeast before ending at an intersection with Route&nbsp;32.

==History==

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

In 1942, US&nbsp;6 was rerouted again and the old US&nbsp;6A was commissioned as Route&nbsp;31. In 1963, Route&nbsp;31 was extended northward to its current route.<ref>[http://www.kurumi.com/roads/ct/ct31.html Connecticut Routes, Route 31]</ref>
