Welcome to Connecticut Roads.
This is the place for information on every numbered highway -- living, extinct, or proposed -- in Connecticut. I have history for all of them, and custom maps and more details for some. If you're short on time, just type the route number in the box and press Find:
Links to all parts of this site are on the right. Below are some highlights and ideas of where to start. Also see updates to this section of the site.
I also have a retrospective of Connecticut's official highway maps.
State routes are numbered between 2 and 999; however, those above 399 are "Secret" routes, maintained by the state but not signposted. Connecticut does not allow a state route with the same number as a US or Interstate route.
Connecticut started numbering its highways around 1922, predating the US route system's inauguration in 1926. The route numbers in the 1920s were almost completely different from those today.
In response to changing laws for federal highway aid, the state in 1932 renumbered most of its highways, creating many routes (such as 67, 58, and 87) you would recognize today. Throughout the 1930s, 40s and 50s there were scattered changes. Along with the signed routes was a system of unposted "secret" routes, with administrative numbers reaching the 900s (and beyond).
In 1961 the state decided to re-examine its highway system, and reclassified hundreds of miles of roads. Some state routes were deleted (turned over to the town), some created, and many renumbered. Most signed routes above 220 are a product of this reclassification. The state's secret routes were renumbered into a geographically grouped system; for example, routes in Eastern Connecticut were numbered in the 600s.
Recent highway projects completed in Connecticut include:
The days of new freeways are over; we won't see any of the ambitious 1960s plans revived any time soon. A few projects remain on the books:
