List of special service roads in Connecticut

In the U.S. state of Connecticut, state highways are grouped into signed routes, unsigned special service roads (SSR), and unsigned state roads (SR). Special service roads are roads that connect a federal or state facility (including state parks and some Interstate Highway interchanges) to a signed state route.
