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. Roads classified by the Connecticut Department of Transportation as special service roads are given an unsigned number designation between 400 and 499, or 1001.
