Routes are generally state-maintained. There is also a system of unsigned state highways known as State Roads (SR) and Special Service Roads (SSR).

The Connecticut Department of Transportation (ConnDOT) maintains a system of state highways to serve the predominant flow of traffic between towns within Connecticut, and to towns in surrounding states. State highways also include roads that provide access to federal and state facilities (Special Service Roads).

The state highway system consists of roads indicated on the official ConnDOT map and highway log. As of January 1, 2007, the state highway system contains a total of 3,719 miles (5,985 km) of roads (not including ramps and interchange connections), corresponding to approximately 20% of all roads in the state. All state highways are state-maintained except for several segments (totaling 4 miles) that are locally maintained. All interstate highways and U.S. highways in the state are part of the state highway system.

All state highways are given a number designation. Most state highways are assigned Route numbers (including U.S. highways and interstates). Route numbers are in the 1-399 range, with the exception of Interstates 684 and 691. State highways that are special service roads are assigned SSR numbers and are unsigned. SSR numbers are in the 400-499 range. Another set of unsigned state highways are called State Roads and are given SR numbers. These state roads are either feeder roads that interconnect state highways together, or long entry/exit ramps to freeways (often called connector roads). SR numbers are in the 500-999 range. Signposted state highways that are not U.S. highways or interstates are signed with the square Connecticut state highway shield.

Routes are signed state highways and are assigned numbers from 1 to 399 (with the exception of I-684 and I-691). All state, U.S. and Interstate highways are part of the same numbering system. In 1926, the U.S. highway system was implemented. U.S. Routes 1, 5, 6, and 7 were used as designations on several primary state highways, replacing New England routes 1, 2, 3, and 4, respectively. The other New England routes that were not re-designated as U.S. routes became ordinary state highways but kept their number designation, which are used even today (with some realignment). In 1958, Connecticut received approval for the route numbers of its three primary Interstate highways: I-84, I-91, and I-95. State highways with the same number designation as the Interstate highways were renumbered to avoid duplication of route numbers.
