context_page_description: The Connecticut Department of Transportation 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.
  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 of roads, corresponding to approximately 20% of all roads in the state. All state highways are state-maintained except for several segments 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. 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.
context_section_description: 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.
