List of gaps in Interstate Highways: There are gaps in the Interstate Highway system, where the roadway carrying an Interstate shield does not conform to the standards set by the Federal Highway Administration (FHWA), the body that sets the regulations for the Interstate Highway System.  For the most part, the Interstate Highway System in the United States is a connected system, with most freeways completed; however, some Interstates still have gaps.  These gaps can be due to unconnected segments of the same route or from failure of the road to fully conform to Interstate standards by including such things as at-grade crossings, traffic lights, undivided or narrow freeways, or movable bridges (lift bridges and drawbridges).  This article deals with present-day gaps, as such examples were far more numerous during construction of the Interstate Highway System and the upgrading of existing roads to meet these standards, which did not occur everywhere at the same time.  Temporary gaps, such as lane closures that reduce traffic to one lane and reduce speed limits, are also excluded.

Interstate Highway System: The Dwight D. Eisenhower National System of Interstate and Defense Highways (commonly known as the Interstate Highway System, Interstate Freeways, or simply the Interstate) is a network of controlled-access highways that forms a part of the National Highway System of the United States.  The system is named for President Dwight D. Eisenhower, who championed its formation.  Construction was authorized by the Federal Aid Highway Act of 1956, and the original portion was completed 35 years later, although some urban routes were cancelled and never built.  The network has since been extended and, as of 2013 , it had a total length of 47856 mi .  s of 2013 , about one-quarter of all vehicle miles driven in the country use the Interstate system.  In 2006, the cost of construction was estimated at about $425 billion (equivalent to $ in 2016 ).
