Interstate [[Business route|business routes]] are roads connecting a central or commercial district of a city or town with an [[Interstate highway|Interstate]] bypass. These roads typically follow along local streets often along a former [[United States Numbered Highways|U.S. Route]] or [[state highway]] that had been replaced by an Interstate. Interstate business route [[reassurance markers]] are signed as either [[Loop route|loops]] or [[Spur route|spurs]] using a green [[Highway shield|shield]] shaped sign and numbered like the shield of the parent Interstate highway.

Along [[Interstate 35]] (I-35), business routes are found in four states through which I-35 passes: [[Texas]], [[Missouri]], [[Iowa]], and [[Minnesota]]. Some states regard Interstate business routes as fully integrated within their state highway system while other states consider them to be either local roads to be maintained by county or municipal authorities or a hybrid of state and local control. Every state along I-35 regards its business routes as fully incorporated members of their respective state maintained highway systems.

Although the public may differentiate between different business routes by the number of the parent route and the location of the route, there is no uniform naming convention. Each state highway department internally uses its own designations to identify segments within its jurisdiction.
