Business routes of Interstate 40

Interstate business routes are roads connecting a central or commercial district of a city or town with an Interstate bypass. These roads typically follow along local streets often along a former U.S. route or state highway that had been replaced by an Interstate. Interstate business route reassurance markers are signed as either loops or spurs using a green shield shaped and numbered like the shield of the parent Interstate highway. From central Oklahoma westward, the business routes often follow the historic alignment of the former U.S. Route 66 (US 66).
