Bypass Route

United States

In a few cases, both a bypass and a business route exist, each with auxiliary signs (e.g. U.S. Route 60 in Lexington, Kentucky). Bypass routes are less common than business routes. Many of those that existed before the era of Interstate Highways have lost their old designations. For example, in Missouri, the old bypass route of U.S. Route 71 to the east of Kansas City, Missouri was decommissioned as Interstate 435 supplanted it; the remainder that existed as suburban surface route became Missouri Route 291. Around St. Louis, Missouri, what had been U.S. Route 50 Bypass was absorbed into a diversion of U.S. Route 50 from Interstate 44 and Interstate 64.
