In the U.S. state of North Carolina, Interstate 40 Business (commonly known as Business 40) is an 18.5-mile-long (29.8 km) business loop of Interstate 40; which serves the cities of Winston-Salem and Kernersville.
Business 40 begins at exit 188 of Interstate 40 and exit 238 of US 421 in Winston-Salem. Traveling east, the route goes through the downtown of Winston-Salem, which has several quick on/off exits. It then continues south of Kernersville, before meeting back with Interstate 40 (exit 206) near Colfax. The entire route is 4-lane at freeway grade, it is also completely overlapped with US 421.
Originally known as the Downtown Expressway, it was one of the state's first urban freeways, predating the Interstate Highway System. The first section of the expressway was opened on January 6th, 1958, and ran from Cloverdale Avenue to Main Street signed as US 158. In 1959, Interstate 40 signs were added. In 1960, it was extended east to Reidsville Road. By 1962, the freeway extended west to the current junction with US 421 and east into Guilford County; it was also at that time when US 421 was rerouted from Reynolda Road to its current routing.
