U.S. Route 70 in North Carolina
U.S. Route 70 (US 70) is a part of the United States Numbered Highway System that runs from Globe, Arizona, to the Crystal Coast of the US state of North Carolina. In North Carolina, it is a major 488-mile-long (785 km) east–west highway that runs from the Tennessee border to the Atlantic Ocean. From the Tennessee state line near Paint Rock to Asheville it follows the historic Dixie Highway, running concurrently with US 25. The highway connects several major cities including Asheville, High Point, Greensboro, Durham, Raleigh, Goldsboro, and New Bern. From Beaufort on east, US 70 shares part of the Outer Banks Scenic Byway, a National Scenic Byway, before ending in the community of Atlantic, located along Core Sound.

A concurrency in a road network is an instance of one physical roadway bearing two or more different route numbers. When two roadways share the same right-of-way, it is sometimes called a common section or commons. Other terminology for a concurrency includes overlap, coincidence, duplex, triplex, multiplex, dual routing or triple routing.
An extreme example: I-40, I-85 Business, US 29, US 70, US 220, and US 421 formerly ran concurrently in Greensboro, North Carolina. In 2008, I-40 was rerouted off this road but was put back on it later that same year with US 220 being rerouted instead. US 421 was also rerouted in 2009.
