Interstate 840 (I-840) is an Interstate Highway in the U.S. state of North Carolina. It is currently in two sections traversing 5.77 miles (9.29 km) total in Guilford County; when completed, it will form the northern section of the Greensboro Urban Loop.
I-840 currently exists in two segments that will eventually form the northern bypass around Greensboro.
The western segment, a divided six-lane urban freeway, begins at the interchange of I-40/I-73/US 421 and goes north for 3.56 miles (5.73 km) to Bryan Boulevard, where it terminates. Currently, this segment is signed as "Future" because it does not reconnect to another U.S. Route or Interstate; however, it has been a federally recognized interstate since 2011 despite the current banner. The entire route is in concurrency with I-73.
The eastern segment, a divided four-lane rural freeway, begins at US 70 (Burlington Road) and goes south for 2.21 miles (3.56 km) to the I-40/I-85/I-85 Bus interchange, its eastern terminus. The entire route is in concurrency with I-785. The eastern segment is currently unsigned with plans of it remaining as a hidden designation for I-840 until it connects with the western segment.
