Interstate 840 North Carolina - Greensboro Loop

Proposed Routing

Interstate 840 in North Carolina is another in the series of proposed beltways planned for the Tarheel State. Located in the vicinity of the Triad, a rapidly growing region in the north-central portion of Norther Carolina, Interstate 840 is ultimately planned to be the Greensboro Loop around the city from Interstate 40 west of downtown Greensboro near the Piedmont Triad International Airport to Interstate 40-85 east of Greensboro. Interstate 840 represents the northern half of the Greensboro Loop; the southern half, already complete, carries Interstate 73 (western half) and Interstate 85 (eastern half).

Route Status

As of February 21, 2008, all of the southern half of the Greensboro beltway is open to traffic. Work on the northern half of the beltway commences in 2011 with the building of freeway between U.S. 70 and U.S. 29 (Future Interstate 785) east of the city. This segment of roadway will also carry Interstate 785 between Interstate 85 and the U.S. 29 corridor. The interchange at the north end will include high speed ramps to coincide with an eventual freeway upgrade of U.S. 29. Futher construction of the northern arc between Joseph Bryan Boulevard and U.S. 29 remains unfunded as of late 2008.


Construction began on the stretch of Interstate 840, between Interstate 40 west of Greensboro to Joseph Bryan Boulevard, the week of September 8, 2003. The $101.6 million project was expected to open to traffic by Summer of 2007, but did not open until February 21, 2008. This leg of the Greensboro Urban Loop was prioritized by state officials because of the benefits to area congested in proximity to the Piedmont Triad International Airport.1

The first section of Interstate 840 completed is the two-mile segment from the Interstate 40 & 85 merge to U.S. 70 east of the city. Opened in 2002, the freeway carries Future Interstate 840 shields. Future Interstate 840 also applies to the shared alignment with Future Interstate 73 from Interstate 40 to Bryan Boulevard as well.

At the time this photo was taken, Interstate 840 was not signed on northbound Interstate 85, which became apart of the new Greensboro loop route on February 21, 2004. For now, northbound Interstate 85 approaches Exit 131, Junction Interstate 40 west, Business Loop I-85 south, and Interstate 840 north to U.S. 70. Only the section from Interstate 40-85 to U.S. 70 was open at the time this picture was taken. Photo taken by Carter Buchanan (08/08/04).
