Interstate 785 North Carolina/Virginia

The southernmost segment of Interstate 785 consists of an overlap with Interstate 840 along the eastern flank of the planned Greensboro Beltway. NCDOT applied for the designation of I-785 along this stretch in fall of 1997. It was approved by FHWA on July 31, 2013 and by AASHTO on October 21, 2013. The overlap represents only the second occurrence of two three-digit Interstates combined on a single stretch of freeway within the Interstate system. The first instance is where Interstate 271 and Interstate 480 overlap near Cleveland.

Extension of the Greensboro Urban Loop north from U.S. 70 to U.S. 29 is underway with right of way acquistion started in 2012 and construction breaking ground in 2014. Details on the project can be found at NCDOT: Greensboro Urban Loop.

Proposed Routing

A planned spur of Interstate 40 and Interstate 85 from Greensboro, North Carolina, northward along the Greensboro Loop (Interstate 840 and U.S. 29 freeway/High Priority Corridor 17 north to Danville, Virginia. Interstate 785 appeared in North Carolina's Strategic Highway Corridors map as of November 12, 2004.

The freeway was jointly agreed upon by North Carolina and Virginia officials April of 1997 after the advocation from the Interstate Connection: Alliance for Economic Growth in the fall of 1996. The organization was comprised of business and government leaders who touted the route for potential economic improvements to the area including diversifying the economy, creating new jobs, generating additional tax revenue and enhancing regional cooperation.1

North of U.S. 70 in east Greensboro, the route designation exists solely on paper with the exception of a few future Interstate 785 corridor guide signs posted along U.S. 29. This is due to the fact that the freeway of U.S. 29 is below Interstate standards. U.S. 29 requires modern shoulders, acceleration and deceleration ramps, and other improvements to qualify for Interstate standards.

High Priority Corridor

Interstate 785 in its entirety is part of High Priority Corridor 17 and 40: Route 29 Corridor.


The establishment of Interstate 785 from Interstate 85 in Greensboro, North Carolina, north to the U.S. 29 and U.S. 58 interchange in Danville, Virginia, via the U.S. 29 freeway was approved by AASHTO on November 14, 1997.


Improvements to U.S. 29 between Greensboro and the North Carolina-Virginia state line are already underway. Construction in Danville brought that section of U.S. 29/Future Interstate 785 up to Interstate standards.
