Interstate 785 (I-785) is an Interstate Highway in the U.S. state of North Carolina. Currently traversing 7 miles (11 km) in eastern Guilford County, in concurrency with I-840; when completed, it will connect Greensboro to Danville, Virginia.

Route description[edit]

I-785 begins at the interchange of I-40/I-85/I-85 Business. Heading north, it connects with U.S. Route 70 (US 70) before ending at its current northern terminus at US 29. The entire route is in a hidden concurrency with I-840.

Future corridor signs of I-785 are marked along US 29 between Greensboro and Danville. In Virginia, SR 785 is the unsigned interim route number until I-785 is built to interstate standards.


The designation was approved in 1997 at the request of a coalition of counties in North Carolina and Virginia who saw it as a way of further developing that area's economy. Most of the route will use existing US 29 north of Greensboro; however, for a few miles I-785 will run between US 29 and its parent route, I-85 on the Greensboro Urban Loop, which will also carry the I-840 designation. Construction of this highway was due to begin in 2011. With the upgrade of the Danville Expressway to a four-lane route in 2004, the I-785 route in Virginia is complete (and has been given the interim designation SR 785), but US 29 still needs to be upgraded to Interstate standards in North Carolina between the Greensboro Loop and Reidsville before the route can be signed as an Interstate. Currently, there are no projects scheduled by the North Carolina Department of Transportation to do so. Given that in the spring of 2006 NCDOT put up mileposts and added numbers to exit signs from Reidsville to the Virginia border reflecting US 29's mileage, an upgrade of this highway to an interstate does not seem to be in their immediate plans.[3][4]

On July 31, 2013, NCDOT got approval from the Federal Highway Administration (FHWA) to co-sign the first section of I-785 with I-840 in eastern Guilford County officially establishing I-785 in North Carolina.[5]


In Greensboro, 5.5 miles (8.9 km) of the eastern loop of the Greensboro Urban Loop from US 70 to US 29, with an interchange at Huffine Mill Road, is complete.[6] This section was planned to be a concurrency of I-840 and I-785, though when it opened on December 6, 2017, it was signed as I-785.[7] [8] The estimated cost of the project was $119 million.[9][10]

After the Greensboro Urban Loop is completed, NCDOT and Greensboro DOT plan to add an interchange for Cone Boulevard (SR 2565). Plans for the interchange have existed since 2004; however, no time table or funding is available at this time.[11] Nor is there funding available to upgrade US 29 north of I-785 to US 158 in Reidsville to interstate standards, necessary for I-785 to be signed northward to Virginia. Roadway improvement and interchange upgrades to Summit Avenue (SR 2526)/Reedy Fork Parkway (SR 2790) is planned to begin in 2020 with a scheduled completion in 2023, known as STIP Number R-4707, with an estimated cost of $44.1 million[12]. NCDOT is currently upgrading exit signage for the current US 29 freeway north of Reidsville, but adding US 29 milepost exit numbers to the signs, indicating this section's designation as I-785 is years away.[13]
