It is currently in two sections traversing {{convert|14.17|mi|km}} total in Guilford County; when completed, it will form the northern section of the Greensboro Urban Loop. Route descriptionI-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 {{convert|7.36|mi|km}} to US 220 (Battleground Avenue), where it terminates. The route is in concurrency with I-73 south of Bryan Boulevard. The eastern segment, a divided four-lane rural freeway, begins at US 29 (Ohenry Boulevard) and goes south for {{convert|6.81|mi|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. Both sections have a maximum speed limit of {{convert|65|mph}}. History{{see also|Greensboro Urban Loop}}I-840 first appeared in the early 2000s as a proposed routing for the northern half of the Greensboro Urban Loop. In 2002, the first segment opened between US 70 and I-40/I-85; however, it was unsigned and designated as SR 3269; by 2006, Future I-840 signage was added at the US 70 interchange. In December 2007, a second segment opened along its routing between I-40/US 421 and Bryan Boulevard and was signed as Future I-73/I-840. In 2010, NCDOT submitted its official request, to both the AASHTO and the FHWA, to designate the two existing segments of the northern half of the Greensboro Urban Loop as I-840 and the {{convert|15.26|mi|km|adj=on}} unbuilt portion as Future I-840. AASHTO approved the request on October 29, 2010 followed by FHWA on August 2, 2011.[4] On September 2, 2011, NCDOT certified the route change establishing I-840.[5] Construction on the northern half of the Greensboro Urban Loop resumed in 2013 with the six-lane, {{convert|3.8|mi|km|adj=on}} segment between Bryan Boulevard and Battleground Avenue (US 220), which will be signed as I-840.[6] At a cost of $123 million, it was expected to be completed in early 2018.[7][8][9] This section opened on April 19, 2018, four days ahead of schedule.[10] In late 2014, a {{convert|5.5|mi|km|adj=on}} segment, between US 29 and US 70, also began construction; however, it was signed as I-785 with I-840 as a hidden designation until the completion of the Loop.[11] This section opened in December 2017.[12][13] Future{{As of|2018|April}}, there are two segments of the northern half of the Greensboro Urban Loop to be completed.
Segments along the western loop will be designated as I-840 upon opening; segments along the eastern loop will have a hidden I-840 designation until it joins with the western loop, fully designating the entire northern half of the Greensboro Urban Loop. Long term plans call for two additional interchanges along I-840: Fleming–Lewiston Road (SR 2136) and Cone Boulevard (SR 2565). Plans for both interchanges have existed since 2004; however, because both are to be constructed after the I-840's completion, there is no current time table or funding for these two projects at this time.[14][19][20] {{Clear}}Exit list{{jcttop|exit|state=NC|county=Guilford|location=Greensboro|length_ref=[1][2]}}{{NCint|exit|mile=0.0 |mspan=3 |exit=— |road={{Jct|state=NC|I|73|US|421|I|85|dir1=south|dir2=south|to3=to|city1=Asheboro|city2=Durham|city3=Raleigh}} |notes=Continuation as I-73 and US 421 }}{{NCint|exit |type=concur |mile=none |exit=103A |road={{jct|state=NC|I|40|dir1=east|city1=Greensboro}} |notes=Northern end of US 421 concurrency; northbound exit left |nspan=2 }}{{NCint|exit |type=concur |mile=none |exit=103B |road={{jct|state=NC|I|40|US|421|dir1=west|dir2=north|city1=Winston-Salem}} |notes=none }}{{NCint|exit |mile=1.6 |exit=104 |road=West Friendly Avenue }}{{NCint|exit |mile=3.6 |mspan=2 |exit=3A |road=Bryan Boulevard – Downtown |notes=I-73 exit 107A }}{{NCint|exit |type=concur |mile=none |exit=3B |road={{jct|state=NC|I|73|dir1=north|location1=PTI-GSO Airport|location2=Martinsville}} |notes=I-73 exit 107B; northern end of I-73 concurrency }}{{NCint|exit |type=unbuilt |road=Fleming–Lewiston Road |notes=Future interchange (unfunded)[19] }}{{NCint|exit |exit=6 |road={{jct|state=NC|US|220|name1=Battleground Avenue}} }}{{NCint|exit |type=unbuilt |exit=8 |road=Lawndale Drive |notes=Future interchange (under construction)[6][16] }}{{NCint|exit |type=unbuilt |exit=10 |road=North Elm Street |nspan=2 |notes=Future interchanges (funded)[18] }}{{NCint|exit |type=unbuilt |exit=11 |road=Yanceyville Street |notes=none }}{{NCint|exit |type=concur |mile= |exit=14 |road={{Jct|state=NC|I|785|US|29|dir1=end|city1=Greensboro|location2=Danville}} |notes=Northern end of I-785 concurrency }}{{NCint|exit |type=unbuilt |exit=16 |road=Cone Boulevard |notes=Future interchange (unfunded)[11][20] }}{{NCint|exit |mile= |exit=17 |road=Huffine Mill Road }}{{NCint|exit |mile=18.6 |exit=18 |road={{Jct|state=NC|US|70|name2=Burlington Road|road=To Wendover Avenue}} |notes=none }}{{NCint|exit |type=concur |mile=20.8 |mspan=2 |exit=21 |road={{Jct|state=NC|I|40|I|85|I|785|dir2=north|dir3=end|city1=Greensboro|city2=Durham|city3=Raleigh}} |notes=Southern end of I-785 concurrency[11] }}{{NCint|exit |mile=none |exit=— |road={{Jct|state=NC|I|85|dir1=south|city1=High Point|city2=Charlotte}} |notes=Continuation as I-85 }}{{Jctbtm|exit|keys=concur,incomplete,unbuilt}} See also
