Route descriptionEdit

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 7.36 miles (11.84 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 6.81 miles (10.96 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 65 miles per hour (105 km/h).

HistoryEdit

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 15.26-mile (24.56 km) 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, 3.8-mile (6.1 km) 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 5.5-mile (8.9 km) 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]

FutureEdit

As of April 2018, there are two segments of the northern half of the Greensboro Urban Loop to be completed.

  • Western Loop (between US 220 and Lawndale Drive)—this 1.7-mile (2.7 km) six-lane segment is fully funded, at a cost of $54 million. Construction started in October 2016 and is expected to be completed by the end of 2020.[7][14][15]
  • Eastern Loop (between Lawndale Drive and US 29)—this 6.0-mile (9.7 km) six-lane segment is fully funded with the project to be let in February 2018. At a cost of $162 million, it will have interchanges at Yanceyville Street and North Elm Street.[7][16][17]

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.[7][18][19]
