Interstate 495 A portion of I-87, originally designated I-495, was first designated as an Interstate Highway on February 20, 2013, when the
North Carolina Department of Transportation (NCDOT) submitted a request to the
American Association of State Highway and Transportation Officials (AASHTO) in order to establish I-495 as a new
auxiliary route of
I-95. The proposed route would begin at
I-440/
US 64/
US 64 Bus. in
Raleigh and would end at
I-95, in
Rocky Mount, completely concurrent with US 64. On March 15, 2013, AASHTO received a modified request from NCDOT requesting the establishment of I-495 from I-440 to I-540 () and Future I-495 from I-540 to I-95 (). It was approved, though needed an additional approval from the
Federal Highway Administration (FHWA). The freeway section, the part that was originally to be signed I-495 and continuing east to US 64 Bus., was completed in 2006. From I-440 to Rolesville Road, the freeway was built to
Interstate standards, which is why the first official section of I-495 was able to connect between I-440 and I-540. East of Rolesville Road, the freeway was built in sections, since 1975. This older section of freeway will eventually be expanded to Interstate standards, which include road rehabilitation and wider lanes and shoulders.
Renumbering in
Raleigh Long-term plans by the Raleigh–Durham area's Regional Transportation Alliance (RTA) called for extension of the Interstate east of I-95 toward
Elizabeth City, then northeastward to the
I-64/
I-464 interchange in
Hampton Roads. NCDOT proposed the
Interstate 44 designation for the Raleigh–Norfolk High Priority Corridor consisting of portions of the I-495 and US 64 in North Carolina and
US 17 in North Carolina and Virginia. The route would connect two of the largest US metropolitan areas lacking an Interstate connection: the
Research Triangle area around Raleigh and the Hampton Roads area around Norfolk. Representative
G. K. Butterfield introduced legislation in June 2014 to add the corridor to the Interstate Highway System through Congressional authority. An NCDOT policy paper said they were "seeking language in the reauthorization of surface transportation programs legislation to enhance the description of the Raleigh–Norfolk Corridor to include the route via
Rocky Mount–
Elizabeth City for clarity, and to designate the entire route from Raleigh to Norfolk as a future part of the Interstate system as I-44 or I-50". Had the I-44 designation been approved, it would have been discontinuous with the current
I-44, which runs between
Wichita Falls, Texas, and
St. Louis, Missouri. The proposed corridor was officially designated as a future Interstate with the passage of the
Fixing America's Surface Transportation Act (FAST Act) on December 14, 2015. Soon, several other route numbers were discussed and the RTA set their preference on two more-likely candidates: I-56 if an east–west designation were chosen or I-89 if a north–south designation were chosen. I-56 is not in use, while
I-89 exists in
Vermont and
New Hampshire, far north of this corridor. On May 25, 2016, AASHTO instead approved I-87 as the number for the highway. The new I-87 would be noncontiguous with the
route with the same number in
New York. The I-87 designation pays tribute to several important dates in the history of both North Carolina and Virginia: the
Roanoke Colony was founded in 1587,
James Madison's
Virginia Plan helped to develop the
US Constitution in 1787, and
North Carolina State University was created in 1887. On May 23, 2017, AASHTO approved the request by NCDOT to decommission existing I-495 and Future I-495; they were replaced by I-87 and Future I-87. I-87 signage were installed on September 5, 2017; in May 2019 milemarkers and exit numbers were changed along the already completed segment from the I-440 junction to Rolesville Road. Exit numbers and mileage along the portion coincident with I-440 will retain I-440 mileage and exit numbers. I-87 will continue east along US 64 to I-95 after the road is expanded to Interstate standards. ==Future==
