AARoads Interstate Guide - I-885
This future interstate will run from US 64 (Future I-87) at Zebulon east to Greenville along an upgraded US 264. This proposal was announced by NCDOT on Sept. 7, 2016g with the agency sending applications for the proposal to be approved by AASHTO at their October 2016 meeting in Boston and to the FHWA. AASHTO's Committee on US Route Numbering rejected the application on 10/26/16, however, the Special Committee on Highways, of which the US Route Numbering committee is part, apparently overruled them and approved the designation at their meeting in Boston on 11/13/16.h The FHWA sent a letter approving the route as an addition to the interstate system on 11/21/16.i It is unknown at this time when any part of the route will be signed. Officials from the Greenville area lobbied state and federal agencies for the city, the largest in NC without an interstate connection, for a spur route once the I-87 designation was approved. The NCDOT 2020-2029 STIP released in August 2019 has 2 funded projects related to upgrading US 264 to Interstate Standards that started in 2019. Project I-6032 will widen the shoulders as part of a pavement rehabilitation contract in Greene County while Project I-6035 will do the same in Pitt County, the latter started on September 30, 2019. Both are east of Wilson County where US 264 is already Interstate standard There are no other upgrade projects west of Wilson County listed in the STIP document.j

PTI
Airport ConnectorPossible number for proposed freeway that would run from I-73/Bryan
Blvd near PTI Airport to split of I-40 and Business 40 west of
Greensboro, or for an alternate proposal (the I-73/74 Connector) that
would run the highway from Bryan Blvd. at NC 68 to the I-74
Winston-Salem Beltway (if both parts are built the part running from the
I-73/74 Connector south to I-40, (called the 'I-40 Connector' in some
proposals) could get another number). The I-73/74 Connector
proposal was added to the NCDOT State Transportation Improvement Program
(STIP) in November 2005 for environmental and planning purposes only. It
was then under study by the North Carolina Turnpike Authority for a
short period as to whether it could be built as a toll road. Apparently
this proved unfeasible, and is no longer listed as a NCTA proposal. The
proposed highways can be seen in this map courtesy of the Winston-Salem

Interstate 193 - Braintree to Cape CodYes, this is not a North Carolina route, but one from my home state of Massachusetts. The proposed designation for current MA 3 between I-93 in Braintree and US 6 at the Sagamore Bridge in Bourne. If one can take an interstate spur from Providence, RI to Cape Cod why can't drivers from Boston to the Cape? Besides, doesn't America's Hometown (Plymouth) deserve its own interstate?
