Interstate 140 is signed along the western half of the US 17 Wilmington Bypass, a planned 27-mile freeway from US 17 near Scotts Hill westward over I-40 then further west to US 74-76 then south to US 17 near the town of Town Creek. The following map shows the completed sections of the route*:

Three different construction projects were undertaken to build nearly 12 miles of the Bypass route currently open from Scotts Hill to US 421. Work began on two projects covering the 6.5 mile I-140 section from I-40 to US 421 in mid-2001. The three-mile section from I-40 to Castle Hayne Road (NC 133) was completed first, with the roadway opened to traffic on August 22, 2005.(1) The 3.5 mile section from NC 133 to US 421, including a bridge over the Cape Fear River (named for former Wilmington Mayor Dan Cameron) was opened to traffic on June 30, 2006.(2) Construction on the 5 mile section east of I-40, signed only as US 17 and known as the John J. Burney Jr. Freeway, was started in late 2003 and this section was also opened to traffic on June 30, 2006. (2,3) Interchanges along the I-140 section are for I-40, NC 133 and US 421. When the road opened these interchanges did not have exit numbers, these were added in spring or summer of 2007.(An exit list is below.) A future I-140 interchange is planned for Blue Clay Road (not to be built until after 2023(4)) which will take traffic to the Wilmington International Airport and another is to be built on the section east of I-40 for the planned Military Cutoff Extension, US 17 will actually leave the bypass and travel north on the extension to current US 17 north of Scotts Hill.(5)
Work on the next section from US 421 to US 74-76, approximately 7 miles, was originally scheduled to start in 2009, (6) but this segment's construction was delayed until 2013. Instead what was to be the final section, approximately 5 miles from US 74-76 to US 17 near its intersection with NC 87, was funded through federal stimulus moneys and work began under a design-build contract in late March 2010 (for more detail, see below).(7) As of the end of August 2012 this project was 67.3% complete.(8) Even though the route will not be a complete bypass for US 17 until after 2015, (9) when the segment to US 421 was opened, US 17 was routed over the Bypass and then south on US 421 to its existing alignment for the time being. The former US 17 through Wilmington became US 17 Business. Truck US 17, signed along streets in downtown Wilmington, was decommissioned.(5) The FHWA granted the interstate designation for the entire Wilmington Bypass route on May 31, 2003 including the section east of I-40, it is unknown at this time why NCDOT decided not to sign that portion as an interstate.(10) A proposed Wilmington end-point for I-74 (and a possible spur of I-74, see More about I-74 Here) would meet I-140 where it would intersect the existing US 74-76 freeway.(11)

The NCDOT Strategic Highway Corridor map of the Wilmington area shows I-140 being extended 9.5 miles over the proposed Cape Fear Skyway south and east back over the Cape Fear River to US 421. (See map below (13)). This is NCTA's preferred route for the Skyway, one of several proposed projects of the North Carolina Turnpike Authority (NCTA) and would be constructed as a toll highway. The preferred route of the Skyway bridge would run from Carolina Beach Road at Independence Boulevard south of Wilmington over the Cape Fear River. It would then connect to US 17 through an 8-mile-long extension of Interstate 140 from it's current planned end near Town Creek. This alignment has not been finalized (see below), however, and other routes do not have the toll highway meeting I-140. The project, if officially approved, is expected to cost between $1 and 1.5 billion and would take five years to build, the earliest construction would start is 2013.(14) A feasibility study completed during the summer of 2008 indicated only about 50% of the construction could be funded by tolls. Additional funding from the state would be needed.(15) More information is available at the official NC Turnpike Authority Cape Fear Skyway Page.
NCDOT announced in July 2009 that federal stimulus funds would help start further construction on I-140/US 17. The next section to be constructed though was not going to be from US 421 to US 74/76, Segment "B", but the section between US 74/76 and US 17 near NC 87, Segment "A''. This is a design/build construction project which began in March 2010. The project is planned to be completed by mid-2013. This segment was more 'shovel ready' and able to receive stimulus funds. Segment "B" has another water crossing and was still undergoing right-of-way purchasing. The schedule under the new Loop Prioritization program announced in the Fall of 2011 was that work on the US 421 to US 74/76 section would start in 2013 which means though there will be a gap in the route for at least a couple years. (16) The entire route could open as early as 2015.
This is not the first route NCDOT proposed as I-140. In 1999, officials in Sanford wanted the newly completed US 1 freeway from Raleigh to their city designated an interstate to help attract further business. NCDOT applied to the FHWA to have the freeway designated as Interstate 140. The FHWA rejected the designation, however, saying Sanford was not a large enough urban area to warrant its own interstate highway. Perhaps some day if all of US 1 is made a freeway between I-40 in Raleigh and I-73/74 in Rockingham (as proposed in the NCDOT Strategic Highway Corridors plan) then someone may suggest revisiting a US 1 interstate designation proposal.
