The North Carolina Turnpike Authority was created in 2002 to speed the implementation of needed transportation improvements by funding some projects with tolls. Governed by a nine-member authority board, it is located within the Department of Transportation and under the direct supervision of the Secretary of Transportation. The authority has the power to study, plan, develop and undertake preliminary design work on up to eleven turnpike projects. At the conclusion of these actives, the authority is authorized to design, establish, purchase, construct, operate and maintain toll highways and bridges. The authority is also authorized to designate one or more lanes of any highway, or portion thereof, into a high-occupancy toll lanes (HOT lanes) or other type of managed lanes; provided that such designation does not reduce the number of existing non-toll general purpose lanes.
 The nine-member Authority Board consist of eight appointees, from the General Assembly (four members) and Governor (four members), and the Secretary of Transportation. The General Assembly appoints four members, two by recommendation by the President pro tempore of the Senate and two by recommendation by the Speaker of the House of Representatives. Appointments to the board are four-year staggered terms. The Chair of the Authority is selected by the Authority Board. Members of the North Carolina Board of Transportation may serve as members of the Authority Board.
 Upon end of term, all members of the Authority Board will remain in office until their successors are appointed and qualified. The original appointing authority may appoint a member to serve out the unexpired term of any member. Each member of the Authority Board serves at the pleasure of the appointing authority. The Chair of the Authority serves at the pleasure of the Authority Board. The appointed members of the Authority Board receives no salary for their services; however, are entitled to receive per diem and travel allowances.
 An executive director, appointed by the Authority Board, serves as the Authority's chief administrative officer and is responsible for the daily administration of the toll roads and bridges constructed, maintained or operated. The Executive Director or his/her designee shall appoint, employ, dismiss and, within the limits approved by the Authority Board, fix the compensation of administrative employees as the executive director deems necessary.
 The North Carolina Turnpike Authority was established on October 3, 2002, by ratification of House Bill 644 (S.L. 2002-133) and signed by Governor Mike Easley. In its original draft, the authority was independent and only able to establish the first three projects in the following conditions: one project located in whole or in part in a county with a population equal to or greater than 650,000 persons; one project located in a county or counties that each have a population of fewer that 650,000 persons; and one project shall be a bridge of more than two miles (3.2 km) in length going from the mainland to a peninsula bordering the state of Virginia. In 2005, Senate Bill 622 (S.L. 2005-276) added new language regarding establishing tollways on Federally funded highways designated as interstates; the purpose was so that the state can possibly add tolls along Interstate 95 (I-95), if approved by the Federal Highway Administration (FHWA) and all interested parties along the route. In 2006, Senate Bill 1381 (S.L. 2006-228) focused the project to the following:
 The 2006 law also made an exception, to the prohibition of converting any segment of the nontolled state highway system to a toll, by specifically identifying I-540 that was currently under construction as of July 1, 2006, located in Wake and Durham counties, and extending from I-40 southwest to North Carolina Highway 55 (NC 55). In addition, the law also mandates the North Carolina Department of Transportation (NCDOT) to maintain an existing, alternate, comparable non-toll route for each toll route constructed by the authority. In December 2006, FHWA approved the tolling project on what was going to be I-540 along the Western Wake Freeway.
 In 2008, Senate Bill 1697 (S.L. 2008-225) established the enforcement of tolls on turnpike projects and clarified and revised several sections, including: removal of I-540 from project list, collection of tolls (via mail or transponder), payment system for tolls, civil penalties for not paying tolls and procedures for contesting liability for unpaid tolls. The Triangle Parkway was also renamed the Triangle Expressway, which incorporated segments also known as NC 147 (Triangle Parkway) and NC 540 (Western Wake Freeway), in Wake and Durham counties.
 In 2009, House Bill 1617 (S.L. 2009-343) transferred the functions and funds of the North Carolina Turnpike Authority to NCDOT to conserve expenditures and improve efficiency. In August, the groundbreaking ceremony took place on the first phase of the Triangle Expressway. On May 4, 2010, the Authority signed a contract with TransCore to provide transponders.
 In December 2011, phase one of the Triangle Expressway was open to traffic; on January 3, 2012, toll collection began. On June 26, 2012, Senate Bill 895 (S.L. 2012-85) gave the authority the ability to enter into reciprocal toll enforcement agreements with other toll agencies. In August, 2012, phase two of the Triangle Expressway was open to traffic and immediately began toll collection. In December 2012, phase three of the Triangle Expressway was opened to traffic; on January 3, 2013, toll collection began on the final section.
 In 2013, House Bill 817 (S.R. 2013-183) made sweeping changes to the authority, including: removal of several turnpike projects, including the Triangle Expressway Southeast Extension, Garden Parkway, Cape Fear Skyway and the Mid-Currituck Bridge. reestablishing the turnpike project limit to nine, with the existing Triangle Expressway counting as three and the Monroe Connector/Bypass as one. New turnpike projects must follow new conditions prior to the letting of a contract for project. A limit of up to three agreements with a private entity, with an agreement of no more than 50 years from the date of the beginning of operations on the toll facility. The designation of HOT and managed lanes.
 As of 2018, the Authority operates 37.5 miles (60.4 km) of tollways in four counties in North Carolina:
 The authority currently has one set of HOT lanes in North Carolina:
 Unlike the turnpike projects, the Authority is not limited to the number of managed lane projects it may construct and operate. The authority may also convert lanes that may previously have been designated as high-occupancy vehicle lane (HOV) or other type of managed lanes; provided that such designated does not reduce the number of existing non-toll general purpose lanes. In making such designations, the authority will specify the high-occupancy requirement or other conditions for use of such lanes, which may include restricting vehicle types, access controls, or the payment of tolls for vehicles that do not meet the high-occupancy requirements or conditions for use.
 As of 2023, two additional managed lane projects were fully funded and are either scheduled or are under construction:
 As of 2018, one turnpike project is fully funded for construction:
 Any other project proposed by the authority requires prior consultation with the Joint Legislative Commission on Governmental Operations. For a project to be considered a turnpike project, it must meet the following conditions prior to the letting of a contract for the project: 1) Two of the projects must be ranked in the top 35 based on total score on the department-produced list entitled "Mobility Fund Project Scores" dated June 6, 2012, and, in addition, may be subject to G.S. 136-18(39a). 2) Of the projects not ranked as provided in (1), one may be subject to G.S. 136-18(39a). 3) The project shall be included in any applicable locally adopted comprehensive transportation plans. 4) The project shall be shown in the current State Transportation Improvement Program (STIP). 5) Toll projects must be approved by all affected Metropolitan Planning Organizations and Rural Transportation Planning Organizations for tolling.
 Stipulated in the 2013 law, proposed toll road and bridges must go through same process as other transportation projects, have an STIP score and rated with other criteria contained in the Strategic Mobility Formula. NCDOT will circulate a draft of the STIP for public comment in December 2014. NCDOT anticipates the Board of Transportation will adopt it in June 2015. Listed below are proposed projects, currently in review and subject to change:
 The NC Quick Pass is a pre-paid account used for all electronic toll collection (ETC) facilities in North Carolina. Three types of transponders are available: transponder sticker (free version), E-ZPass (hard case) transponder and E-ZPass bumper-mounted transponder. Personal (limited to five transponders/vehicles) and business accounts (unlimited) are available; a $1 fee is imposed per month if the account has been inactive for 12 months.
 While NC Quick Pass users receive a discounted toll rate, non-users will be invoiced at a higher toll rate through the bill by mail program. This is done when a vehicle passes through a toll gantry, where an overhead camera will take a video image of the license plate. The registered owner of the vehicle is identified through the Division of Motor Vehicles and a bill by mail is sent for payment.
 If the bill is not paid within 30 days from the date of the bill, it may escalate to include fees, civil penalties, DMV registration holds, submission to a collection agency, or all of the above.
 NC Quick Pass is interoperable with the following ETC systems:
 The toll collection equipment used in North Carolina, Florida, and Georgia are compatible, so that NC Quick Pass drivers may simply use any NC Quick Pass transponder in Florida and Georgia, and vice versa (SunPass and Peach Pass drivers may simply use their transponder in North Carolina).
 The North Carolina Turnpike Authority and North Carolina Department of Transportation received criticism following the introduction of a law allowing toll highways and bridges in the state in 2002. Introduced to speed along the implementation of transportation improvements, many of the projects selected by the Authority were controversial, leading to delays. Originally planned to be an extension of I-540, the Triangle Expressway garnered criticism from both politicians and residents for tolling the Western Wake Freeway and for the organisers being unable to sell bonds to fund the project.  Following its opening, criticism shifted onto its expansion with towns raising issues about its routing and environmental concerns. Other projects, such as the Garden Parkway and Monroe Connector/Bypass prompted fear of additional urban sprawl, the criticism of politicians who had land deals along the routes, and generated lawsuits stemming from the flawed environmental studies.  Both the Cape Fear Skyway and Mid-Currituck Bridge were criticized[by whom?] as expensive pork projects. In response to the criticism the North Carolina General Assembly removed the Garden Parkway, Cape Fear Skyway and Mid-Currituck Bridge from the authority's purview.
 A more recent contract between the authority and Cintra to build I-77 HOT lanes and operate them for 50 years provoked local groups to hire legal counsel and attempt to have it nullified. Additional criticisms have stemmed from the irregular distribution of toll roads recommended by the authority throughout the state.
