Amends the powers of the Turnpike Authority (Authority) as found in GS 136-89.183, removing the cap on the number of projects the Authority can study, plan, develop and undertake preliminary design work on (previously, Authority was limited to only nine projects at one time). Allows the Authority to design, establish, purchase, construct, operate and maintain no more than 11 projects (previously, could only do so for the projects specified in the statute), with the previously specified projects included in the 11 projects. Provides that the segments of the Triangle Expressway known as NC 540, Triangle Parkway, and the Western Wake Freeway are considered to be one project (previously, was considered as three separate projects).
