Construction began on NTTA's oldest existing toll road, the Dallas North Tollway, in 1966, and its first segment (from I-35E to I-635) was opened in 1968.

The Tollway (as it is popularly known) has (along with general Dallas-area growth) expanded continually northward, opening extensions in 1987, 1994, and most recently in 2007.

TollTag is the electronic toll collection system used by the NTTA in the Dallas / Fort Worth metro area.

[11] A multi-year audit released in October 2011 stated that the NTTA had inappropriate discussions with consultants while they were in the midst of bidding on lucrative Tollway contracts, as well as not having a firmly defined code of corporate ethics.

[12] Various DFW news outlets first started reporting that the North Texas Tollway Authority (NTTA) had been raided by Federal Bureau of Investigation (FBI) officials in late October 2011.

[13] Four years after that article was published, January 13, 2015, the NTTA finally released a nine-page PDF document entitled 'NTTA RUMORS Q&A'[14] where the authority explained what exactly happened.

The Authority has no reason to believe that it is the target of the investigation or that the investigation will materially adversely affect the operations or financial condition of the Authority or the transactions contemplated by the Resolution, the Trust Agreement and this Official Statement, or would adversely affect the validity or enforceability of the Resolution, the Trust Agreement or the Series 2014 Bonds.
