SH 121, Sam Rayburn Tollway, NTTA

(January 2008 – May 2013)


NLA served on the team providing administrative support. This project authorized NTTA to design, build, operate, and maintain SH 121 in Collin, Dallas, and Denton counties for around 50 years. The six-lane tollway extends 26 miles from the southwest to northwest and links the DFW Airport to growing communities in Dallas and surrounding counties.
