Since 1953, HNTB has supported the North Texas Tollway Authority (NTTA) and its predecessor, the Texas Turnpike Authority, with the successful delivery of tollfacilities across north Texas as both general engineering consultant and program management consultant. Throughout this partnership, HNTB has assisted NTTA in delivering over 1,000 lane-miles. Specifically, HNTB’s work on the Dallas North Tollway began in 1965 and has continued through the conversion to all-electronic tolling and the implementation of numerous expansions and widening projects.

As an extension of staff, HNTB provides capital projects programming; contract administration; environmental document review and oversight; design reviews; program controls; community outreach; landscape design and implementation oversight; oversight of right-of-way acquisition and utility relocation.
Through other contracts with NTTA, HNTB has also provided public involvement and project communications; construction management oversight; trust agreement services; annual inspections; engineering reports; IT lane audits; pursuable transaction services; back office system replacement and toll system support.
