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.
