The North Texas Tollway Authority will begin an improvements project on the Dallas North Tollway (DNT) between Harvest Hill Road and Interstate 35E in April 2017. The two-year project will include replacing the tollway’s center barrier and pavement. The work will occur within the cities of Dallas, University Park and Highland Park.


To minimize traffic impacts, the improvement work will be conducted during off peak hours at night and during some weekends. Some temporary lane and ramp closures may be needed.


Throughout the project, NTTA plans to keep you informed. We will do this through a variety of communications tools including e-newsletters, lane and ramp closure announcements, information posted on our website,, traffic advisories, social media posts and when needed, community meetings.
