DNT Improvements: Work on Intersection Bridges Continues Into September

During the summer, Dallas North Tollway drivers likely noticed work on the DNT bridges throughout Plano as crews remove concrete bridge rails and bridge overhangs in the area.

The DNT Improvement Projects work has now progressed to the southbound sides of the bridges. To minimize impacts to traffic, crews will perform this work during overnight hours to allow for city streets closures and protect the public from debris. In the coming weeks, drivers can also expect to see crews working on the  bridge elements that support the additional lanes. Visit ProgressNTTA.org for information on traffic shifts and closures.

The DNT Improvement Projects include the reconfiguration of the existing direct-connector ramps on the north side of the DNT/President George Bush Turnpike interchange. This reconfiguration will add a lane and include improvements to the Park Boulevard exit from PGBT. Access between Parker Road and Windhaven Parkway will be improved by modifying the ramp locations and adding new entrance ramps north of Windhaven Parkway.

The Improvement Projects, funded by toll revenue, are scheduled for completion in early 2018. Motorists should be aware a lowered 60 mph speed limit is posted and enforced in these work areas along the DNT between Bush Turnpike and Sam Rayburn Tollway.
