Progress Moving Ahead on Dallas North Tollway-George Bush Interchange

Bridge beams and barrier wall work to begin at DNT/PGBT Direct-Connectors

June 1, 2016… It’s hard to believe that this marks one year from the beginning of the Dallas North Tollway Improvements Project construction. Drivers have seen many changes throughout the corridor, but more are on the horizon. This summer major work near the DNT/PGBT Interchange area will begin to expand the intersection and improve the driving experience.

On the weekend of June 10, as half of the bridge at Tennyson Parkway is taken down (for more info see the other article), crews near the DNT/PGBT interchange will add more cranes to the Plano skyline.  These cranes will be used to set beams for the expansion of the direct-connectors from PGBT to northbound DNT and southbound DNT to PGBT.

To facilitate the work, closures will be required on the direct-connector ramps and various closures along the Dallas Parkway and Plano Parkway.  Crews will also remove the concrete barrier from the side of the connectors. The barrier removal will make room for the new lanes being added to both ramps.

As crews add lanes to the current direct-connectors, they will also be building new entrance and exit ramps south of the Park Boulevard intersection.  These new ramps will separate traffic on the main lanes and the direct-connectors, eliminating the back-up that is currently caused by merging traffic during peak driving times. These new “braided ramps” need space to be built! To make room near Park Boulevard, the northbound lanes of Dallas Parkway are being shifted to the east of the current frontage road. In early summer, the southbound braided ramp work will begin in that area.
