The Dallas North Tollway (DNT) is being expanded to four lanes in each direction. In order to continue the expansion of the Dallas North Tollway fourth lanes, the bridge at Tennyson Parkway in Plano is being demolished and rebuilt. The full closure of Dallas North Tollway is needed to allow crews to begin demolishing the Tennyson Parkway bridge safely. Allowing crews to have continuous access over a weekend means work can progress quicker without further impacting daily commuter traffic during the week.

Beginning Friday, June 10 at 11 p.m. crews will start arriving to prepare for the full closure of the Dallas North Tollway that is set to begin at midnight. Once the closure begins, the following areas will remain closed through 5 a.m. Monday, June 13.

  • All northbound lanes of the Dallas North Tollway from the Spring Creek Parkway exit to the Headquarters Drive entrance ramp
  • All southbound lanes of the DNT from Gaylord Parkway to the Spring Creek Parkway entrance ramp
  • The east- and westbound direct-connector ramps from the SRT to southbound DNT
  • The northbound DNT direct-connector ramp to east- and westbound SRT
  • The northbound entrance ramp from Spring Creek Parkway
  • The northbound exit ramps at Legacy and Headquarters Drive
  • The southbound entrance ramps from Gaylord Parkway, SH 121 and Legacy Drive
  • The southbound exit ramps to Legacy Drive and Spring Creek Parkway

Police officers will be stationed to assist with traffic control. For your safety and our crew’s safety, please do not try to drive passed barriers to access Dallas North Tollway. The barriers are in place because debris from the demolition will be falling onto Dallas North Tollway main lanes.

The good news is Tennyson Parkway will be open to traffic. The bridge structures are separated; as demolition occurs on the northern bridge, the southern bridge will remain open and operational.

Although Dallas Parkway will remain open during this operation, delays are expected. If you are traveling in that area, please see the closure map and plan to seek alternate routes accordingly.

In case of inclement weather, this work will be rescheduled.
