Full Closure of the Dallas North Tollway

Demolition of the Tennyson Parkway bridge 
11 p.m. Friday, June 10 through 5 a.m. Monday, June 13 

The current Tennyson Parkway bridge over the Dallas North Tollway cannot accommodate the new DNT fourth lane. In order to continue the construction of the DNT Improvement Projects and allow traffic on Tennyson Parkway, the bridge at Tennyson Parkway will be demolished in two phases, beginning with the north section. Once the new north section of the bridge is built, traffic on Tennyson will be moved onto the new bridge and the southern section will be demolished and rebuilt.  Closures needed to complete the demolition of the north portion of the bridge are below.

Beginning at 11 p.m. Friday, June 10 through 5 a.m. Monday, June 13 (Continuous closure) ·       

  • All northbound lanes of the DNT 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  

Note: Tennyson Parkway over the DNT will be open to traffic.  The structures are separated and therefore demolishing the north portion of the bridge will not impact traffic on the southern portion.
