Partial Demolition of the Tennyson Parkway Bridge Scheduled for June 11 Weekend

Full Closure of the DNT Main Lanes to occur during closure

Crews have been preparing for work on the Tennyson Parkway Bridge over Dallas North Tollway since last July when temporary signal lights were installed at the Dallas and Tennyson Parkways intersections. In March, all traffic on Tennyson Parkway was shifted onto the southern portion of the bridge. Crews are now ready to take the next major step—demolishing the northern portion of the bridge.

The bridge will be demolished and rebuilt in two parts to keep traffic moving on Tennyson Parkway and complete construction on schedule. The newly built section will accommodate additional lanes on the DNT. The first phase of demolition will take place during the weekend of June 11.

WHAT WILL HAPPEN?

Beginning Friday, June 10 at 11 p.m., crews will begin a full shut down of the Tollway between SH 121 and Spring Creek Parkway, including the direct-connector ramps from the Sam Rayburn Tollway to southbound DNT. Police officers will assist with the closing and be stationed at all entrance ramps through the closure to prevent drivers from entering the construction area.

Once the Tollway is closed to traffic, crews will begin to demolish the bridge. The old concrete will be removed and the area will be cleaned up prior to reopening the Tollway before 5 a.m. Monday, June 13. Should there be inclement weather, this work will be rescheduled.

During this work, Tennyson Parkway will remain open to traffic. The structures are separated and demolishing the north portion of the bridge does not impact traffic on the southern portion.

BRIDGE AFTER DEMO

Following the demolition, crews will immediately begin work to build the new northern portion of the bridge. This will take approximately eight months, weather permitting. Once the north bridge is completed, traffic will shift onto the new bridge and the old bridge will be demolished and rebuilt.
