South End of Tollway To Be Closed Late Evening of June 22 through early morning on June 25
Delays expected; Motorists encouraged to plan ahead and seek alternate routes
 On the night of Friday, June 22, starting at midnight until Monday, June 25, at 5:00 a.m., the south end of the Dallas North Tollway will be closed northbound from IH-35E to Mockingbird and southbound from Northwest Highway to the southern end of the Tollway. The Cedar Springs Road Bridge, in both directions, will also be closed during this time. On Monday morning, the Tollway and the Cedar Springs Road Bridge will both be open to two-way traffic.
NTTA construction crews will be demolishing the old Cedar Springs Road Bridge, placing drainage lines under the Tollway to prevent flooding during heavy storms, hanging bridge beams for the bridge over Oak Lawn Avenue and performing pavement repairs on the IH-35E ramp northbound to the Tollway.
On the Tollway, southbound motorists will have to exit at Northwest Highway or sooner.
The southbound entrance ramps at Lovers Lane, Mockingbird Lane and Lemmon Avenue will be closed. Southbound entrance ramps at Walnut Hill, Royal Lane and Forest Lane will also be closed due to the short distance before they have to exit.
Northbound Tollway entrances at Harry Hines Boulevard, IH-35E and Wycliff Avenue will be closed and northbound traffic will not be able to enter the Tollway until Mockingbird Lane. Signage will be placed on the Tollway in several places to notify motorists of the closure.
During these closures, motorists should plan ahead, seek alternate routes and expect delays. IH-35E and Central Expressway (US 75) serve as viable alternatives to the Tollway during this time. All work is subject to weather conditions and will be postponed, if necessary.
The temporary closing of the Tollway is part of a $50 million upgrade and reinvestment in the southernmost section of the Tollway and the Wycliff Toll Plaza. More than 40 years old, this section of Tollway requires the following renovations: pavement replacement, improved overpass bridges, the widening of Oak Lawn Avenue as it approaches the Tollway, new ramp access to Oak Lawn Avenue and the construction of a new Wycliff Toll Plaza.

All lanes of traffic are scheduled to be open to traffic in the spring of 2008. Upon completion, the improvements will provide streamlined traffic flow, additional safety enhancements, a state-of-the-art toll plaza, and will relieve traffic congestion.
