Starting mid-February, a traffic lane shift will occur on the Dallas North Tollway under Interstate 635 to allow for the construction of new center columns for a future I-635 bridge. This lane shift along the Dallas North Tollway will be in place for an estimated two to three months.
This work is part of the Texas Department of Transportation’s LBJ Express project in north Dallas.
LBJ Express crews will re-construct the I-635 bridge over the Dallas North Tollway and portions of the connecting ramps within the interchange. Closures of the Dallas North Tollway will be needed occasionally to accommodate work. Most of the closures will be scheduled at night and on weekends during off-peak hours whenever possible. You can find real-time road conditions, scheduled lane closures and other traffic advisories at www.lbjexpress.com and www.NTTA.org.
The LBJ Express project is being developed and constructed by the LBJ Infrastructure Group UC, a private developer, under a comprehensive development agreement with the Texas Department of Transportation. According to www.lbjexpress.com, the project will double the capacity of I-635 between U.S. 75 and I-35E. Seventeen miles in length, the roadway will contain rebuilt freeway lanes and new express managed toll lanes.
Managed lanes are part of the North Texas Region's Metropolitan Transportation Plan and are facilities that add lane capacity to existing freeways by combining high occupancy vehicle (HOV) and new express lanes to improve freeway efficiency. At present, the NTTA does not have any managed lane projects.
A segment of the new LBJ project will cross over the Dallas North Tollway within the next couple of years. The NTTA is working early with the LBJ Express project team to minimize future interruptions to travel on the Dallas North Tollway. Currently, there is no firm timeline for the New LBJ project construction over the Tollway.
