North Tarrant Express

The North Tarrant Express is dedicated to improving mobility along north I-35W, northeast I-820 and SH 121/183 Airport Freeway through a regionally supported managed lane system.

Construction began in October 2010 on the first project. In addition to the design, right of way and utilities, the project will rebuild and expand 13 miles along I-820 and SH 121/183 from I-35W to the SH 121 split. This $2.02 billion project will rebuild the existing four to six main lanes, add four toll-managed lanes, plus frontage roads and auxiliary lanes to approximately double the existing capacity. The project will provide an additional value of approximately $450 million for operations and maintenance through 2061. Two additional non-tolled main lanes which will also be added no later than 2030 at no additional cost. This public-private partnership brings 2/3 private funds with 1/3 public funds to complete this 13-mile corridor in five years. It is estimated to be complete by 2015.

In the next few months, TxDOT will evaluate a North Tarrant Express Mobility Partners submission for development of approximately 10 additional miles of Interstate 35W within the ultimate 36-mile NTE corridor.
