Texas Department of Transportation—I-35E Managed Lanes Project

The $1.4 billion I-35E Managed Lanes Project transformed a 30-mile corridor in Dallas and southern Denton counties to accommodate growth in one of North Texas’ fastest-growing areas. The 35Express project, as it is known, converted two concurrent, high-occupancy vehicle lanes into dynamically priced, reversible managed lanes, and provided additional main lanes for 21 miles. Also, the project improved safety by adding a second bridge over Lewisville Lake.

The two reversible lanes feature dynamic pricing, which keeps traffic moving at least 50 mph. The project enhances air quality and also improves quality of life and by offering motorists an option to avoid congestion, increasing their flexibility to manage work and family schedules. The project also encourages car-pooling by offering half-price managed lane discounts during peak hours for registered vehicles with two-plus occupants, a much-needed option as Denton County’s population rises.
