Construction, maintenance and management of a 21.4 km section of the Lyndon B. Johnson (LBJ) Expressway.
Located between IH-35E and US-75, and interstate IH-35E, between Loop 12 and the LBJ, north of Dallas (Texas).

Construction, maintenance and management of a 7.4 km section of the Lyndon B. Johnson (LBJ) Expressway, located between IH-35E and US-75, and interstate IH-35E, between Loop 12 and the LBJ, north of Dallas (Texas).
Construction commenced late in 2010 with a budget of 1.12 billion euro. The first segment, measuring 5 km, came into service in December 2013, and the section of Interstate 65 between Josey Lane and Interstate 35E, the southern part of beltway 12, and the northern part of I-35E before Valley View Lane, came into service in August 2014.
This phase includes two elevated TEXpress lanes in each direction as well as additional side lanes for smoother traffic flow. Work is scheduled to be completed and the road fully opened late in 2015.
It received the ARTBA Globe award for Environmental Excellence due to its notable efforts to maintain environmental protection standards in all phases of construction. The LBJ Express environmental team received distinctions for the comprehensive environmental protection programme and the soil and groundwater management plan, which were applied to manage heavy metals discovered during construction. The team also reused millions of cubic metres of excavated soil in other phases of the project and donated soil for use in other projects in the city of Dallas and the state of Texas. They also analysed, purified and recycled groundwater in order to palliate the drought problems in the north of the State.
The New and Improved LBJ: The LBJ Express
The LBJ Express is a public private partnership, with limited funding from taxpayer sources. The project will incorporate dramatic improvements to Interstate 635 (IH-635) and Interstate 35E (IH-35E) in Dallas County featuring rebuilt main lanes, a continuous frontage road system, and 13 new miles of managed toll lanes.
An Innovative Highway Solution
The LBJ Express is an ambitious project that will transform approximately 17 miles of roadway in a five-year time period by working on several construction areas simultaneously.
During project construction, traffic must be moving at all times, with at least four lanes open in each direction and an exit always available during peak traffic times.
The current capacity of today’s LBJ Freeway will be nearly doubled with the creation of up to six new express managed lanes on IH-635 and four new managed lanes on portions of IH-35.
Managed Lanes Explained
A toll road charges a fixed price that remains constant at all times of day but does not guarantee predictable travel times, thus keeping traffic moving.
Drivers in managed lanes, or express toll lanes, will see tolls adjust based upon the average speed or number of drivers who want to use the express lanes. During non-peak driving times, the average tolls will be less than during rush hour. Dynamic pricing provides a traffic management tool that will guarantee drivers a predictable, higher-speed commute.
The conceptual design of the project will give drivers the option to pay a toll and use the managed lanes system, or utilize the newly constructed general purpose lanes.
