I-635 Express Expansion

I-635 Express Construction

The LBJ Express project rebuilt one of the busiest and most congested highways in North Texas. Construction began in early 2011 and reached substantial completion almost four months early in September 2015. The project was designed and built concurrently, shaving several years from the project schedule.

LBJ Express provides improved mobility by almost doubling the existing roadway capacity and features a combination of four main lanes in each direction and two to three lane continuous frontage roads in each direction, three managed toll lanes in each direction that will use fluctuating, congestion managed tolling with a goal of keeping traffic moving at a minimum of 50 mph.

It is the first comprehensive development agreement (CDA) project signed in Dallas County. The joint project with LBJ Infrastructure Group (LBJIG) leveraged a $490 million TxDOT investment into $3.1 billion to build, operate and maintain the 16.5-mile project.
