I-635, also known as LBJ Freeway, carries more than 200,000 vehicles per day. The overall project goal is to improve mobility and reduce traffic congestion in this main Dallas-Fort Worth commuter corridor. The completed project is also expected to improve safety and mobility within the I-635 corridor as well as improve access to existing roadway connections.

The project involves significant reconstruction and improvements to the I-30 interchange and a section of I-30 from west of Gus Thomasson Road to east of N. Galloway Avenue in Dallas County, Texas. Construction will include the addition of a general purpose lane in each direction and rebuilding the existing managed lane in each direction to this critical section of I-635.

The project will also feature the construction of continuous frontage roads with numerous intersection improvements for the frontage roads and cross streets to function more efficiently, including the design and construction of a signature bridge at the Skillman/Audelia intersection.
