Loop 12/IH-30 Interchange Expansion


Loop 12/IH-30 Interchange Expansion | Irving, Texas
Client: Texas Department of Transportation, Dallas District

Huitt-Zollars designed this project to replace the existing IH-30 mainlanes with new mainlanes as identified in the Loop 12/IH-30 ultimate design schematic. The project’s focus filled the gap between two construction projects with ultimate mainlane configuration that meets the future four-level interchange criteria. Huitt-Zollars designed the bridges to accommodate future direct connector, HOV lane, and railroad bridge bents. This project also required the design of a temporary three-lane bridge over Loop 12 and the Union Pacific Railroad in order to facilitate traffic control sequencing.
