Mill Creek Tunnel, being built by the Southland/Mole joint venture for the City of Dallas, has moved into concrete lining operations after one of the largest hard rock tunnel boring machines (TBMs) ever used in the United States completed mining in July 2022. “Big Tex,” as the TBM was nicknamed, began mining with a 37.5 ft diameter before converting to a 32.5 ft diameter about 2 miles into the 5-mile-long excavation.
The project has received recognition from all corners of the engineering and construction community, including earning a “TECHNICAL INNOVATION OF THE YEAR” award from the International Tunneling Association (ITA), for Unprecedented In-Tunnel Diameter Conversion, of the Largest Hard Rock TBM in the U.S.
