BACKGROUND
Our team at infraTECH is at the forefront of delivering structural engineering solutions for the widening of US 75 from US 82 to SH 91 and N Loy Lake Rd to US 82. As Prime Consultant, infraTECH is leading this extensive $300 million infrastructure upgrade. The project includes the design and construction of 15 bridges, 2 ½ miles of Mechanically Stabilized Earth (MSE) walls, and over ½ mile of soil nail retaining walls—all essential for enhancing roadway capacity and long-term stability. With approximately 6 miles of roadway improvement and reconstruction, our focus is on delivering innovative, durable, and resilient bridges and wall systems that support the widening of main lanes, frontage roads, and interchange reconstructions.
By integrating advanced engineering techniques, we ensure that each structure is designed to withstand increased traffic loads while optimizing safety and efficiency for the region’s growing transportation network.
