The Texas Department of Transportation (TxDOT) has embarked on a monumental $1.45 billion project. The initiative aims to address the surging demand on the I-35 corridor by introducing a cutting-edge viaduct, thereby augmenting the thoroughfare with three additional lanes in each direction. The project, overseen by Ferrovial Construction U.S. and Webber LLC, leverages Bentley’s iTwin platform, ushering in digital twin technology to enhance collaboration and streamline information exchange, according to Bentley Systems dated February 09 2024.

A key trade route through the U.S. between Mexico and Canada, I-35 is one of Texas’ most congested roadways. Traffic volume is predicted to grow by 50% over the next 10 years.

The I-35 Northeast Expansion Central Project encompasses a design-build approach and spans approximately 9.5 miles, integrating non-tolled enhancements along I-35. The focal point of the undertaking involves the construction of a remarkable 21.8 miles of innovative viaducts, two strategically positioned interchanges, and a sophisticated drainage system. TYLin, a pivotal member of the Alamo NEX Construction Team, assumes the role of Engineer of Record for 40% of the project.

Digital technology, exemplified through Bentley’s suite of applications, facilitated precise clash detection, averting 3,530 potential collisions. The platform also identified and addressed visibility concerns, providing the construction team with invaluable material information. This approach significantly streamlined the construction process, resulting in substantial time and cost savings.

“Using 3D Modeling simplifies our work and saves up to 25% on design time,” said Marta Raya, chief project manager at Ferrovial and Alamo Nex Construction.

Carlos Gonzalez, vice president, Design Operations Lead North America Ferrovial Construction: “The achievement of this bridge will increase the traffic time efficiency by 45%. The incorporation of digital twin technology into our workflow has been transformative. It has not only enhanced efficiency but has also positioned us at the forefront of technological innovation in the construction industry.”

The project, which broke ground in 2022, is slated for completion over a six-year timeline, promising to redefine the I-35 corridor, enhance traffic management, and elevate the overall transportation experience for the region.
