Trihydro + WYDOT Receive Engineering Excellence Award for Laramie Project
News item-01

Trihydro Corporation (Trihydro) and the Wyoming Department of Transportation (WYDOT) were jointly awarded the Wyoming Engineering Society (WES) 2018 President’s Project of the Year Award for the Laramie Streets - Union Pacific Railroad Overpass Project. Each year, the WES competition recognizes excellence in engineering and surveying projects that benefit the State of Wyoming and its residents. The 2018 competition results were announced on February 7, 2019 during the WES Annual Convention in Cheyenne, Wyoming.

About the Project
The winning project is a multimodal overpass, for which planning, design, and construction spanned 11 years.  Included in the scope for the project were roadway and shared-use path design, landscaping enhancements, water and sanitary sewer line relocations and upgrades, storm drain design, and demolition of the former Clark Street viaduct in Laramie, Wyoming.  The $23.5M project is also one of the largest capital construction projects to take place in Laramie outside of the University of Wyoming (UW). WYDOT, the project owner, and Trihydro, the project engineer, helped coordinate the various components of the overpass. The City of Laramie was also a major stakeholder in the project. 

On July 16, 2018, the City of Laramie celebrated the opening of the newly constructed viaduct. In addition to providing increased traffic capacity, improved functionality, safety, and a corridor from East to West Laramie, the four-lane bridge and connecting roadway provide a shared-use path for pedestrians, bikes, and other non-motorized transportation.  The new bridge is an aesthetically pleasing connection between West Laramie and downtown, and connects businesses with the City and UW.  It also links Laramie’s existing shared-use path infrastructure on the east and west sides of the bridge. 

"[This is]… a state-of-the-art bridge," WYDOT Chief Engineer Gregg Fredrick said during July’s opening ceremony. "But this bridge is about more than engineering, it's about community. This bridge connects a community."  

Trihydro’s engineers and environmental specialists had a special connection to this project, since many of the company’s 150 Laramie-based employees commute over the bridge daily to the company’s headquarters office in West Laramie.  

“We’re always proud to contribute to projects in our local communities,” said Claudia Torrence, Trihydro’s senior engineer and project manager. “This project hits particularly close to home because many of us get to use the bridge every day and see its positive impact firsthand.”

Based on the impact that this project has on Laramie residents and through traffic, the project team thoroughly considered the corridor’s purpose and need, design criteria, environmental impacts, context and constraints within the study area, as well as public and agency comments and concerns. The project used innovative modeling technologies and underwent a Value Engineering review to ensure the best solution for all stakeholders.

The viaduct’s improvements in access, connectivity, and mobility provides long-term benefits to local businesses, opportunities for reinvestment in the community, and, ultimately, employment rates as the location of the overpass will likely result in expansion of downtown Laramie northward, according to the City of Laramie
