Bridge Design

Sigma’s bridge design experience assures that all projects, regardless of size or complexity, will conform to agency requirements.

They feature low cost, innovative solutions that will save our public and private sector clients millions of dollars, reduce overall construction time, and improve long-term performance of the finished product. Sigma worked on a large scale project, Boulder City Bypass, which is procured as a $225M design-build and includes nine bridges. The project consists of the construction of approximately 12 miles of Interstate freeway to ultimately link Mexico City to Canada by way of Phoenix and Las Vegas.
