Big R Bridge helps Red Rocks rockers rock on

May 19, 2015


Red Rocks Amphitheatre is a 9,500-seat, world-renowned outdoor concert venue near Denver, CO, providing a unique experience for hundreds of thousands of fans each summer. When the popular park needed a new stream crossing at Gate #2, a pre-engineered and prefabricated solution from Big R Bridge earned rave reviews.


Truss design with weathering finish a real “natural”
The Big R design team, in nearby Greeley, CO, recommended a Warren Chorded Truss style with a naturally-weathering steel finish that just fit in beautifully with the iconic park setting.

About naturally-weathering steel
Big R Bridges are available in a variety of finishes: Weathering, Painted, Hot-Dip Galvanized or Metalized. A weathering steel superstructure is an economical choice, with a unique appearance that complements outdoor settings. Weathering steel naturally oxidizes to provide a protective patina that does not require painting. The color will vary regionally from dark brown to orange tones. Many bridge engineers choose weathering steel for its environmental performance and economical benefits.

  • Reduced toxic emissions: No oil-based coating is used, which reduces emissions of volatile organic compounds.
  • No contaminated blast debris in habitats: Because the steel is not painted, no periodic maintenance blasting is required.
  • Cost savings of 10 percent or more initially and even more over the life of the structure: No painting and the durability of steel mean reduced costs.
  • Long life and high performance: Weathering Steel has been used on bridges for many decades and performs well in most environments.
