Best Overall Project of 2008

Maroon Creek Bridge
Submitted by BTE/Atkinson JV

This 670-ft-long, single-cell, cast-in-place balanced cantilever concrete bridge accommodates vehicle, bus and bicycle traffic, with a design that is sensitive to its environment and mimics the adjacent 1890s vintage railroad trestle. It is the first cast-in-place concrete bridge built in the balanced cantilever segmental method in Colorado since four of them were built on Vail Pass in the 1970s. The project team endured severe winter weather at the 8,000-ft elevation with an overextended labor market, but completed the project within contract time. Various changes to the project allowed for improvements to the bridge while remaining within the original budget.
