The original Maroon Creek Bridge was erected in 1881 to carry freight trains to the booming silver mining industry in the mountains surrounding Aspen, Colorado. Widened to carry modern day vehicular traffic, the structure was one of the oldest and most outdated bridges still in service in the country.
The new Maroon Creek Bridge is a signature bridge that gracefully complements the surrounding environment and the historic structure standing nearby. Built with a 270' main span in the cast-in-place balanced-cantilever method, the construction of this bridge protected the sensitive wetland and blue-ribbon trout stream below.
