ABKJ’s Mount Si Bridge Replacement project was named the best medium-span steel bridge in the nation in the 2009 National Steel Bridge Alliance Awards. The honor was announced at the World Steel Bridge Symposium in San Antonio, Texas.
The Mount Si Bridge serves as a vital link across the Snoqualmie River for local residents and as a gateway to regional outdoor activities within the Mount Si Natural Resources Conservation Area. This $10 million structure replaced a deteriorating bridge that was more than 90 years old. The new bridge utilizes 406 tons of steel and is 240’ long with an average width of 43’.
