This weekend's roadtrip took us by one of my work projects from 2005. It's the Summit @ Snoqualmie's Alpental Bridge. It's nearly 300 feet long with 10 feet of clearance between hand rails. It's in a beautiful area of the Mount Baker-Snoqualmie National Forest at the Alpental Ski Area.
Here's a few pics! Front view, down the back edge, and a view of the summit from the center.
