Project Summary

After seasonal floods washed away the existing timber bridge, the USDA Forest Service selected a durable GatorBridge® to replace it. This popular hiking trail needed a bridge that would be longer, stronger and lighter than the one the 2006 floods washed out. The new aluminum bridge spans the South Fork Stillaguamish River in Mt. Baker Snoqualmie National Forest to the base of Big Four Mountain. The GatorBridge® solution was chosen for its quick turnaround time, light weight and speed of installation even in an area that was poorly accessible.
