Surprise! This bridge over the Susitna River appears without warning, so if you want to stop and see this huge drainage, slow down and pull off the road at either end. Alaskans call it the Big Su. We fish it, paddle it, and snow machine its frozen braids. Bush pilots even navigate by this river.
The Susitna River winds its way over 313 miles of Southcentral Alaska; this old railroad bridge crosses the water on the eastern edge of Denali National Park. Dating back to 1921, the bridge today is on the National Register of Historic Places.
