This photo of the suspension footbridge was taken in 1998. This bridge (as well as the automobile bridge main entrance) were swept away 9 years later.

During the Great Coastal Gale of 2007, a twenty-mile stretch of Interstate 5 was closed between exits 68 and 88 because of flooding from the Chehalis River, causing the roadway to be under about 10 feet of water.

During this flood, the Chehalis river swept away the bridge connecting the highway and Rainbow Falls state park.

This park was developed by the Civilian Conservation Corps in 1935. Rustic log structures from the CCC program are still present for visitors.
