This photo pair features the bridge crossing over Rock Creek, near Park Headquarters near Mile 3 of the Denali Park Road. This creek was originally known as "First Creek" because it was the first major creek crossing when moving west into the park. The original bridge was built in 1923, but damaged by flooding in 1930. By 1934, the bridge structure featured in the 1958 photo was built and stood for 25 years. The bridge in the second photo was built in 1959 and although it still stands as of 2013, it is slated for replacement.
