Bridge Documentation

This bridge no longer exists!

This historic bridge is at risk for demolition and replacement just for pedestrian use!

This bridge is a beautiful example of a pin-connected Pratt truss bridge. This type of bridge was the cornerstone of the late 19th Century and early 20th Century. They were once common in this country. However, surviving examples of these historically significant and beautiful truss bridges are drastically falling across the country due to demolition. This particular multi-span example is traditionally composed and a good representative example of its type. Its trusses retain historic integrity with no major alterations. One somewhat odd detail is that the northern span is slightly larger (and has one more panel) than the southern span.

This bridge was built in 1901 to provide vehicle access to Sylvan Island. It was closed in the 1960s. The island later became a park and the bridge was converted for pedestrian use in 1995.

In 2013, the bridge was closed due to deterioration, which cut off public access to Sylvan Island, which was a pedestrian-only park. Current plans are to demolish the historic bridge and replaced with a modern non-historic bridge. This would represent the loss of a visually attractive and historically significant bridge that provided an iconic gateway function to a park.
