Marsh Rainbow Arch Bridge

Its paired curved arches illustrate the patented bridge design associated with engineer James Barney Marsh and provide a compact architectural stop near the city center.

The photograph shows the actual Spring Street bridge. View it from permitted public approaches and check current signs before using any crossing route. This is a transport structure rather than a staffed attraction, so do not stop in a traffic lane or enter the creek banks without an approved path. Combine a brief look at the arches with a wider downtown walk.
