This one comes from the Franklin Square Lithographic Co.
About two decades later, William Henry Jackson, shot this photograph of the bridge for the Detroit Publishing Co.
Here are two details from this image. They show a casual mingling of sail and steam vessels. The tugs that you see are pretty much the same as the ones in use through most of the 20th century and, for all I know, in this one as well.Jackson took this photo at about the same time.
Here's a detail from it. The boat is very much like the broad, shallow-draft craft of the Dutch harbors.These next shots come from anonymous photographers working for Detroit Publishing at the same time.
Although this shot does not show the bridge, I couldn't resist including it.
