Check your source. The interactive map becomes Zamora when I try to zoom in on a bridge to see exactly where it is. Addresses are not provided.

I believe that many bridges in the state of Michigan are in bad shape. You can tell that by looking at some of them. However. When you put a scale-able map in a story that shows you where deteriorated bridges are, it helps your case if the map is accurate. In Watersmeet (in the Western UP) a box pops up for the Crozer St. Bridge that lists daily crossings at 395. The "Crozer St. Bridge" is the bridge over the Middle Branch that carried Hwy 45 a hundred years ago. This bridge was replaced decades ago by a modern bridge carrying Hwy 45 across the Middle Branch. The modern bridge is located a very short distance east of the Crozer St. Bridge, and can be viewed from the Crozer St. Bridge. Today, the Crozer St. Bridge is a picturesque local bridge over a pretty little river, and it carries a low traffic residential street, not a US highway. The bridge that carries Hwy 45 may need work for all I know, I haven't gotten down and looked at it from below. However, it is most emphatically not 100 years old.
