The Willard Munger Trail has a lot of fascinating things to see, but perhaps none are as beautiful as the St. Louis Bridge. It is a steel bridge that is approximately 150-feet long and 12-feet wide. It crosses the St. Louis river and is about 88 feet above the river. It was built in 1906. At one time, it was a part of the railway system that ran through the area, but now it is purely for your enjoyment along the trail. It offers a very scenic view of not only the river, but the river banks and forests beyond.
