The MN-25 bridge is a rather run of the mill 4-lane concrete girder bridge that we will find commonly crossing the Mississippi River on shorter river crossings as we head north. This bridge replaced a 1930 steel through truss bridge, which replaced an 1891 swingspan.
I found it interesting that the City of Monticello had cameras set up around the bridge. They also posted signs to remind people that they were being watched. I happened to take a picture of one of these cameras, and found that it was actually a utility light set behind a metal cage. Within minutes of taking photos around the base of the bridge, a city vehicle appeared and the driver followed my every move through binoculars. There must not be much excitement in Monticello.
