The current MN-25 is the third bridge to cross the Mississippi River at Monticello. The first was a swingspan, pictured above in a period postcard. That bridge stood from 1891 to 1930. A steel truss bridge stood from 1929 until 1987. Remains of that bridge still exist in the parking lot of a local bar and grille on the east side of the river. The remains include two bridge joints, the deck plate, and a sign indicating where the center line of the bridge once stood. A driveway leading into the bar and grille appear to follow the original highway alignment.

These two photos are the remains of two joints that were salvaged from the old bridge. They are sitting on concrete pads at the edge of a parking lot along with a pair of park benches.

The photo above is the bridge plate from the old bridge. It is mounted in a monument near the east end of the old structure. The photo below is the sign that marks the center line of the deck of the old bridge.
