The Dresbach Bridge is very ordinary and nondescript for such a major Mississippi River crossing. Of all the places that a signature bridge could have been built, this would have been the place.

The river crossing at La Crosse is nothing short of amazing. The Black River joins the Mississippi River just south of this crossing. The result is a large number of channels, sloughs, wetlands, and lakes. The river itself is over 3 miles wide, and I-90 has several smaller bridges leading up to this span over the main channel. The I-90 bridge is the start of one of the most scenic sections of the Great River Road between La Crosse and Winona. The only other part of the Great River Road that can rival this section is the Palisades area just north of Alton, IL.

The Dresbach Bridge has a number of problems. First, it is a very narrow bridge for being a major freeway river crossing. The outside shoulders are only 3-1/2 feet wide, and the inside shoulders are only 2 feet wide. There is no room for a stalled vehicle to park, nor is there room for emergency vehicles to reach the scene of accidents. Second, the bridge has a very sharp corner on the Minnesota end of the crossing. Third, there are a number of very busy exit and entrance ramps near this sharp corner, one that routes US-14 and US-61 into the city, and another that serves a very popular rest area and riverside park. Finally, the bridge is built with a non-redundant design. That is, if any one of the major structural steel members fails, the entire bridge is likely to collapse. That is not good, rather, a bridge should be able to survive the loss of any one beam or brace.

MN-DOT has been leading a study of alternatives to upgrade the Dresbach Bridge. All of the alternatives feature a wider bridge and extensive interchange work on the west end of the river crossing. One alternative suggests a twin bridge, another widening the existing bridge, while yet another suggests a new cable stayed bridge. Price estimates are in the $50-million to $100-million range.

The photo at the top of the page is taken from the boat landing on the Minnesota side of the river, just below the highway rest area and just south of the bridge. The photo directly above was taken from the edge of the river near the rest area on the north side of the bridge. There is a lot of vegetation in this area, so you have to sneak photos in where ever you can.

Another photo from the boat landing parking lot under the Minnesota end of the bridge. Notice how far the bridge continues after reaching the opposite shore. The bridge crosses a narrow island, and then crosses the east channel of the Mississippi before returning to land.

Another view from the rest area parking lot shows how the bridge deck sits at tree top level.

This view of the main span was taken from the parking lot at the US Army Corps of Engineers Lock & Dam #7, which is just north of the rest area. Photo was taken on a typical overcast winter day. The water looks very cold, but it did not freeze below the dam for several miles during the winter of 2006 and 2007. The water was frozen above the dam.

Here is a photo take through the windshield while heading westbound on I-90. This is the start of the Dresbach bridge. Note that it is a single span with only a guard rail between the two sets of lanes.

This photo again shows the westbound climb towards the peak of the bridge. While the profile shots of the bridge do not show that much of a hump, it really feels like a large hump in a moving vehicle.

The photo above is taken heading westbound towards the Minnesota end of the bridge, right over the main channel of the river crossing. Note that the steep bluff forces the sharp curve and the rocks leave no room for additional construction. The photo below shows the eastbound crossing. The bluffs in the distance are on the far east side of La Crosse, about 4 miles in the distance.
