Apparently good news here. After some uncertainty over cost, MNDOT will rehab the main steel truss spans of the old bridge after all, but they'll completely replace the approach spans in what appears to be a compromise to keep the overall project within budget. They will be replaced one at a time to maintain contractor access for rehabbing the main steel truss spans at the same time. First Minnesota end, then Wisconsin. So it will indeed wind up as an old/new couplet of 1-way bridges.

I was just through Winona, and I drove across the new westbound bridge. It has opened to 2-way traffic until work on the old bridge is completed and it's reopened for eastbound traffic in 2019. Demolition work has begun on the west (Minnesota) approach spans.

Will Minnesota DOT renege on bridge promise?

Here we see a fine two-bridge solution under construction. The new concrete box-girder bridge will carry westbound traffic, while the historic truss bridge will carry eastbound traffic. Temporarily, the new bridge will carry both directions, while the old bridge is closed for a thorough rehabilitation. The slim profile of the new bridge will not interfere much with sight lines of the historic truss bridge, especially from the south and the Downtown Winona riverfront.

I only wish such an arrangement could be worked out for a couple of other historic bridges facing demolition, such as Savannah-Sabula. http://bridgehunter.com/il/carroll/8600001777/

It's good they're keeping the old bridge. In MN, it's somewhat rare to see an old bridge and a new bridge side by side. The last old/newer bridge combo I can recall was the I-94 bridge over the St. Croix river that lasted till the mid-90's when the old bridge was demolished.

Sounds like they want a two bridge solution here, with a new girder bridge taking some of the load off this historic bridge. http://www.dot.state.mn.us/d6/projects/winonabridge/docs/ea....
