So they just scrapped out the old bridge? Thats great they were able to reuse the riveted truss, but the pin-connected truss should have been in turn relocated and reused in a different location, perhaps for pedestrian use.

The former Meeker County bridge 5388 has been installed at Lake Louise State Park, replacing the old pin-connected high truss. The new bridge number is R0529. Lower chords, floorbeams and stringers were replaced, upper steel blasted and painted and a new concrete deck installed. We inspected this bridge on 10/7/2014 and it looks to be in very good shape.

I just noticed that this bridge is being replaced with another bridge relocated from Mower County. This is disappointing to me, because even though the bridge being brought in is historic, this one is far more so, in that it's older with design characteristics that were long gone by the time this bridge's replacement was built. Goes to show you that bridges located inside parks aren't safe either. It seems to me that this is a narrow one-lane road that will never see heavy truck traffic, and the current bridge would easily handle any traffic crossing even with just a light refurbishment and repainting. I was happy to see that the 1935 bridge was being preserved, but I'm certainly not happy to see that it is replacing another truss with far more historic value. The replacement bridge is a 1935 riveted polygonal Warren pony truss (see link below) that is two lanes wide and would be far more suited for restoration and use on a lightly traveled rural two-lane road. It is far more substantial than what is needed here, to say the least. This is a situation where both bridges could serve their justifiable purposes and be allowed to live on, but apparently not everyone thinks so.
