Looking at the picture, itís clearly a reused truss from somewhere. The portals seem to indicate a date earlier than the 1920s build date. To me, it almost looks like some of the reused Santa Fe trusses in Missouri and Kansas, indicating it could have been a railroad span

On a side note, my dad worked construction and helped work on 12th Avenue when they replaced the bridge. Small world, isnít it?

TIL--gephyrophobic - having a profound fear of bridges

The link mentions crossing at the roundhouse, the remains of which are still visible. The tracks on the east side are the older of the two, so the truss was probably over the east set of tracks.

I believe this is a link to more info about this bridge.


built 1928

replaced 1976

Crossed the tracks between 20th and 23rd streets, so it must have crossed the set of tracks just west of Dakota Drive.

Phrase of the day: "Harrowing ride" 8^)
