UP/C&NW/CGW Hoffman Bridge over Mississippi River

401' Swing Span

Summer of 2011 when the Mississippi River was at a high water level.
The swing span has been replaced. The last rehabilitation was in 1982. But a swing span would have been replaced by a lift span in the 1980s. So it is not clear when it was replaced.

So St Paul Minnesota July 2008 Hoffman Swing Bridge open for river traffic Mississippi River. Got hit by a runaway barge about one year ago but they were able to repair. I'll see if I can find the pic.
A barge allided with a pier and sheared the top of the pier off. The truss remained attached to the pier remnant and thus it became skewed.

Trains has another view of the damaged pier.

The barge also had a "boo boo."

I don't know what the yellow flag signals to the oncoming train.

Andrew Koetz posted two photos with the comment: "Hoffman Swing Bridge in St. Paul, MN. during the 1997 flood of the Mississippi River. The first shot I took through a 20 X 60 spotting scope with a fixed optic, the second one I shot with my standard 50 MM lens on my Pentax K1000. In the second shot, the bridge is roughly about in the middle straight back over the second aircraft hangar."
