These are notes that I am writing to help me learn our industrial history. They are my best understanding, but that does not mean they are a correct understanding.

1868,1892,1930,2012 BNSF/CB&Q Bridge over Mississippi River at Burlington, IA
"This is the first all-metal bridge to cross the Mississippi River. Bridge was built in 1868 as a single track. It was rebuilt in 1892 with a new superstructure, widened to support 2 tracks, and two truss sections were replaced with deck girder spans. The bridge was strengthened once again in 1930 to accommodate ever heavier rail cars....A US Coast Guard study found that this bridge was third among those that were struck most often by barges. It was hit 92 times between 1992 and 2001. As a result, BNSF is reported to be planning to replace the swing span with a lift bridge." [JohnWeeks] And in 2012 the lift span went into service.
"Spans: 6 – 246 ft long fixed through double track spans, 1 – 356.5 ft long swing span" [EngineeringPurdue]

Nathan Holth's comment on BridgeHunter0-2012 called this the "Ugliest Lift Towers In History." He must not have seen the BNSF bridge over the St. Croix River because it has the same Mickey Mouse Ears.
This partially open view gives a good view of the counterweight.
Loco Steve via PlaceAndSee, License: Creative Commons Attribution (CC BY) In 2008, the US Coast Guard declared the bridge a danger to navigable traffic. That means that federal funds could be used to replace it. Thanks to the 2008 recession and the subsequent American Recovery and Reinvestment Act of 2009, replacement work began in 2009. The approach trusses were also replaced by a different contractor. I wonder if the Feds also paid for the approach trusses. [I don't know why there are steel girder spans on both sides instead of a truss on the river side.]
The above is what I wrote in Apr 2022 when I could not find these notes because they did not have the "wwMiss" label. Fortunately, I found these notes before I published the 2022 notes so that I did not end up with duplicate posts. And I added the wwMiss label.
In case you were wondering; It is possible to catch the California Zephyr crossing the Mississippi at West Burlington, Iowa then drive twenty miles and catch the Southwest Chief crossing at Ft. Madison, Iowa. Well, at least it worked out that way for me - June 11, 2002.
Once again, the Birds-Eye View is the oldest view and it still shows the swing bridge. Bing's satellite image shows the 2012 bridge during construction and Google's satellite image shows it all done.
I didn't realize that it was so tricky to aim for the opening. Do they come in on an angle because of river currents? No wonder the Coast Guard wanted the movable span changed.

Robert Daly posted three photos with the comment: "The BNSF bridge over the Mississippi at Burlington, April 13 2013. It was built in 2010 to replace a former CB&Q bridge from the 19th century and is the newest rail crossing of the river."

When I saw the road in the foreground of Robert's first photo, I checked out the street view from it.

I was aboard Amtrak's California Zephyr #6 on Wednesday, and I snapped a few photos of the train crossing the Mississippi River after being delayed about 10-15 minutes for river traffic. Enjoy!

Chuck Morris: Best looking diesel locomotives ever: CB&Q E5, GN SDP45 in Big Sky Blue, ATSF F7 Warbonnet, and BN/BNSF SD70MAC in Cream and Green.
Justin Sandlin: No 40/idle, no locomotive isolation, no TripOptimizer, just coal railroading how god intended it. Outstanding video! [I don't understand these but I presume they are various computer controlled functions.]
