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.

Moving a UP/SP/MoPac/H&BV Lift Bridge from Houma, LA to Freeport, TX
Houma, LA was at the end of a 15-mile branch from the Southern Pacific mainline. "Built in 1982 to replace an earlier swing bridge. Abandoned in 1991 and moved to Freeport, TX in 2010" [Houma BH]
(new window) (source) This video uses the modern production style of a bunch of different people saying fluff pieces (of the nature "It was a challenge; but we did it on schedule, within the budget, and with no injuries. I'm proud of the teamwork.") At least during some of the fluff narration, this video shows some interesting images. But some of the video is "talking heads," which drives me nuts watching a person espouse platitudes. It makes me appreciate the 1940s style of a narration by a professional voice explaining what you are looking at.
If I set Google Earth for Jan, 2011 (see below), they catch the span being gone and barges working on dismantling the towers. (I discovered Google Earth allows you to save the viewed image as a file with some high resolution options. But the highest resolution file (4800x2827) just used a lot of disk space to store what was effectively screen resolution. That is, it pixilated real bad when I tried zooming in on the saved image. And I could not find how to get a URL that would reproduce what I was looking at like you can with Google Map or Bing.)

The move was done long enough ago that it is in the Freeport, TX image.
The normal reason for replacing a swing bridge with a lift bridge is to more than double the width of the shipping channel. But upstream from this bridge they have this very narrow passage. I panned between the images so that the image below is at the same scale as the lift-bridge image above. In this case, the swing bridge was replaced because it was worn out.
