NBI Web Site - Disappearing Structures

[Fred Defender]

Perhaps it is just me, but I thought that I would post here to see if it is...

Are bridges "disappearing" from the National Bridges database? I've noticed this in a number of different areas. The first place that I saw this was I-75 in Sumter County, FL (FIPS code 119). Typing 75 into route number brings up nothing. Using 93 brings up only four structures: CR470 (north and southbound), Coleman Landing, and Panasoffkee Creek. There are a whole bunch of other overpasses that USED to be listed. For example, SR44, southbound Turnpike over NB I-75, CR484, CR472, CR466, CR48, Jumper Creek. There were also a number of culverts south of the I-75/Turnpike interchange that used to be listed but no longer are.

After seeing the news reports from Baton Rouge this weekend, I wanted to see if I could find the I-12 overpass over Airline Highway. I can't be certain (since I've never even been to Louisiana), but I assume that the interchange in question is located in East Baton Rouge Parish. There are no structures listed for I-12 in this parish. I tried US61 and no structures there either.

Has anybody else seen this? Or IS it just me?
