I did not realize they had so much information on the bridges, and the ones that have lat longs and NBI identification numbers can be joined to the safety data. Brad is correct on the lat long data being included. I was using a CD they sent in the mail that had it scrubbed, but the online zip file does have lat long data. The problem is the data is terribly inaccurate. When you plot it the bridges are way off. The worst bit is that they are snot systematically off - the result are all over the board - some close some in another state entirely. New Jersey has no lat long data at all and many bridges have the last two digits of detail zeroed out. So, we ended up aggregating everything at the county level since that was the best level of accurate resolution we could get. In the process of up loading those now and will do a blog post on it later today. We are also going to try and extract some geo-coding at the sub-district level if we can pull it off.

It's clunky (it's got fixed-width columns and each row is 432 characters) but it does include lat/long amongst many other attributes.
