Would it be useful to import data from the US FHWA National Bridge Inventory? They have data on every single bridge in the US.

Some of the data attributes line up with current bridge properties, while other data points would create new properties. Data can be found at http://www.fhwa.dot.gov/bridge/nbi/ascii.cfm

The data has the following data attributes:

State Code

Structure Number

Inventory Route

Record Type

Route Signing Prefix

Designated Level of Service

Route Number

Directional Suffix

Highway Agency District

County (Parish) Code

Please read http://wiki.openstreetmap.org/wiki/Import/Guidelines first, further there is a US specific import list https://lists.openstreetmap.org/listinfo/imports-us that should be adressed too.

To the data itself, some of it would seem to be useful for OSM (for example clearance) and a lot not. As so often is such cases the best use woud likely be as reference material for QA.

Not a small or easy task! Only a small subset of those fields would even possibly belong in OSM, you'd have to make sure you used the right OSM tags for them, and you'd have to be very careful to match NBI data with the correct OSM bridge features, if they exist. To add to the complexity, there's not only bridge=* tags, but also the man_made=bridge tagging scheme, and bridge relations. Could be a good MapRoulette task, but I'd recommend you start with the talk-us mailing list, and see if anyone's been working on it already. For example, @mvexel wrote this blogpost about US bridges a few years ago.

Ryan_C yes its great to do so. -ask the local community first since theres a lot of extra work if theres a green light. -handsome are clearances but the list is hugh so there has to be a selection to decide what should ? -the Wiki about bridges is not this big, so that should be corrected as well, before you import it.
