Hi all,
It would be great to get bridge height data into OSM, to stop those
embarrassing truck-vs-bridge-deck interface moments.
It turns out that with the advent of open street-level imagery (e.g.
Mapillary, OpenStreetCam, and of course Geograph) it's really easy to
find and tag bridge heights. I've written a short explanation:

In brief: choose a railway, follow it on OSM, look at imagery for all
the bridges over roads, find a height road sign, read the height from
it, tag the way accordingly.
It's actually pretty fast, and we could get a lot of the UK's low
bridges done easily. I've added a wiki page so that people can note what
they've done:

Anyone fancy joining in?
cheers
Richard
