This is a good point Eugene, and in fact the bridge names are very good landmarks, given that there are not many other signs on the roads in the Philippines, especially in rural areas. Another thing to take into consideration is that many bridges gain their name from the river they cross over, so there may be many bridges with the same name. They are definitely not tagged consistently at the moment, for example: http://www.openstreetmap.org/#map=17/15.15516/120.59219 http://www.openstreetmap.org/#map=17/15.15840/120.60712 If I remember correctly, they are both named Abacan Bridge, but only one of them has that name on the map, and incidentally the one with a different road name on each side does not.
Do you know if common routing software will pick up the bridge:name=* tag? Yes, I know we're not supposed to tag based on what current software will pick up, but it is interesting to know, given that bridges are such great landmarks. It would be great with a published suggested standard that fits the Philippine conditions. Ronny.
