Mapnik has a problem rendering an intersection on a bridge. It draws two bridges, where one arbitrary path seemingly spans the other.

See for example http://www.openstreetmap.org/?lat=49.542075&lon=8.661282&zoom=18 which tries to render three ramps meeting at an overhead cycle path.

Will have to look at that. Looks at first sight to be a mapnik quirk

Here's another example, but with roads. There are three places on this map with bridges forking/merging:

While the original cycleway bridge example still has to be done, the other example (in Boston) is quite ok these days, right?
