Well the data for a route via the bridge "Tullbron" looks fine to me. It
definitely looks like it's related to the bridge itself though. If I move
"A" to somewhere in the middle of the short way immediately east of the
bridge (4472673) then it still avoids the bridge. If I place both "A" and
"B" on the bridge it doesn't resolve to a route. Nor if I straddle "A" and
"B" over each end of the bridge. So, my guess is that the bridge isn't in
Cloudmade's underlying routing data for some reason.
