I went on a bike ride last weekend to map some more cycle routes in Berlin. Route RR8 to Hoppegarten is now mapped apart from a hole in the middle: I lost the route a couple of times. Check on the new cycle map layer (very nice!). On the way back, I was hoping to follow RR7 from Ahrensfelde, but that has not been signed yet, as it seems.

I'm wondering whether it actually makes sense to create the routes as the administration sees them. RR7 and RR8 are "radial routes", which lead from the centre (Schloßplatz) to different points on the perimeter of Berlin. But for a large distance (about 5 to 10 km, I'd guess), they're the same. Having each as its own route relation would mean a lot of extra work to maintain the duplicate part. The other things is that the routes aren't marked as separate routes: The signs just mention various destinations, but no route number. The refs and the distinction between radial and tangential routes is merely administrative.

Supposing you've made it outside Berlin (after some 30 km), it gets really quite nice for biking...
