like i said, not everyone is a civil engineer - and clearly not anyone commenting on this thread.
how do you make the bike lane level with BOTH the road and the sidewalk and relatively flat in cross section? With poured concrete, you simply "level" it with a board running from sidewalk to the road surface. Yes, it is not carpenter's level level but how cares? (I watched the contractoor do this on my driveway after he cut out the high ridge my car couldn't clear and did a lower pour. That was just about the width of this path. Now I realize that doing so eliminates all camber and drainage, a point I would have expected from you, the pro.. I don't argue with the approach taken here (assuming there is still enough slope for proper drainage in English weather - I assune they got that right) Why couldn't you simply regrade as they did and pull out the curb and re-pour a new one that slopes from sidewalk to the path surface? (And where the sidewalk and path currently match, nothing needs to be done. Integrating this with wheelchair ramps at intersections shouldn't be too hard. I'm no civil engineer. This is a few minutes of thought. I expect someone for whom this is his life to do better.
