In Lyon there has been much talk of a funicular or similar for bicycles, for mounting the fearsome Croix Rousse hill. It was costed at €15M and the idea was abandoned, though I see there is now talk of building a Trampe system as in Trondheim.

However, there is a project being built of a nature you didn't mention : a bicycle tunnel. The same Croix Rousse hill has a road tunnel running under it. A second tube was required, to bring it up to modern security norms; this tube will be dedicated to bicycle, pedestrian and bus traffic. It's to open in 2014.
