For a few years now, every road construction project near my Amsterdam home has removed car lanes. Also parking. Usually the freed space goes to protected cycle paths, but sidewalks, trees, and playgrounds sometimes win some new space as well.
(N.b. there is a plan to add a lane to portions of the outer ring highway, so "more car lanes to reduce traffic" still has some advocates.)
