This week's Good Facility is an example of... planning ahead.
This cycle path in the the Dutch town of Elst currently goes nowhere. It's on the edge of a roundabout (the circular path in the foreground). When the roundabout was built, this new path was built at the same time, ready to connect with a new development that is yet to be built. No need for later integration into the roundabout - the path and the junction are already in place.
