A huge multidirectional multidimensional intersection in Hertogenbosch, Netherlands, was built in 1965 when city planners thought cycling was dead, and the car would rule. The intersection was extremely complex, and wasted a lot of space.
It had been built at one end of an island, and had to serve traffic flows from/through several directions at once. While the design worked reasonably well for car drivers, some of the flows they used were …strange… and in any case cyclists and pedestrians had to take circuitous routes.
The intersection was redesigned/rebuilt in 2014 to give plenty of cycling routes, simplify the life of car drivers, and a bunch of open space was created from what had been streets.
