What more can be said. The Dutch care enough about cyclists to sign a diversion when a cycle path is blocked. Before we had seen it, someone having a meal in a restaurant had come over to us and told us the way round the blocked bridge. It was pretty obvious that we could have just cycled down the road to the next bridge across the canal. However, the diversion allowed us to do this through a combination of segregated path as in the photo and quiet back road rather than along the main road.
Heel erg bedankt!
