Wilfred Ketelaar has been documenting the progress of work on the route between his home in a village west of Groningen and the city itself.
The first photo shows the previous situation. By the standards of many countries this would be a very good cycling facility. It's separated from the road, and fairly wide. However, it doesn't meet current Dutch guidelines. According to the provincial website this cycle path is narrow and too close to the road.
The first step was to start to prepare the new cycle path foundations alongside the old cycle path.
Note that there is to have a much greater separation from the road as it's positioned completely to the right of the old path, and the new cycle path will be somewhat wider than the old.
Another view of the works a little later when much of the concrete has been poured. The new surface is 3.5 m wide, and extremely smooth concrete. I have the same surface on a path of the same quality on my commute. It's smoother than the road. Smoother than some racing circuits I've been on - like a linear velodrome to your destination.
While works go on, it is necessary for cyclists travelling in this direction to cross the road and use the cycle path on the opposite side.
The speed limit on the road alongside the cycle path is temporarily limited to 50 km/h to avoid dangerous situations when cyclists have to cross.
