In the East of Assen there is an underpass which dates to the 1960s which goes under the railway track and a road. There are several underpasses in the city for cyclists and pedestrians - this is the only one which accommodates cars as well.
The cycle paths are narrow by modern standards at only 2.5 m wide for a bidirectional path, but other features of this underpass are rather good.
- It separates cyclists from pedestrians as well as from motor vehicles.
- The tunnel goes deeper for motor vehicles than for cyclists because motor vehicles (e.g. trucks) can be taller than bikes. This means that cyclists don't have to go so deep and so the gradient to climb at the other side is easier.
- The path is bidirectional on both sides of the road, meaning that for a lot of journeys cyclists don't need to cross the road at all.
