To tackle the Mansholtlaan traffic jams, the final section between Bennekom and the Nijenoord Allee will be widened to two lanes in either direction. In addition, there will be a tunnel ramp at the campus entrance for through traffic. But that tunnel ramp clashes with the campus bus lane, as became clear last week when the plans were presented in the Junushoff.
The problem has to do with the traffic speed on the Mansholtlaan of 80 kilometres per hour. The stipulated tunnel ramp for such a road would only rise back to ground level again after the junction with the bus lane. A shorter tunnel ramp with a steeper slope would be too dangerous while a lower maximum speed would not be appropriate for the road layout, says the provincial authority.
One solution is to move the bus lane at Atlas. Buses would then enter the campus via the roundabout, take an immediate left in front of Atlas and proceed along the existing route. But Wageningen UR is not interested in this option as work is currently underway to create a wetland nature garden in the Atlas grounds. Another alternative is to replace the roundabout with traffic lights, with a tunnel on the south side for cyclists. But this new route would also take up a large part of the nature garden.
Widening Nijenoord Allee will also produce problems. It turns out that there is not enough room for the planned bike tunnels near the Hoevestein and Dijkgraaf student flats.
