Description

The original crossing of RW A4 with the Oude Rijn river at Leiderdorp consisted of a bascule bridge. When the bridge was opened for shipping, traffic was blocked to such an extent that long queues developed.

To improve traffic flow over the A4, it was decided to widen it from 2x2 to 2x3 lanes and to build an aqueduct at the Oude Rijn junction. The deepening of the A4, incorporating the aqueduct, at the Leiden and Leiderdorp sites will also improve the integration of the A4 into the landscape and remove the barrier between the areas.

PLEASE NOTE: Unfortunately, only 20 places are available!

Reception of participants from: 13.00
Start of excursion programme: 13.30
End of excursion programme: 16.00

Participants are expected in the above-mentioned Information Centre from 13.00, where a cup of coffee or tea can be enjoyed. This will be followed by a presentation on the widening of the RW A4 in general and the construction of the Oude Rijn Aqueduct in particular.

Afterwards, a walk will be made along the work at Oude Rijn Heights.
