Open day A4 aquaduct – People looking at the information boards

The A4 motorway from Amsterdam to The Hague has a bottleneck at Leiden, where the road crosses the Old Rhine. The bridge has only 2 x 2 lanes, which causes daily traffic jams. An aquaduct will be made, so that the road can pass under the Rhine. At the same time the road is widened to 2 x 3 lanes and the road will run below ground level, so there will be less nuisance for the people who live next to the motorway.
