Maastunnel

[1] About 75,000 motor vehicles and a large number of cyclists and pedestrians use the tunnel daily, making the Maastunnel an important part of Rotterdam's road network.

At the end of the Second World War overhead lines were installed to allow for the passage of trolleybuses.

Although two buses were ready for these experimental rides, they were never used for public transportation in Rotterdam, as the overhead lines were removed from the tunnel and used to repair the Rotterdam tramway network overhead lines which had been destroyed during the bombing.

In 1944 the German invaders placed explosives in the tunnel so they could destroy it at a moment's notice.

Above ground, the tunnel's location can be recognized by its characteristic ventilation buildings on both sides of the river.
