A20 motorway (Netherlands) Wikipedia
The section near Rotterdam, between the interchanges with the A4 and A16 motorways, is the northern part of the so-called Ring Rotterdam, the beltway around the city.
On a part of this section, the maximum speed is reduced to 80 km/h, which is being enforced by speed cameras calculating the average speed of a vehicle on the stretch between the cameras.
From the first exit, exit 6 (Maasdijk), the European route E25 follows the A20 motorway all the way to its terminus at interchange Gouwe.
Besides, the European route E19 follows the A20 along the 6 kilometers short stretch between interchanges Kleinpolderplein and Terbregseplein, just north of Rotterdam.
The entire route is in South Holland.
