Anton Constructiewerken produced, conserved and installed temporary port and starboard port beacons for the temporary work harbor on the Afsluitdijk. When a boat arrives, the beacons ensure that the captain of the boat knows exactly what the position of the port is.
The harbor beacons are mounted on signature Levvel blocs. The 6.5-ton Levvel-bloc has been specially developed for strengthening the Afsluitdijk.
