Abstract
The new motorway tunnel under the Ems was created between 1985 and 1989 by the Immersed Tube Method. An account is given below of finished construction, basic geodetic surveys, measurement during construction and examining survey after completion. For the project five tunnel elements prefabricated in a dredged dock, each 127,5m long, had to be set across the Ems and lowered one after the other into position. This necessitated continual, accurate supervision of position, height, and inclination of each tunnel element.
