The Public Roads Administration landed in 1992 at a bridge alternative as their preferred solution, backed among others by the Norwegian Haulier’s Association and Hurum Municipality. The former stated that a bridge would result in trucks consuming only half as much fuel on the segment, while the latter was also enacted by the prospect of the bridge becoming a tourist attraction. On the other hand, the bridge was met with protests from environmental organizations and residents of Drøbak and the ministry thus decided to go for a tunnel. A full-scale construction was debated, with two tubes and a new highway all the way to Lier.
