A Metro Ring Project in Copenhagen

 As early as 1986 Erik Reitzel proposed a metro ring, low- price and easy to construct. The metro around the centre of Copenhagen would follow the waterways, i.e. the lakes, the canals, and the sea. This solution would offer many technical and economic advantages compared to a traditionally bored solution.

 

The ring line proposal was ten kilometres long, and ten stations were planned.

 

The project could be built in stages with the possibility of future extension.
