Research involving the study of the urban renewal continues, pressing on towards the identification, among all the recently discovered techniques, of new solutions for an appropriate use of urbabized
areas. Prominent among these is the use of the underground, where it is now possible to plan service networks that will leave their maark on vast areas of society in the future.
A precursor of this concept (later propounded by the Cocis) od an underground city organized along systems and non episodes was Gianfranco Magrini (Chairman of the Domani Commission in the Cocis) with his “Tubolario” plan - that is, a new road consisting of a tubolar construction fully submerged in Lake Como at an average depth of 20 metres below the low water level. In a typical part the artery is made up of two cylindrical tubes connected with trusses. Statically, the structure has been scaled in such a way that even with a full load it tends to float, but it is kept submerged by stay rods anchired to ballast resting on the bottom of the lake.
Each of the parallel tubes is subdivided into four chambers: the upper tubes will accomodate the two road lanes; the two lower chambers will carry double-track rails for internationals railway trains of the Underground type adopted in regional areas. | Project for the "Tubolario" for a new road system to be built under lake Como at an average depth of 20 metres below the low water level. |
