In Switzerland, the Federal Department of the Environment, Transport, Energy and Communications (DETEC) has appointed ETH Zurich to examine and define the Priorities in the implementation of expansion projects national transport infrastructures in consideration, in particular of the impossibility of achieving the planned upgrading of road transport infrastructure and railway. The strengthening of the road network, in fact, is was rejected by a national vote last December in which 52.7% of voters voted against the program of grid improvement provided for by the Federal Decree on the Phase 2023 upgrading of national roads. Development plans of the railway network, on the other hand, present financing problems and implementation and ongoing projects are becoming more costly, with additional burdens which, in the absence of containment of expenses, it is expected to amount to about 14 billion Swiss francs (€14.8 billion).

In view of the prospects for continued growth of the road and rail traffic and the brake on new projects imposed by the vote and rising costs, DETEC has therefore decided to review the projects to assess what are priorities for Switzerland and what should be the made at a later date. The Department has mandated the Politecnico to carry out this examination and to establish priorities, with works that will be supported by advice from a monitoring group and an advisory committee. The results of the Work is expected in the third quarter of this year.
