Lonato del Garda tunnels

One of the most interesting tunneling projects in Italy

Designed by Pini Group for the General Contractor Cepav Due.

The Lonato del Garda tunnel is part of the Milan-Verona high speed railway line; it consists in two single track tunnels having a length of 4.75 km. The tunnels will be excavated by means of an 10 m diameter EPB machine.

The particularity of the project is represented by the complex geological context. The region of the Garda Morainic Amphitheatre is characterized by glacial and fluvio-glacial deposits and by a hydrogeological structure consisting in several deep and surficial aquifers. A further challenge for the design team, leaded by Davide Merlini and Maurizio Tanzini, was represented by the underpassing at low overburden of the A4 Milan - Venice highway and other major buildings and surface structures.

The project also includes the construction of two additional major tunnels – so-called Calcinato II and San Giorgio in Salici. They will be excavated by means of conventional method and include cut and cover portions.
