Metrobus di Brescia
Italy, Brescia
2005 – 2009

In order to relief the strain on road transportation, the northern Italian town of Brescia planned a fully automatic passenger transport system 13 kilometers in length and with 17 stations. Small transportation units commute at very brief intervals on a two-way basis between the starting point and terminus. Just under six kilometers of the section run underground in the city center. This is where eight stations are planned with four of them having to be built underground.

The Herrenknecht EPB Shield tunnelled its way forward through tuff, silt, clay and gravel from November 2005 onwards. Injections, jet grouting and micropillars were envisaged both for consolidating the ground and securing the weak structure of historical buildings. The project was successfully concluded on the target shaft being reached in February 2009.
