Tramway Line 3

New urban connections for Florence
Mobility in Florence is being updated with the 3.1 tramline, which intersects with the Florence-Scandicci line
built by CMB in 2010. It touches one of the most delicate traffic junctions of the city, the Fortezza da Basso: thanks to the project, this area is now taking on a “green” profile.
CMB has responded to the needs of the Municipality of Florence, offering details on building site operations in every phase. It has coordinated the sub-contracting enterprises and mobility stakeholders: from the councillor’s office to the presidents of local districts, from the road cleaning manager to the police. The goal: completing the project in order to reduce the mobility problems of local citizens and visitors.
THE UNDERGROUND UTILITIES
The work was carried out also deep underground, since it also included the movement and updating of all the relative underground utilities, with the involvement of different enterprise.

Technical Description
The route of the 3.1 Line runs inside the city of Florence for around 4.5 km: starting from the current Line 1 terminal, it passes one of the city’s most delicate traffic junctions, Fortezza da Basso, where, to avoid congestion between road and rail traffic, two substantial vehicle underpasses have been planned. With regards to the work of art, given the delicacy of the architectural landscape in the Fortezza area, the insertion of underpasses inside the street network (which was designed by the architect, Poggi, in the second half of the 1800s) has been carefully studied; simulated solutions using traffic models have made it possible to declare the sustainability of the project.
The first underpass, 350 m long and completely covered in Santafiora stone, was constructed in the record time of a year and a half. The double and single tramway is composed of a deep reinforced concrete basin inside of which there is a double slab supporting and blocking the tram track. The surface flooring is mainly composed of natural stone effect self-locking blocks.
“It hasn’t been an easy building site, due to its location in the centre of the city. But we’ve managed to minimize the impact on its citizens”.
