Pedemontana Lombarda Highway - Sections B2 and C

The Pedemontana Lombarda Highway project foresees the executive design and construction of a smart road for approximately 26 km of highway and connected road mobility. The section includes Section B2 (approximately 9 km), from Lentate sul Seveso to Cesano Maderno, and Section C (approximately 16 km), from Cesano Maderno to the East Ring Road A51. The activities include the connected works concerning fixing sections of local roads near the highway. Both sections include trenches, embankments, tunnels and viaducts, ensuring efficient and modern road connectivity. 

Approximately 85% of the route of the two sections is located underground, to minimize the environmental impact and for the difficulty of crossing one of Europe's mostly built areas. Section B2 will mainly develop within an artificial tunnel and trench (approximately 6.5 km on a total of 9km), while section C will be made by approximately 15 km of artificial tunnels and trenches, besides short sections on embankments and viaducts.

The project was commissioned by Autostrada Pedemontana Lomabrda S.p.A, with concessionary Concessioni Autostradale Lombarde S.p.A. It is part of the greater "Sistema Viabilistico Pedemontano", a work of national interest that is strategic for the new large road mobility structure and for the economic and territorial devlopment of Lombardy and the North of Italy. 

Sustainability and innovation: technologies for driverless vehicles and structural diagnostics

The project will be strategically valuable for the territory. The project's main purpose is to reorganize the road connections of the Varese-Como-Bergamo-Milan quadrant, decongesting the traffic on the A4 and the urban centres it passes through, while relieving that of the Milan Ring Road system (Milan's Tangenziale), with the creation of a new axis outside the metropolis. 

The new routes will be true "smart roads," which will also be innovative even in anticipation of future maintenance activities. The design solution developed by Webuild includes the installation of cooperative intelligent transportation systems (C-ITS), the use of technologies that will make the roads ready to accommodate even self-driving vehicles, and the installation of a continuous diagnostic system of the main load-bearing structures through tools for monitoring the main structural stress parameters (deformations, loads, vibrations, temperature). 

In particular, the sections will be equipped with innovative features: i.e. alert system for accidents, road works, obstacles on the carriageway and vehicles heading in the wrong direction, the dynamic management of road lanes, the transmission of speed limits and other driving information to onboard dashboards; and the collection of traffic data.

As a preparatory activity, the project also foresees the reclamation of the areas that were subject to the 1976 environmental disaster in Seveso.
