The new Pedemontana Lombarda highway section, with a total route length of 26.2 km (through the territory of the provinces of Como, Monza Brianza and Milan), is divided into 2 functional lots, as defined by CIPE Resolution 97/2009 approving the overall 87-km-long work divided into sections A, B1, B2, C, D, Varese Bypass and Como Bypass.



Track length: 9.6 km of which 9 km to be built
Extension: from interconnection of Lentate sul Seveso with section B1 to Cesano Maderno
Municipalities crossed: Lentate sul Seveso, Barlassina, Seveso, Meda, Cesano Maderno
Route development: redevelopment of the existing former SS35 Milan-Meda expressway. The first section, from Lentate to the Meda curve, has a dual-lane section in each direction with an impassable central reservation, while the next section up to Cesano Maderno consists of a 3-lane section in each direction with an impassable central reservation.

Interconnected works:

  • TRCO06: a direct extension of the former SS35 interconnection branches.


Track length: 16.6 km
Extension: from the interconnection with S.S.35 Milano-Meda in the municipality of Cesano Maderno to the interconnection with Tangenziale Est in the municipality of Usmate-Velate.
Municipalities crossed: Monza Brianza province: Arcore, Biassono, Bovisio, Masciago, Camparada, Cesano Maderno, Desio, Lesmo, Lissone, Macherio, Seregno, Sovico, Vedano al Lambro, Vimercate, Usmate Velate.
Route development: the highway is classified as an Urban Highway characterized, according to Ministerial Decree 05/11/2001, by a design speed range of 80-140 km/h.

Interconnected works:

  • TRMI10: local road system inherent to the Macherio interchange, length 4,781 m
  • TRMI17: local road system inherent to Section C, length 3,511 m


Section B2 extends from the interconnection with the S.P. ex S.S. 35 in Lentate sul Seveso to the interconnection with the S.P. ex S.S. 35 in Cesano Maderno and has a length of about 9.6 km. The B2 is a section in adaptation (redevelopment and upgrading) of the existing road network that falls under the provisions of the Ministerial Decree of 22 April 2004 for the regulation of the adaptation of existing roads. The motorway section, in the section between the municipalities of Lentate sul Seveso and Meda, has two lanes for the most emergency direction. In the section between the municipalities of Meda and Cesano Maderno the section has three lanes per direction. The B2 has a design speed of 120 km/h. There are 4 interchanges (Ex S.S.35 Interconnection, Lentate sul Seveso Junction, Baruccana Junction, Meda Junction).

Section C extends from the interconnection with the S.P. ex S.S. 35 Milano-Meda in the municipality of Cesano Maderno to the interconnection with the Eastern ring road in the municipality of Usmate-Velate. The total development is about 16.6 km (excluding the initial junction). The road site of the main route provides a platform type A “urban highway” with 3 lanes per direction plus emergency, from a design speed range of 80-140 km/h. There are 4 junctions (Junction of Cesano Maderno, Junction of Desio, Junction of Macherio, Interconnection with the ring road East).


The landscaping of above-ground artificial tunnels is based on the assumption that, in the current era of ecological transition, the design of the entire infrastructure should strengthen the link between the physical form of the place and its social, economic and cultural context. In particular, interventions are made on the Seveso tunnel, Barrucanetta tunnel and Arcore tunnels.

1. The Seveso Gallery Rooftop Park presents pedestrian access via aluminum stairs, ensuring accessibility for all users. A ramped path on the northeast side is dedicated to maintenance and rescue. The suspended promenade offers varied spaces with flower meadows, shrubs and trees, with earth movementsto promote biodiversity. The main and secondary earth and gravel paths include equipped rest areas along the way.

2. Through an elevated walkway, the new Barrucanetta Park unites two territories divided by the railway line, expanding the landscape design. The park’s terraces, modeled on the tunnel roof, provide green spaces accessible via a ramped path connecting the different areas. The design recalls that of the nearby Seveso tunnel, ensuring aesthetic and functional coherence to the entire system. The park thus becomes a pivotal element in the harmonization of the urban landscape.

3. The highway section that runs through the municipality of Arcore and its surroundings is immersed in a valuable agricultural-naturalistic environment, part of the Briantei Hills PLIS and a regional ecological corridor. Anthropogenic interventions in this area can compromise the environmental balance and connection between natural habitats. The landscape design aims to mitigate infrastructure impacts by maintaining ecological permeability and recreating natural habitats. Artificial tunnels and vegetation are key strategies to integrate the highway into the landscape, reducing visual and noise impacts and promoting biodiversity.


Free Flow

The Free Flow system, implemented in the new B2 and C sections of the Pedemontana Lombarda Highway, is an innovative toll collection method that eliminates the need to stop vehicles at traditional toll booths. It uses portals that scan and verify vehicle data by laser and On Board Unit (OBU), and through an optical character recognition (OCR) process confirms or corrects the data read by ANPR cameras. The information collected, including OBU data and check results, is then sent to the central system for toll processing.

Dynamic weighing system

The project integrates a dynamic weighing system with FFML portals to detect vehicle weight, using WIM sensors and inductive loops connected to a data logger in the portal cabinet. Peripheral Portal Software creates a license plate-weight association using the obtained data, optimizing costs and installed devices. The central control Software captures and displays the data, enabling export and analysis of relevant statistics.

Structural monitoring

Structural monitoring is essential for assessing the performance of a structure over time, ensuring safety and efficiency. By measuring specific physical parameters at regular intervals, it is possible to follow the evolution of the structure’s condition and develop analytical models to assess changes in its behavior, facilitating timely interventions and efficient maintenance planning. Compliant with the new guidelines and the Smart Road Decree, this approach aims to optimize maintenance and rehabilitation interventions based on objective data, allowing detailed monitoring of the condition of the works and identifying any damage with precision. The proposed monitoring system consists of a wired network of high-quality sensors, including biaxial inclinometers, triaxial accelerometers, and patented sensors to measure the internal tension in concrete without using the constitutive law of the material. These sensors provide real-time information on local tension, facilitating the management and maintenance of structures.


Project implementation with BIM methodology ensures effective communication and optimized simulation of the entire life cycle of the work, with the goal of developing a BIM platform that becomes a “Smart InfraBim-GIS.” Planned activities include modeling of existing conditions, design creation, collision detection, production of graphics, extraction of material quantities, fluid dynamics analysis for fire safety, simulation of construction time, monitoring of construction progress, quality and sustainability management, communication with stakeholders, and creation of a Digital Twin: Smart Infra-GIS Model. These activities aim to ensure an integrated and efficient process for the construction of the work, improving the overall planning, execution and management of the project.
