Safety projects of the S.S. 34 \u201cdel Lago Maggiore\u201d \"\"\u00a0 Per la versione in Italiano: <\/em>https:\/\/www.stradeeautostrade.it\/ambiente-e-territorio\/la-progettazione-per-la-messa-in-sicurezza-della-s-s-34-del-lago-maggiore\/<\/a><\/p>\n

The State Road 34 (S.S. 34) \u201cdel Lago Maggiore\u201d represents an artery of primary importance of the road system of the Upper Piedmont and of the Province of Verbano Cusio-Ossola. It starts in the town of Gravellona Toce as an offshoot of the State Road 33 \u201cdel Sempione\u201d; it crosses the town of Verbania, and goes back along the shore of Maggiore Lake, crossing the coastal towns of Ghiffa, Oggebbio, Cannero Riviera and Cannobio.<\/p>\n

A little more than 4 km North of the town of Cannobio, the road reaches the border with the Swiss Confederation (Canton Ticino), at the international custom of Piaggio Valmara and continues as Strada Cantonale 13, proceeding towards Locarno and Bellinzona, where it meets the road axis connecting the passes of St. Gotthard and St. Bernardino.<\/p>\n

As a matter of fact, the S.S. 34 “del Lago Maggiore” has an international interest for the high volume of commercial, tourist and cross-border workers traffic; it represents the only infrastructure serving the western shore of the upper Maggiore Lake, since it is not flanked by any other viability practicable by the current traffic volumes.<\/p>\n

From its interruption derive inconveniences and problems not easy to solve that if prolonged in the time can determine important economic damages to the businesses and to the activities of the territory, besides it can negatively affects the international traffic and potentially isolating wide territorial areas of the upper province.<\/p>\n

In the last century, there have been major geological disruptions, including the most important in 1977 that occurred just North of Cannero Riviera, consisting of a landslide of soils and rocks pouring in the main road.<\/p>\n

In the last 17 years the S.S. 34 “del Lago Maggiore”, due to landslides, mudslides and falling rocks, as well as flooding has been closed to traffic at least a dozen times with the consequences mentioned before.<\/p>\n

The most notable events, reported chronologically, are resumed in Figure 2. The territorial authorities, in need to increase the level of safety and wanting to ensure the full usability of the structure, have signed a Program Agreement (D.P.G.R. n. 52 – 09.07.2018), subscribed by the Piedmont Region and the Union of Maggiore Lake (municipalities of Cannobio, Cannero Riviera, Oggebbio and Ghiffa) with the coordination of the municipality of Verbania, having as a general goal the elaboration of surveys, studies and investigation of the geomorphological setting to design and implement all the slope and transit safety projects, excluding some projects carried out directly by ANAS such as the construction of four rockfall protection tunnels.<\/p>\n

Relying on these goals, a first assignment has been given to the Polytechnic of Turin (Department of Engineering of Environment, Territory and Infrastructures Laboratory of Photogrammetry, Geomatics and GIS, Resp. Eng. Andrea Maria Lingua) for the acquisition of spatial data, at high resolution in a complex environment, through the integration of techniques\/instruments as innovative methods with a multi-resolution and multi-scale approach.<\/p>\n

Starting from the results of the general study, the assignments for the technical and economic feasibility studies have been given subdivided into two lots:<\/p>\n
