SS 36 highway infrastructure and connectivity issues

Concerns have been raised regarding the infrastructure and connectivity of the SS 36 highway in Italy, a strategic route connecting Brianza, Lecco, and Valtellina. Senator Tino Magni submitted a parliamentary inquiry following heavy rainfall that caused flooding between Suello and Civate, highlighting the road’s vulnerability to extreme weather. The inquiry also seeks updates on the Monte Piazzo tunnel design, lane expansions near Lecco, and cycling infrastructure.

Additionally, industrial leaders from Confindustria Lecco and Sondrio have criticized the lack of mobile phone connectivity within the SS 36 and SS 38 tunnels, noting a near-total loss of signal for approximately 40 km between Lecco and Colico.

Following these infrastructure concerns, roadworks have been implemented near Lake Como and the Spluga Pass. In the Monte Piazzo and Somana tunnels, traffic is restricted to a single lane with a 50 km/h speed limit to facilitate construction. Drivers are advised to expect delays and use alternative routes during scheduled closures between Bellano and the Fuentes junction.

Recent reports indicate that these disruptions have become prolonged, with commuters and businesses between Lecco and Colico facing over three years of narrowed lanes and significant congestion. Local citizens have expressed frustration over a perceived lack of visible progress, noting that despite heavy restrictions, there is often minimal activity from workers or machinery during daylight hours. The Monte Piazzo tunnel has been specifically identified as a primary site of frustration. Consequently, there are growing calls for ANAS and regional authorities to provide transparency regarding project timelines, progress, and contract oversight.

New construction projects scheduled for October and November 2026 will introduce further lane reductions and alternating one-way traffic on the SS 36. These upcoming restrictions will affect the stretches between Piona and Bellano, as well as between Dubino and Verceia, impacting travelers heading toward Lecco, Valtellina, and Valchiavenna.
