The A9 Lainate-Como-Chiasso highway will once again be subject to night closures and daytime construction, significantly impacting cross-border traffic in the coming weeks of March 2026. Autostrade per l’Italia has announced a series of interventions that will require extra attention and planning from the thousands of workers who cross the border daily to reach Ticino. The first closure is scheduled from 10:00 PM on Tuesday, March 3, to 5:00 AM on Wednesday, March 4. During this time, the stretch between Como Centro and Chiasso, heading north (toward Switzerland), will be completely closed to traffic. The stated reason is the 'passage of exceptional transports,' a sporadic event that necessitates utmost caution and a total traffic halt to ensure safety. Drivers needing to travel during these hours will be required to exit at the Como Centro junction and use local roads to reach the Chiasso city customs. This means taking secondary roads, which are already notoriously congested, increasing travel times and...

Dettagli operativi

The impact of these closures and construction on the A9 is not just logistical; it translates into a direct effect on the quality of life and economy of cross-border workers employed in Canton Ticino. Every additional minute spent in traffic means less time with family, less rest, and increased stress. Travel time, already variable depending on peak hours and sudden events, is now becoming even more unpredictable. Just consider that a 30-minute daily delay, multiplied by approximately 220 working days per year, adds up to over 110 hours annually lost in traffic—almost three full work weeks dedicated solely to commuting. The suggested alternative routes, such as local roads after the mandatory exit at Como Centro, are often not equipped to handle the traffic volumes that typically pass through the highway. State and municipal roads leading to smaller border crossings, such as Gaggiolo or Ponte Tresa, while potential escape routes, quickly become congested whenever issues arise on the A9 or A2. This scenario makes trip planning a complex art for cross-border workers, who must constantly monitor real-time traffic conditions, often relying on apps and specific traffic bulletins. The Chiasso customs, already a critical point, will see increased pressure during daytime and evening hours, further compromising smooth traffic flow. From an economic perspective, the increase in travel times also leads to higher costs. Greater fuel consumption, vehicle wear and tear, and, in some cases, the need for unpaid leave or permits due to delays erode purchasing power. For Ticino-based companies, the delays of their cross-border employees can result in reduced productivity or internal organizational issues. It’s a vicious cycle that impacts the competitiveness of the Ticino labor market,...

In light of this situation, the watchword for cross-border workers is organization. Leaving with a small buffer of extra time is no longer enough; adopting a more resilient travel strategy is essential. First and foremost, constantly monitor traffic updates. Apps like Google Maps, Waze, or official bulletins from Autostrade per l’Italia and TCS are indispensable tools. Consider departing earlier on days affected by night closures, especially if your shift starts between 5:00 AM and 7:00 AM, when the impact of highway reopenings is at its peak and local roads are still under pressure. Carpooling is another option that, in addition to reducing costs, can provide moral and practical support in managing delays. ## Practical Tips for Navigating A9 Construction 💡 Plan well in advance: Check traffic bulletins the night before and the morning of your trip. 💡 Flexible hours: If possible, arrange slightly flexible start and end times with your employer on critical days. 💡 Alternative routes: Familiarize yourself with secondary roads leading to the Brogeda, Gaggiolo, and Ponte Tresa crossings. Don’t rely solely on your GPS, which might suggest the fastest route but could also be the most congested in case of unexpected issues. 💡 Car sharing: Consider carpooling with colleagues who take the same route. It reduces stress, costs, and your environmental impact. 💡 Public transport: If your final destination is well-served, consider taking the train or bus for part of the journey, especially during full closures. TILO offers direct connections from Chiasso to major cities in Ticino. These highway disruptions are part of a broader context of challenges for cross-border workers and Canton Ticino, ranging from traffic flow management to the issue of affordable housing, as recently r...
