Context
New disruptions are on the horizon for the thousands of cross-border commuters who travel daily between Italy and Switzerland to reach the Canton of Ticino. Autostrade per l’Italia has announced a series of night closures and intensified daytime construction on the A9 Lainate-Como-Chiasso motorway, a vital route for cross-border commuting. According to a report by Ticinonline, the section between Como Centro and Chiasso, heading north towards Switzerland, will be closed to traffic from 10:00 PM on Tuesday, March 3, to 5:00 AM on Wednesday, March 4. The main reason for this closure is the transit of 'exceptional transport' vehicles, which are so large and heavy that a complete traffic stop is necessary to ensure road safety. Unfortunately, these movements, often unavoidable due to industrial or logistical needs, result in significant delays and detours for those returning to Italy or starting their night or morning shifts in Ticino. For vehicles heading to Switzerland, the mandatory exit will be at the Como Centro junction. From there, the recommended alternative route involves using local roads through the city of Como and heading towards the Chiasso city customs. While this route is relatively short, it is known for heavy congestion, especially during peak hours, and the nighttime highway closure will only exacerbate these issues, increasing travel times. This is not an isolated incident: the same stretch of the motorway was similarly closed from 10:00 PM on Sunday, March 1, to 5:00 AM on Monday, March 2, for 'pavement rehabilitation work' and the installation of a new water drainage system. These interventions are part of a larger maintenance project that will continue over time, effectively turning the A9 into an open-air construction site. Managing such traffic fl...
Operational details
The overall traffic situation between Chiasso and Como is further complicated by the start, as of Monday, of daytime construction work on the Fati viaduct, strategically located before the Monte Quarcino tunnel and the Lago di Como exit. This construction site, described as an 'endless project' by the source, involves pavement rehabilitation and the creation of a new platform water drainage system. The unique aspect of this work lies in traffic management: a lane shift is planned in both directions, meaning that traffic will flow on a single lane in each direction for most of the day. While this setup is necessary for worker safety and the quality of the work, it will significantly impact travel times for the approximately 70,000 cross-border commuters who travel to and from Ticino daily. Autostrade per l'Italia has, however, adopted a dynamic construction site strategy designed to ease congestion during peak hours. Specifically, from 5:00 AM to 10:00 AM in the direction of Switzerland, two traffic lanes will be available. Similarly, from 4:00 PM to 7:00 PM, in the direction of Lainate/Milan, two lanes will also be open. This flexibility, based on traffic flow analysis and estimated travel times, aims to minimize disruptions for commuters. Nonetheless, outside of these priority time slots, the reduction to a single lane will inevitably result in slowdowns and queues, especially on weekdays. The impact is not limited to travel times but extends to costs: longer time spent in traffic means increased fuel consumption and accelerated vehicle wear, factors that can further strain the already tight budgets of cross-border workers. Although Ticino's cantonal and municipal authorities do not have direct jurisdiction over works on Italian territory, they are closely monitoring...
Key points
Faced with this complex traffic situation, cross-border commuters using the A9 must adopt proactive strategies to minimize the impact on their daily routines. The keyword is planning. Before setting out, especially during nights affected by closures or time slots with a single lane, it is crucial to check real-time traffic apps such as Google Maps, Waze, or the Autostrade per l'Italia application. These platforms offer constant updates and can suggest alternative routes in case of excessive queues. Another option to consider, for those living in nearby areas, is to evaluate less congested border crossings, such as Gaggiolo or Ponte Tresa, although these may also experience occasional delays or may not be convenient for all routes. 💡 Practical tips to tackle the disruptions: - Start early: Leaving 15-30 minutes earlier can make a difference, especially for those with strict work schedules. - Carpooling: Organizing with colleagues or friends to share a car reduces the number of vehicles on the road and distributes fuel and toll costs. - Check forecasts: Not only traffic forecasts but also weather forecasts, as bad weather can further worsen the situation. - Patience and caution: Staying calm and adhering to speed limits is crucial for your own safety and that of others. The economic impact of these disruptions should not be underestimated. Increased travel times translate into higher fuel consumption, accelerated vehicle wear, and, for some, potential lateness at work.
