Context
From March 16 to 19, 2026, a series of closures are planned on the A9 highway, a vital link between Italy and Canton Ticino, which will affect cross-border commuters, daily travelers, and freight transport heading to Switzerland. The restrictions concern the stretch between Lago di Como, Como Centro, and Chiasso, with night-time hours from 10:00 PM to 5:00 AM the following morning. On Monday, March 16, from 10:00 PM to 5:00 AM on Tuesday, March 17, the section between Lago di Como and Como Centro, heading towards Lainate, will be closed for pavement works. Drivers will be required to exit at the Lago di Como interchange and use ordinary roads to reach Como Centro, where they can re-enter the highway. On Tuesday, March 17, from 10:00 PM to 5:00 AM on Wednesday, March 18, two sections will be closed: from Como Centro to Chiasso towards the Italo-Swiss border, and from Lago di Como to the junction with the A59 Tangenziale di Como heading towards Lainate. These closures are necessary to allow the passage of exceptional transports. The Como Centro interchange will be closed to entry in both directions, with alternative routes recommended to avoid delays. On Wednesday, March 18, from 10:00 PM to 5:00 AM on Thursday, March 19, the Como Centro-Chiasso section will be closed again for pavement works, with the same restrictions at the Como Centro interchange. These night-time interruptions will impact cross-border commuters and workers who daily use this corridor to reach Canton Ticino, especially at the Brogeda and Gaggiolo border crossings, the main points between Italy and Switzerland. Authorities recommend carefully planning travel, considering alternative routes, and allowing for possible delays, especially during morning and evening peak hours. Freight traffic, particul...
Operational details
The A9 closures between Italy and Ticino are regulated by specific ordinances issued to guarantee safety during pavement works and the transit of exceptional transports. Specifically, the stretch between Lago di Como and Como Centro will be affected by works on Monday, March 16 and Tuesday, March 17, while the section between Como Centro and Chiasso will be closed on Tuesday, March 17 and Wednesday, March 18, with an additional closure on Wednesday, March 18 for pavement works. Current regulations impose mandatory exits at the Lago di Como and Como Centro interchanges during closures, with directions for alternative routes via ordinary roads such as the Tangenziale di Como and the SS340. The Como Centro interchange will be closed to entry in both directions, Lainate and Chiasso, during the block phases, thus limiting direct access to the highway. Those coming from the Tangenziale di Como will still be able to use the connecting branch towards the A9. Traffic heading to the Swiss border, especially for cross-border commuters going to Canton Ticino, must exit at Como Centro and follow the ordinary roads to the Chiasso customs. For those heading towards Milan or Lainate, the mandatory exit at Lago di Como means re-entering the A9 at Fino Mornasco, an interchange north of Como Centro. These measures are essential to allow the transit of exceptional transports—vehicles of non-standard size or weight—that require particular space and safety conditions for circulation. The presence of these convoys, crucial for transporting materials and goods important to the regional economy, requires temporary interruptions of ordinary traffic. From a regulatory perspective, these closures are communicated well in advance and accompanied by detailed signage. Italian and Ticino authoriti...
Key points
For Ticino cross-border commuters and workers who daily travel the A9 towards Canton Ticino, careful planning of trips during the week of March 16 to 19, 2026, is essential. The night closures involve mandatory detours, especially at the Lago di Como and Como Centro interchanges, and an increase in traffic on nearby ordinary roads. It is advisable to check closure times and suggested alternatives: those coming from Milan heading to Ticino must exit at Lago di Como and re-enter at Fino Mornasco, while those bound for Switzerland must exit at Como Centro and follow ordinary roads to the Chiasso crossing. These detours can increase travel times by at least 20-30 minutes under normal traffic conditions. Cross-border commuters using the Brogeda or Gaggiolo crossings to enter Ticino should consider this impact, especially during morning and evening peak hours. For those using public transport or carpooling, it is recommended to check with regional transport services for any route or schedule changes. Additionally, Ticino companies and cantonal offices such as the DFE and SECO are encouraged to inform their employees about possible flexible working hours or smart working strategies to reduce traffic load during these days. To monitor and optimize travel, the Frontaliere Ticino website offers a salary calculator and tools for trip planning. It is advisable to regularly consult updates and traffic reports and plan alternative routes where possible. > As reported by ComoZero, the closures are necessary to ensure safety and infrastructure maintenance but require attention and organization from all A9 users, including cross-border commuters.
