For cross-border workers accustomed to daily commutes via the A8-A9 towards Chiasso, the overnight closure on April 22-23 is an unacceptable disruption. However, Autostrade per l’Italia has provided detailed alternative routes, which require advance planning of departure times to avoid delays. ### Situation before the closure Prior to this scheduled interruption, cross-border commuters could access the A9 directly from Milan via the A8-A9 branch, with a smooth and uninterrupted journey. The closure coincides with the evening rush when many workers leave Switzerland after their shift, creating a reverse traffic flow toward Italy. ### Alternative routes and estimated travel times The two routes recommended by highway authorities require exiting the A8 before the Lainate Arese interchange: Route 1: Via Lainate Arese, Caronno, Garbagnate, Origgio - Exit at Lainate Arese on the A8 Milan-Varese - Continue on SP300 toward Caronno - Turn onto Via Trattati di Roma toward Garbagnate - Merge onto SP233 Varesina toward Caronno/Origgio/Saronno - Re-enter the A9 toward Chiasso at the Origgio interchange - Estimated additional travel time: approximately 15-20 minutes compared to the direct route Route 2: Via Legnano, Uboldo, Saronno - Continue on the A8 Milan-Varese past the Lainate Arese interchange (mandatory) - Exit at Legnano - Follow Viale Marco Polo Ovest - Merge onto SP527 Bustese toward Uboldo/Saronno - Re-enter the A9 toward Chiasso at the Saronno interchange - Estimated additional travel time: approximately 20-25 minutes compared to the direct route ### Implications for cross-border commuters Choosing an alternative route directly impacts arrival times at work. Cross-border workers residing in the provinces of Varese, Como, or Milan must plan an earlier departure to acc...

The overnight closure of the A8-A9 section towards Chiasso requires careful planning to avoid inconvenience for cross-border workers. Here’s a step-by-step guide to handling the change efficiently. ### Step 1: Check the closure times Mark your calendar: from 11:00 PM on Wednesday, April 22, 2026, to 5:00 AM on Thursday, April 23, 2026. Anyone on this stretch of highway after 11:00 PM will be required to follow alternative routes or wait until the reopening. ### Step 2: Select an alternative route Depending on your starting point, choose one of the two suggested itineraries: - From Milan or west: Route via Lainate Arese, Caronno, Garbagnate, Origgio - From east or north of Milan: Route via Legnano, Uboldo, Saronno ### Step 3: Plan an early exit Exit the A8 Milan-Varese highway at the Lainate Arese interchange before 10:45 PM. Passing this point means you must continue on the A8 towards Varese, making it impossible to access the A9 towards Chiasso until the section reopens. ### Step 4: Monitor real-time traffic Before setting off, check traffic updates through: - The free app "Autostrade per l’Italia" - Variable message signs along the highways - The call center at 803.111 - The official websites autostrade.it or RSI ### Step 5: Account for additional travel time Adjust your departure time by at least 30 minutes in your route planner. For example, if you usually leave at 10:00 PM to arrive at work by 11:30 PM, plan to depart at 9:30 PM. ### Step 6: Consider alternatives to private transport If delays are expected to be excessive, consider: - The regional train from Milan to Mendrisio (stopping at Chiasso) - Ticino’s public transport services (TILO) from Varese or Como - The option to work remotely if possible ### What to do in case of unexpected delays If you reali...
