The Italy-France Intergovernmental Commission for the Southern Alps has approved extended summer operating hours for the Tenda Tunnel in 2026, delivering a significant win for tourism operators and businesses in Piedmont and Liguria who have endured years of economic hardship since the 2020 closure.
Why This Matters
• Peak season access: The tunnel will remain open until 23:00 throughout August 2026, the busiest month for cross-border tourism.
• Economic relief: The move responds to pressure from regional governments and the Italy Ministry of Infrastructure and Transport to support businesses recovering from pandemic-era closures.
• Long-term planning: A six-week total closure starts October 5, giving residents and logistics firms time to arrange alternatives.
• Second tunnel advancing: Financing for the historic tunnel expansion has been confirmed by both countries, with construction tenders expected by year-end.
Expanded Access Throughout Peak Season
The new 2026 schedule represents a careful balancing act between ongoing construction and the urgent needs of an Italy-France border economy that depends on tourist flows and commercial transport. From July 11 through September 13, the tunnel will operate on a tiered system designed to maximize access during weekends and national holidays.
Between July 11 and July 31, weekday access runs from 06:00 to 21:00 Monday through Thursday, extending to 23:00 Friday through Sunday. The schedule accounts for France's Bastille Day celebrations on July 13-14, with extended hours both days to accommodate cross-border festivities that traditionally draw thousands of Italian tourists to the Côte d'Azur.
August 2026 delivers the most significant operational expansion: continuous daily access from 06:00 to 23:00 for all 31 days. This window aligns with Italy's traditional ferragosto holiday period, when coastal Liguria sees its highest visitor numbers and Cuneo Province mountain resorts experience their second-highest occupancy rates after winter ski season.
The first half of September mirrors July's pattern, maintaining extended weekend hours before tapering to restricted weekday access from September 14. During that final phase leading to the October closure, weekday traffic will be limited to three windows: 06:00-08:00, 12:30-13:30, and 18:00-21:00, while weekends preserve the full 06:00-23:00 span.
Impact on Alpine Tourism Corridor
The strategic importance of these extended 2026 hours cannot be overstated for an economic zone that saw tourism revenues decline significantly during the tunnel's prolonged shutdown. The Vermenagna Valley in Piedmont and connected areas in coastal Liguria form a unique transnational market where French and Monegasque tourists account for a substantial portion of summer business.
Recovery Signs from 2025 Season: Early data from 2025—the first full summer since the new tunnel tube opened—showed Limone Piemonte recording a 20-30% increase in visitor numbers compared to the disrupted years. The Liguria region as a whole posted a 6.3% growth in tourist presences, with Imperia Province up 4.47%. Cuneo Province exceeded 1M overnight stays in the first six months of 2025, a 5.3% increase, with mountain destinations like Prato Nevoso surging 25%.
Restaurant owners, ski instructors, and mountain guides in the border valleys received emergency support from the Piedmont regional government during the closure years, underscoring the depth of the economic crisis. The extended summer 2026 schedule is viewed by local chambers of commerce as essential to maintaining this recovery momentum and rebuilding confidence among tour operators.
Construction Timeline and Historic Tunnel Upgrade
The underlying reason for the restricted schedule—and the looming October closure—is the parallel effort to restore the historic tunnel bore to modern standards. Built in the early 20th century, the original tube will undergo a widening and technology upgrade as part of the broader tunnel modernization project.
Anas, the Italian state road company, received formal approval for the detailed engineering plans on July 2 from the Intergovernmental Commission. Tender documents for construction contracts are expected before the end of 2026, with physical work beginning in early 2027. Once complete, the historic tunnel will be upgraded to support the dual-bore system with enhanced fire detection, ventilation controls, and automated incident management capabilities.
The immediate six-week closure beginning October 5 will allow contractors to complete preparatory work on the historic tunnel. Residents and haulage firms have been advised to plan for alternative routes via the Col de Tende road pass, weather permitting, or the longer detour through Ventimiglia on the coast.
Technical Feasibility Study for Two-Way Traffic
Piedmont Region has repeatedly submitted a technical study conducted by the Polytechnic University of Turin to the Intergovernmental Commission, exploring the possibility of allowing bidirectional traffic in the new tunnel during active construction phases. The analysis concludes that such operations are feasible under strict safety protocols, but French authorities have expressed reservations about mixing construction vehicles with civilian traffic in a single bore.
The study has become a political focal point for Piedmont President Alberto Cirio and Regional Transport Councillor Marco Gabusi, who argue that seasonal closures impose unacceptable economic costs on businesses already strained by years of disruption. Their position has garnered support from the Italy Ministry of Infrastructure, which has backed the request for maximum operational flexibility during the summer 2026 season.
What This Means for Residents
For anyone living in or traveling through northwestern Italy, the revised 2026 schedule offers predictability during the critical tourism months but requires careful planning around the October shutdown. Cross-border commuters—including the several hundred Italian workers employed in Monaco and the French Riviera—should note the restricted weekday windows from mid-September onward.
Commercial hauliers transporting perishable goods, particularly the region's renowned Ligurian olive oil and Piedmontese hazelnuts, will need to adjust logistics for the October closure. The Ventimiglia coastal route adds roughly 90 minutes to transit times between Cuneo and Nice, with corresponding fuel and toll costs.
Tourism operators in Limone Piemonte, Vernante, and surrounding alpine villages have the extended August 2026 access they lobbied for, but October bookings will likely suffer. Hotels and mountain refuges are advised to communicate the closure dates clearly in reservation systems to avoid cancellations and negative reviews.
The broader takeaway is that the Tenda Tunnel remains a work in progress, with operational convenience subordinated to long-term infrastructure goals. The dual-bore future promises uninterrupted year-round access, but reaching that endpoint requires enduring periodic disruptions over the next two years. For residents who depend on cross-border mobility—whether for work, commerce, or leisure—the summer 2026 schedule represents a pragmatic compromise between economic necessity and engineering reality.
