The Canada Border Services Agency has issued a travel advisory for drivers using the Windsor–Detroit Tunnel. Ongoing plaza construction has reduced lane capacity since September 9 and will continue to do so until at least September 19 2026. While real-time postings on September 17 showed “no delay” during off-peak periods, the agency cautions that wait times can spike unpredictably, especially for morning commuters and cross-border couriers. The tunnel is a lifeline for just-in-time automotive supply chains between Ontario and Michigan. Logistics managers are re-routing some freight to the Ambassador Bridge and the new Gordie Howe International Bridge to maintain delivery windows. CBSA reminds commercial operators that alternative crossings may have different NEXUS, FAST or Ready Lane configurations, so drivers should verify eligibility before diverting. Travellers heading to next week’s Detroit Auto Show preview days are advised to build an additional 30–45 minutes into itineraries. Employers with staff who cross daily should revisit flex-work or remote options to mitigate lateness penalties and fatigue. The agency will post hourly updates until construction concludes. The advisory underscores how even short-term infrastructure projects can ripple across North America’s busiest land-border region. Companies with mobility programmes should add dynamic border-wait monitoring to their travel-risk dashboards and pre-trip briefings.
