The Canada Border Services Agency (CBSA) updated its official Border Wait Times portal on 27 September 2026 to flag continuing lane reductions at the Windsor-Detroit Tunnel, a key artery for cross-border commuters and auto-industry executives shuttling between Michigan and Ontario. As of 13:23 EDT, both commercial and passenger vehicles faced 15-minute queues—short by Los Angeles standards but unusually long for a tunnel that normally clears cars in under five minutes. The work, slated to run through 19 September, involves resurfacing the Canadian plaza and upgrading radiation-detection portals. Combined with periodic closures tied to Detroit waterfront events, mobility advisers say the disruptions can easily stretch to 30 minutes during morning and evening peaks. For U.S. companies running just-in-time parts deliveries to assembly plants in Windsor, even modest delays can trigger production slowdowns. Logistics managers are diverting some traffic to the Ambassador Bridge or the new Gordie Howe International Bridge, which reported “no delay” and 10-minute crossings respectively in CBSA’s latest update. Cross-border business travellers are advised to enrol in NEXUS or use the Ready Lane, though the latter is available only midday on weekdays. Travellers should also carry printed meeting invitations; anecdotal reports indicate secondary inspections have increased as officers juggle construction-related traffic flows. CBSA’s page, refreshed every hour, will continue to provide live updates. Companies with rotational assignees living on one side of the river and working on the other may want to revisit flexible-start policies until the tunnel re-opens fully.
