The Canada Border Services Agency (CBSA) and U.S. Customs and Border Protection have issued joint advisories warning travelers of intermittent lane closures at the Windsor–Detroit Tunnel from September 9-19, with spill-over congestion expected through September 24. Live CBSA data on the morning of September 24 showed wait times fluctuating between 15 and 25 minutes, compared with the usual 5-minute crossing. The tunnel is a vital artery for automotive executives and freight forwarders shuttling between Detroit’s tech-innovation corridor and suppliers in Ontario. Ford Motor Company noted that more than 300 of its engineers make the crossing weekly; the delays have already prompted the firm to hold some hybrid-team meetings virtually. CBSA advises passenger vehicles to consider the Ambassador Bridge during peak hours, but commercial trucks are limited by scheduling slots on the bridge, potentially shifting backups rather than eliminating them. Travelers enrolled in NEXUS or FAST still benefit from dedicated lanes, yet some of those lanes are also affected by construction staging. Employers with cross-border staff should revise travel policies to permit buffer time or remote-work alternatives. The tunnel authority expects full lane capacity to return by winter 2027, but additional weekend closures are likely as crews install new primary-inspection booths.
