Windsor‑Detroit Tunnel Stays Open Over Grand Prix Weekend – Motorists Urged to Plan Ahead

Yes, the Detroit‑Windsor Tunnel is still open while the city of Detroit hosts its high‑octane Grand Prix this weekend. That’s good news for anyone who needs to cross the border, but it also means you might find yourself stuck in a longer line than usual.

Border officials have confirmed that customs and immigration staff will be on duty throughout the event, and the tunnel’s lanes will stay fully operational. However, with thousands of fans streaming into the Motor City for races, concerts and the usual weekend bustle, traffic volumes are expected to climb.

What does that mean for you? Simply put: expect a bit of a wait, especially during peak hours—think early mornings and late afternoons when the race crowds are heading to and from the circuit. If you’re travelling for work, a quick visit, or just a routine grocery run, consider leaving a little earlier than you normally would.

There are a few practical steps you can take to smooth the experience. First, check real‑time border wait times on the Canada Border Services Agency (CBSA) or the U.S. Customs and Border Protection (CBP) websites, or use a traffic‑monitoring app like Waze. Second, if you have a NEXUS card, use the dedicated lanes—those tend to move faster even when the overall flow is slower.

Some drivers also opt for the Ambassador Bridge as an alternate crossing, but that route can experience its own bottlenecks, especially with event‑related traffic diversions. So weigh your options, perhaps even map out a backup route before you set out.

Lastly, keep an eye on any announcements from local officials. Should an unexpected security measure or a sudden surge of fans cause a temporary closure, they’ll post updates on the City of Windsor and Detroit city‑government websites as well as local news stations.

Bottom line: the tunnel’s open, but the weekend’s excitement could translate into longer travel times. A bit of planning—checking wait times, leaving early, and maybe having a plan B—can make the difference between a smooth crossing and a frustrating jam.
