The Detroit–Windsor Tunnel runs beneath the Detroit River, connecting downtown Detroit, Michigan with downtown Windsor, Ontario. As an underwater crossing, it is limited to passenger vehicles only and is popular with commuters and business travelers for its direct downtown-to-downtown connection.
Best times to cross: Weekday rush hours (7–9am and 4–7pm) see the heaviest congestion. Midday and weekend mornings are generally faster. Avoid Friday evenings and Sunday afternoons during peak travel periods.
Lane types available: Standard passenger vehicle and NEXUS lanes. No trucks, hazmat, or oversized vehicles permitted in the tunnel.
