VIEW DWT CAMERAS →No Trucks — Large Vehicles Must Use Ambassador or Blue Water Bridges
Per DWTunnel.com, the Detroit-Windsor Tunnel's one-lane-each-direction design and tunnel height restrictions prohibit large trucks and oversized vehicles. Commercial freight and large RVs must use alternate crossings:
- Ambassador Bridge: Primary Detroit-Windsor truck crossing
- Gordie Howe International Bridge (opening 2026): New capacity relief bridge
- Blue Water Bridge: Sarnia-Port Huron alternative for northbound freight
DWT is optimal for passenger vehicles going downtown-to-downtown — faster than bridge backtracking during peak hours.
Pro Tip: Passport + NEXUS for Faster DWT Crossing
US-Canadian border crossings require a valid passport for US and Canadian citizens (or NEXUS card, passport card, or enhanced driver's license for some crossings). DWT typically moves faster than the Ambassador Bridge during commute hours because:
- No commercial truck processing — all vehicles are passenger
- Cashless only — no cash delay at booths
- NEXUS lanes expedite pre-cleared travelers
Monitor CBP border wait times for current processing delays. During major events (concerts, sporting events), DWT fills fast.
