Crossing US–Canada bridges on foot is surprisingly reliable.

Very reliable for pedestrians, especially at major crossings like Niagara Falls’ Rainbow Bridge or Detroit’s Ambassador Bridge. Wait times vary by hour and season, but you’ll almost always get through faster than vehicles.

For non-citizens: a valid passport is mandatory (or Nexus card if you’re a frequent crosser). If you’re from a visa-exempt country (like UK, EU, Australia), you just need the passport. Citizens of visa-required countries need a valid US or Canadian visa. Bring proof of ties to your home country if asked. Immigration officers are used to foot traffic and usually breeze you through if your documents are in order.

Just check the specific bridge’s hours – some close to pedestrians late at night or in bad weather. And wear comfortable shoes; it’s a longer walk than it looks.

A pedestrian crossing is almost always the fastest way across, provided you remembered your passport.
