Plenty of Sault families cross the International Bridge to the American Soo — to see relatives, shop, or fill a prescription — and the line decides whether it's a quick errand or a long afternoon. This is the wait to enter the United States right now, as U.S. Customs and Border Protection reports it.
The bridge leaves downtown by Huron Street and Carmen's Way; U.S. Customs is on the far side.
The one bridge across the St. Marys River to the Michigan Soo, open around the clock. These figures are the U.S.-bound line — the wait to enter Canada is not in this feed (see below).

These are CBP's own reported wait times, refreshed about every hour. A lane shown with no delay can still build, and the line can change while you drive — check the official port page before you go.
U.S. Customs and Border Protection reports the line heading south into Michigan. The wait to come back into Canada is handled by the Canada Border Services Agency, which does not publish a live feed for this bridge — the CBSA link below has its own table.
Everyone needs an accepted document to cross. Canadians can use a valid passport, an Ontario enhanced driver's licence, or a NEXUS card; U.S. citizens returning need a passport, passport card, enhanced licence, or NEXUS. Children have different rules — check CBP's "Ready to Cross" guidance below before a first trip.
NEXUS is the pre-approved trusted-traveller lane and usually moves faster, but you need a NEXUS membership to use it, and it isn't staffed around the clock — when it's closed the card still works in the regular lane. The enrolment centre is at the bridge plaza on the Michigan side (900 International Bridge Plaza, 906-632-2631).
The car toll is $6.40 CAD (about $4.60 USD) each way as of April 2026. Through the end of August 2026 the bridge is down to one lane with temporary signals Monday to Thursday for painting and deck repairs, with all lanes open Friday to Sunday — so a weekday crossing can back up beyond whatever the line below says. The bridge authority's page has live cameras and toll details.
CBP refreshes the wait about once an hour, and a short line now can build by the time you arrive — especially weekend afternoons, paydays, and around holidays on both sides.
