About this crossing
The Ambassador Bridge opened on 15 November 1929 and carries four lanes of traffic between Windsor, Ontario and Detroit, Michigan. It is privately operated and open 24 hours a day, every day.
It has long been the busiest truck route of the three Detroit–Windsor crossings, so car queues here can be affected by commercial volume in a way they are not at the tunnel. Some of that traffic is expected to shift to the Gordie Howe Bridge over the coming months.
Who can cross here
Cars, buses, motorcycles and commercial trucks — including oversized and wide loads under the operator’s requirements. Motorcycles are permitted here, unlike at the tunnel.
Pedestrians, cyclists and scooters cannot cross the Ambassador Bridge. Foot and bicycle traffic has been prohibited since 11 September 2001. If you are walking or riding, the Gordie Howe Bridge multi-use path is the only crossing between Windsor and Detroit that will take you.
Both NEXUS and FAST operate at this crossing. Select NEXUS above to see the NEXUS lane, and Trucks to see the standard commercial lane. This site does not currently carry a separate FAST reading. CBSA does not report NEXUS times separately for Canada-bound traffic, so that option is unavailable in that direction.
Ready Lane hours
A Ready Lane is a quicker U.S.-bound lane for travellers carrying a card with a chip the booth can read from a distance: an enhanced licence, a U.S. passport card, or a NEXUS, SENTRI, Global Entry or FAST card. An ordinary passport book does not count — its chip cannot be read the same way.
Everyone in the vehicle aged 16 or over needs an eligible card. One passenger carrying only a passport book disqualifies the whole car, so it is worth checking before you commit to the lane.
Lane assignment varies by plaza and by time of day — follow the Ready Lane signage at the booth rather than assuming a particular lane.
As checked on 5 August 2026, CBP advertised one here from 11:00 am to 2:00 pm, Monday to Friday — a narrow midday window on a crossing that runs all day. CBP can change it without notice and this page will not update itself, so confirm on the CBP wait times page if the Ready Lane is why you are choosing this bridge.
Tolls
Cash is accepted here, in either currency — but paying with Canadian cash costs noticeably more, because rates are set in U.S. dollars.
| Car, bus or motorcycle | Rate |
|---|---|
| Premier prepaid card | $5.50 USD |
| Credit card or U.S. cash | $10.00 USD |
| Canadian cash | $14.00 CAD |
| With a trailer | $20.00 USD / $28.00 CAD cash |
Motorcycles and buses pay the same as cars here. Trucks are charged $12.00 USD per axle without an account, or less with an A-PASS. Rates above took effect 1 August 2026 — a reduction made days after the Gordie Howe Bridge opened.
E-ZPass does not work here yet. The operator’s rate card lists it alongside credit cards, but its own footnote says acceptance begins in autumn 2026. Until then, bring a card, U.S. cash, or a Premier card.
This crossing has changed its tolls three times in eight months and is actively competing on price, so treat any figure — including this one — as needing a check: auto toll rates and commercial toll rates.
How to read the times above
“Reported” is when the agency observed the wait. “Feed checked” is when Border Delays last looked for new data — we check every five minutes, but CBP and CBSA publish roughly hourly, so a reading can be accurate and still be up to an hour old.
Agency figures generally measure the inspection queue, not the approach roads. On this crossing in particular, the Windsor approach can add time that the official number does not capture.
