Live commercial truck delays at Ambassador Bridge (Windsor–Detroit) (Ontario ↔ Michigan) · updated every 15 minutes from CBP and CBSA · FAST lane available
Current wait: 10 min US-bound · 0 min CA-bound. Data from official CBP (US-bound) and CBSA (CA-bound) feeds, polled about every 15 minutes. North America’s busiest truck bridge — Windsor, ON ↔ Detroit, MI via Huron Church / I-75.
The Ambassador Bridge between Windsor and Detroit is the single busiest commercial truck crossing in North America, carrying a large share of Canada-US merchandise trade and almost the entire just-in-time automotive supply chain. Because so much freight here is scheduled to the hour for Detroit-area assembly plants, waits swing hard with shift changes rather than staying flat through the day. When the bridge backs up, trucks queue along Huron Church Road on the Canadian side and I-75 on the US side, so a delay here ripples well beyond the plaza.
Connecting highways: Highway 3 / Huron Church Road (Windsor, ON) ↔ I-75 (Detroit, MI)
Skip the booth-side scramble. Both CBP and CBSA require electronic advance notification at least one hour before a commercial truck reaches the border.
Most US-Canada commercial crossings follow the same broad pattern: weekdays are heavier than weekends, mid-week is heavier than Monday or Friday, and daytime hours are heavier than overnights. Specific peak windows vary by port, but the table below is a useful planning baseline. Always check the live wait times above before making routing decisions.

| Tue–Thu 10:00–16:00 local | Peak — heaviest commercial volume |
| Fri 14:00–18:00 local | Elevated — weekend repositioning |
| Weekday 22:00–05:00 local | Light — fastest crossings |

Live commercial wait times for the Ambassador Bridge (Windsor–Detroit) are shown at the top of this page for US-bound (CBP) and Canada-bound (CBSA) traffic. BorderPro refreshes the official feeds about every 15 minutes. Peak pressure is usually US-bound mornings tied to Detroit assembly shift changes.
On the Canadian side, trucks reach the Ambassador Bridge via Highway 3 and Huron Church Road in Windsor; on the US side the bridge feeds directly onto I-75 in Detroit. Both approaches are the pinch points that queue first when the crossing is busy.
It depends on time of day and your route. The Ambassador (Windsor-Detroit) is more direct for Detroit-area freight but far busier; the Blue Water Bridge (Sarnia-Port Huron) is the usual alternative when the Ambassador is congested. Check the live wait times for both before committing to a lane.
Commercial truck volumes at most US-Canada crossings peak mid-week (Tuesday through Thursday) during daytime business hours. Monday mornings and Friday afternoons also see elevated delays as carriers reposition for the workweek. Weekends and overnight hours are generally the lightest. Live wait times above reflect actual current conditions, which can deviate from these patterns during holidays, weather events, or inspection surges.
Wait times are published directly by the border agency responsible for each direction of travel: US Customs and Border Protection (CBP) for US-bound commercial traffic and the Canada Border Services Agency (CBSA) for Canada-bound traffic. Values represent the estimated delay between joining the back of the truck queue and reaching the primary inspection booth. BorderPro polls the official feeds every 15 minutes.
US-bound commercial trucks need an ACE eManifest submitted to CBP at least one hour before arrival. Canada-bound trucks need an ACI eManifest submitted to CBSA one hour before arrival. Drivers should also carry the appropriate PARS or PAPS lead sheet, commercial invoice, and any commodity-specific permits.
Yes. Ambassador Bridge has a dedicated FAST (Free and Secure Trade) lane for pre-approved carriers and drivers enrolled in the FAST program. FAST-approved trucks typically experience shorter wait times because their advance trade data is treated as low-risk by both CBP and CBSA. See our FAST card guide for application details.
US-bound shipments use CBP port code 3801. Canada-bound shipments use CBSA FPOA code 0620. These codes are required on eManifest filings and customs documentation — BorderPro fills them in automatically when you select Ambassador Bridge on a manifest.
Wait time data comes directly from the official border agencies and reflects measured queue conditions at the time of the most recent poll. Conditions can change quickly — a single inspection hold can add 30+ minutes within a 15-minute window. Use live wait times as a planning baseline, not a guarantee, and build in buffer for inspections, paperwork holds, and weather.
