Coutts, Alberta to Sweetgrass, Montana is the primary commercial crossing between Alberta and the US, linking Highway 4 to I-15. It is the main gateway for prairie freight — agricultural products, energy equipment, and general merchandise — heading south toward the Great Falls and Salt Lake corridors. Traffic is lighter than the Ontario mega-crossings, so waits are usually modest, but the crossing sits on an exposed prairie stretch where winter weather, not volume, is the most common cause of delay.

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.

Highway 4 on the Coutts, Alberta side connects to I-15 on the Sweetgrass, Montana side. This is the main Alberta-Montana commercial corridor, carrying prairie and energy freight south toward Great Falls and the wider I-15 network.
Because commercial volume is moderate, weather is the more common cause of delay than queue length — the crossing sits on an exposed prairie stretch prone to winter storms and high winds. The live wait times plus a road-conditions check give the fullest picture in winter.
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. Coutts-Sweetgrass 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 3310. Canada-bound shipments use CBSA FPOA code 0407. These codes are required on eManifest filings and customs documentation — BorderPro fills them in automatically when you select Coutts-Sweetgrass 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.
