Frequently asked
Do I need a passport to cross at Sweetgrass, MT?
Yes. US citizens entering by land need a passport, passport card, enhanced driver's license, or NEXUS card. Non-US citizens need a valid passport plus any required visa or travel authorization.
Are NEXUS lanes always faster?
NEXUS lanes are typically much faster than standard lanes, especially at peak times, but they can still see delays when traffic is heavy or when a few lanes are open. NEXUS lets pre-approved low-risk travelers cross between the US and Canada quickly using dedicated lanes. Apply at ttp.cbp.dhs.gov.
What hours is the Sweetgrass crossing open?
24 hrs/day. Hours are set by CBP and may change for holidays or staffing.
How often is this wait time updated?
CBP officers at each port update their reported wait time roughly every hour while the port is staffed. We re-poll the CBP feed every five minutes and cache the result for both speed and to be kind to the upstream feed.
Why is the wait time blank or "no data"?
CBP doesn't publish a number for that lane right now — usually because the port hasn't reported in over an hour, the lane is closed, or the port is idle. We show whatever CBP publishes without modification.
When is the best time to cross at Sweetgrass, MT?
