ACE eManifest · CBP Port 3802
File US-bound eManifests for Sarnia, ON → Port Huron, MI in under 60 seconds. Preflight validation, live wait-time data, and automated trip numbers.
The Blue Water Bridge is the second-busiest commercial crossing on the northern border and the primary relief valve when the Ambassador Bridge backs up. Two span structures — built in 1938 and 1997 — give it extra commercial lane capacity, and the crossing is particularly important for chemicals, petroleum products, and forest products moving between Sarnia's Chemical Valley and the US Midwest via I-94 and I-69.
File ACE eManifest at least one hour before arrival at Blue Water Bridge using CBP port code 3802. Because Blue Water picks up Ambassador overflow, wait times here can swing quickly — ACE filings that lock in ahead of a surge save meaningful time. Hazmat loads must include the HM-indicator fields; Blue Water's secondary inspection area is equipped for chem inspections.
Weekday peaks run 7-10am US-bound and 3-6pm Canada-bound. Overflow spikes whenever the Ambassador Bridge has a closure or multi-hour delay. Winter lake-effect snow occasionally closes the span temporarily for high winds.
Blue Water is one of the few crossings where commercial and passenger traffic run on completely separated spans — the 1997 twin span is reserved primarily for truck traffic, which removes passenger surges from your wait-time calculation.
Blue Water Bridge is served by brokers concentrated in Sarnia, Point Edward, Port Huron, Marysville, London. BorderPro connects directly to broker RNS feeds so your PARS/PAPS status updates arrive in the same dashboard as your ACE filings.
