U.S. Customs and Border Protection (CBP) is running a pilot project at the Sault Ste. Marie International Bridge border crossing between Michigan and Canada.
This port has a unique design that separates commercial traffic from car traffic using an upper and lower plaza. This project is testing whether a two stop sign approach will speed up queuing of autos in the upper plaza. Upon entering the upper plaza, vehicles will be required to stop at the original stop sign. As the vehicle ahead clears, travelers will move to the next (new) stop sign and present their ID to the RFID reader. Once the vehicle at the inspection booth moves on you will proceed forward to the inspection booth.
This project will not affect traffic on the lower plaza. Trucks and vehicles with trailers or campers should use the lower plaza lanes.
LED signage at the plaza will notify motorists of this change and CBP Officers will sometimes direct traffic to help educate travelers on this new process.
