In 2010, all commercial truck traffic was diverted to the new San Luis II Port of Entry 5 miles to the east.

In 2012, two additional inspection lanes were added to the port facility.

In 1952, Mexico built a border station that spanned the entire roadway, leaving only narrow portals for vehicles to pass.

Traffic entering the United States must first travel west parallel to the border before turning right at the port of entry.

This configuration prevents northbound traffic from creating congestion in the middle of San Luis Río Colorado.
