U.S. and Mexico officials are working together to inspect cargo entering into Mexico from the U.S. at the Mariposa Port of Entry in Nogales.
"It is very clear to me this afternoon why Nogales has become the envy of every other port along the U.S. and Mexico border," said Arizona Governor Doug Ducey.
This marks the first time U.S. Customs and Border Protection and Mexican Customs will perform cargo clearance inspections at the same time for the north and southbound traffic.
Officials say this will help reduce wait times and costs for businesses while increasing security.
"When we have Arizona companies that have saved 700,000 plus in the first 30 days of the program that means phase 1 and phase 2 have been incredibly successful. We want to build on that," said Ducey.
Back in August, officials launched the program's first phase.
Joint inspections for cargo coming into the U.S. from Mexico, which has already helped the economy.
Government officials say they have already had huge success from phase 1 and they have already cut wait times to about 20 minutes.
Those 20 minutes are an 85% slash in the previous wait times, cutting costs for importers and transportation companies.
"We have seen our economy growing and we would like it to grow much more quickly. When you have a good trade relationship you have a good relationship at the border," said Ducey.
Officials say they expect to expand the program to the ports at San Luis and Douglas in the future.
