WASHINGTON — Nearly three years after the beginning of the COVID-19 pandemic, global supply chains and international ocean carriers have seen cargo volumes return to pre-pandemic levels.

Arizona’s governor has allocated $8.9 million to help modernize the port of entry in Douglas, where a new commercial one is being built to bolster the state’s trade with Mexico.

The discomfort of drivers having to wait long hours to enter Texas from Mexico should be considered amid the focus on freight delays resulting from Gov. Greg Abbott’s recent directive to enhance border safety inspections, says the head of the Texas Trucking Association.

The head of one of Canada’s largest supermarket chains says the vaccine mandate for truckers crossing the U.S.-Canada border is raising the cost of shipping fresh food. But so far, it has had little impact on the retailer’s ability to stock shelves.

Starting Jan. 22, travelers entering the United States at land ports of entry — notably along the Canadian and Mexican borders — and ferry points who are not U.S. citizens must be fully vaccinated against COVID-19, the Department of Homeland Security announced.

As of Jan. 15 new, tougher COVID-19 vaccine requirements took place for people to cross from the U.S. into Canada. That applies to truck drivers and other essential workers.

More stringent COVID-19 vaccine requirements set to take effect at the borders may put new pressure on freight traffic between the United States and Canada, experts said.

Government leaders in Ontario and Michigan have partnered to advance transportation and mobility technologies in a cross-border testing setting.

Truck crossings between the states of Michigan and New York and the province of Ontario were fairly steady last year, declining just .42% versus 2016 levels, according to a report from the Bridge and Tunnel Operators Association.
