For decades, international containerized freight from Michigan and the broader Midwest has been routed through distant US coastal gateways such as New York, Norfolk and Savannah, or Canadian ports such as Halifax and Montreal. Export-side users have included automotive original equipment manufacturers (OEMs), steel and chemical producers and agricultural shippers, while imports have consisted of tier 1 suppliers, machinery and equipment distributors and retail or e-commerce consolidators.
These routes were not chosen for efficiency or cost. They were imposed by federal restrictions that have for decades prevented containerized freight from entering or exiting the Great Lakes by vessel. US Customs today does not permit such movements through Michigan because no facility in the state meets the required federal standards for security and processing. That is about to change.
In 2026, the Port of Monroe will activate the first SAFE Port Act-compliant international container terminal in the Great Lakes, along with a new roll-on/roll-off (ro/ro) platform that complements existing vessel berths, dual Class I rail access and proximity to interstate highways and Midwest manufacturing. Together, these assets position Monroe as a fully integrated inland gateway for containerized trade and high-value industrial logistics.
Conservatively, 1 million to 2 million TEUs of oceangoing cargo are generated annually from the Great Lakes’ industrial core, according to port estimates. This includes high-value shipments from sectors such as automotive, machinery, chemicals and electronics. Rather than projecting future throughput volumes, the Port of Monroe is focused on establishing a lawful and functioning corridor, allowing the market to respond.
The goal is to restore balance, provide carriers with a practical entry point and give shippers a logistics option that should have existed decades ago. The terminal at Monroe will be available to operators who recognize the value of establishing service in an underserved but strategically positioned market.
The automotive industry, in particular, stands to benefit. With production concentrated in the Midwest and export demand on the rise, direct vessel service from Monroe reduces complexity and supports just-in-time inventory models. Monroe offers a new point of connection between Midwest production and global markets, servings a strategic outlet for general containerized freight and, more uniquely, for the direct shipment of new vehicles via ro/ro or in containers.
Resilience has become a defining priority for today’s logistics networks. The March 2024 collapse of the Francis Scott Key Bridge in Baltimore, a critical ro/ro and vehicle export hub, exposed the system’s fragility. Overnight, cargo flows were disrupted, schedules were delayed and shippers were forced to reroute at significant cost. Inland ports such as the Port of Monroe offer a hedge against that kind of single-point failure.
‘Manageable’ constraints
Do the Great Lakes have constraints? Yes, but they are manageable. The annual three-month winter closure of the St. Lawrence Seaway is predictable and published well in advance, allowing cargo owners and carriers to plan accordingly. Intra-lake shipping continues throughout the winter, particularly with ice-class vessels. Recent climate trends indicate shorter freeze periods and milder conditions, which are gradually increasing intralake shipping capacity during the winter months.
Other northern regions facing even harsher winter conditions have demonstrated what is possible. The Baltic Sea offers a relevant example. Despite a smaller economic footprint and more severe ice conditions, Baltic ports remain active year-round through the use of ice-capable vessels and integrated multimodal infrastructure.
There is no reason the Great Lakes, now that the regulatory path has been cleared, should not do the same and make a comparable contribution to North American trade resilience. Unlike coastal gateways, which face sudden disruptions from hurricanes, labor action and infrastructure failures, the risks on the Great Lakes are stable and foreseeable. That reliability offers a competitive advantage for shippers navigating global volatility.
But infrastructure alone is not enough. What is required is a shift in mindset. Federal freight policy must treat the Great Lakes as a fully integrated corridor. Carriers need to revisit assumptions about vessel size and routing patterns.
Shippers will now be able to prioritize proximity, reliability and carbon performance rather than adhering to legacy paths shaped by outdated restrictions. The introduction of containerized shipping to Michigan presents an opportunity to reinforce the domestic maritime industrial base. Supporting inland container movement by vessel can drive demand for US-built ships, sustain skilled shipyard jobs, and expand the national maritime workforce.
This is not just a logistics upgrade. It is a long-term investment in national capacity, employment, and competitiveness. This is a practical opportunity to enhance the national freight system using inland infrastructure that is efficient, cost-effective and underutilized.
Monroe stands ready to serve shippers, carriers and policymakers seeking flexible, durable solutions. The Great Lakes have always had the potential to support containerized trade. Now that the path is open, the Port of Monroe is prepared to deliver.
