When you run intermodal in Maryland, you are running Baltimore. It is a heavy-duty, blue-collar port city that doesn't forgive rookie mistakes. For an owner-operator in 2026, the Maryland market is defined by tight urban clearances, massive roll-on/roll-off (RoRo) volume, and the lingering, brutal traffic realities left behind by the I-695 Key Bridge collapse.

If you don't know your tunnel restrictions and local bypasses, Baltimore will eat your clock and your fuel before you even hit the terminal gate.

The Maryland Terminal Directory

Unlike the sprawling, multi-city port networks of other East Coast states, Maryland's heavy freight is highly concentrated. You are either battling the chassis lines at the ocean terminals right on the water, or fighting the local city traffic to bump the rail yards just a few blocks inland.

Zone A: The Ocean Ports (Broening Highway)

If you are pulling ocean freight in Maryland, you are getting intimately familiar with Broening Highway. This single corridor handles a staggering amount of the East Coast's container and automotive volume.

Seagirt Marine Terminal (2600 Broening Highway, Baltimore, MD 21224) is the container heavyweight of the region. This yard runs deep and fast, but the chassis pool lines can back up straight onto the street during peak discharge. Have your TWIC card ready and your appointment window verified, or port police will bounce you out of the queue.

Right next door is Dundalk Marine Terminal (2700 Broening Highway, Dundalk, MD 21222). Dundalk handles containers, but it is famous for being one of the largest RoRo (Roll-on/Roll-off) and breakbulk facilities in the country. If you pull flatbeds, step-decks, or heavy agriculture/construction equipment, this is your home base. Be prepared for aggressive, oversized escorts and tight turning radiuses inside the gates.

Zone B: The Rail Anchors (East Baltimore)

Just inland from the water, the rail yards keep the domestic and transloaded freight moving west toward the Ohio Valley. Accessing these yards means you are no longer on the main interstate; you are fighting tight local streets and aggressive city drivers.

CSX - Keith Avenue (4801 Keith Avenue, Baltimore, MD 21224) sits right in the shadow of the marine terminals. It is a compact, high-velocity yard. The turn times can be fast, but the immediate approach requires navigating a heavily industrialized zone packed with other owner-operators fighting for space.

A few blocks north, NS - Bayview (4800 E. Lombard Street, Baltimore, MD 21224) serves as Norfolk Southern's primary Baltimore anchor. Pulling a 53-foot box out of here means merging directly into the absolute chaos of East Lombard Street. Watch your mirrors constantly; local four-wheelers will dart around your blind spots while you try to swing wide for your turns.

The MD Dispatch Playbook: Tunnels, Tolls, and Traffic

In the Maryland market, your biggest enemies aren't just the chassis lines, they are the infrastructure and the state police. The Baltimore port complex forces you into some of the tightest, most heavily monitored corridors on the East Coast. If you don't map out your Hazmat routing and anticipate the heavy scale-house presence on I-95, the state will bleed your margins dry before you even bump the dock.

The Hazmat Tunnel Trap 

This is the single biggest trap for out-of-state drivers. Because of the ongoing routing shifts from the I-695 Key Bridge loss, you must know the tunnel laws. Vehicles carrying hazardous materials (including many battery loads) are strictly prohibited from using the I-95 Fort McHenry Tunnel and the I-895 Harbor Tunnel. If you are placarded, you must take the long way around the western loop of I-695. Get caught in the tunnel approach with hazmat, and the Maryland Transportation Authority will hit you with massive fines and points on your CDL.

The Broening Highway Bottleneck 

With Seagirt and Dundalk sitting right next to each other, Broening Highway is a constant choke point. Do not rely on your GPS ETA when heading into this zone. Shift changes, rail crossings, and sudden terminal congestion can turn a 5-mile drive from I-95 into a 45-minute parking lot.

The Mid-Atlantic Weigh Stations 

Maryland State Police are notoriously strict on the I-95 corridor heading north toward Delaware and south toward D.C. Make sure your tandems are slid legally, your lights are perfect, and your overweight permits for Dundalk loads are sitting right on your dash.

Brawling in Baltimore

The Maryland intermodal market is a highly concentrated, high-stakes environment. You aren't running hundreds of empty highway miles; you are fighting in the trenches of Baltimore's industrial sector. Between the intense traffic of Broening Highway, the strict tunnel restrictions for hazmat, and the tight city approaches to the rail yards, this state demands a driver who pays absolute attention to the details.

But if you know how to navigate the I-695 detours, keep your paperwork flawless, and manage the tight urban clearances, Baltimore is an incredibly lucrative market. Master the Broening Highway hustle, and you'll keep your truck loaded and profitable all week long.
