A transformer does not fit in a container, does not fit through a Baltimore tunnel, and does not wait well on a wharf. Project cargo is a sequence of hand-offs, and each one is a place to lose a week: the crane that is not booked, the permit that names the wrong route, the laydown yard that is full. Baltimore 3PL runs that sequence from one desk. Stevedore, rigger, heavy-haul carrier and site crew work from one plan with one set of dates.
Dundalk Marine Terminal is the breakbulk and ro-ro terminal at the Port of Baltimore. It has 570 acres, 13 berths, mobile heavy-lift cranes rated to 550 short tons, covered sheds and Norfolk Southern rail on the terminal with a heavy rail spur. Locust Point handles breakbulk and general cargo. Private terminals around the harbor handle steel, bulk and project pieces. The port is the No. 1 US gateway for ro-ro farm and construction machinery and No. 2 for imported aluminum.
How it runs at the Port of Baltimore
The plan starts with your drawings: weight, center of gravity, dimensions, lifting points. From that we build the move.
- Discharge. The stevedore lifts the piece at Dundalk or Locust Point. Heavy pieces go straight to a multi-axle trailer. Lighter pieces go to the shed or a laydown area.
- Laydown. Partner yards in Dundalk, Sparrows Point and Curtis Bay hold pieces until the site is ready. Yard storage bills per day and costs less than terminal storage.
- Route. Loads over 14 feet 6 inches high or 11 feet wide cannot use the I-95 Fort McHenry Tunnel or the I-895 Harbor Tunnel. They loop the west side of I-695. We survey the route, pull the permits and book the escorts.
- Delivery. The heavy-haul carrier delivers to site, and a rigging partner sets the piece on its pad if the scope calls for it.
Customs clearance is coordinated through our licensed customs broker partners. Daily status by email lists each piece by tag number, location and next move.
Breakbulk that moves like freight
Not every project is a single heavy piece. Steel coils, pipe, crated machinery parts and bundles of lumber discharge as breakbulk and move by flatbed, step-deck or rail. The ro-ro logistics page covers machines on wheels. This page covers everything that needs a crane.
What the partner network brings
Baltimore 3PL does not own a crane, a trailer or a yard. We coordinate rigging partners, heavy-haul carriers, laydown operators and terminal stevedores from a network we have curated for 50 years, and we stay accountable for the result. One desk, every building. The desk gets the right partner for the lift.
Project cargo rewards that model. A 200-ton transformer needs a different rigger than a 20-ton switchgear lineup. A pressure vessel going to a plant needs a route survey. A shipment of generator sets for a data center campus needs a partner with a yard and a schedule that matches the construction crew. We place freight only with partners whose permits and equipment fit the piece. One phone number, (419) 745-9492, reaches the desk Monday to Friday, 07:00 to 18:00 Eastern, after hours by arrangement when a vessel schedule demands it.
What it costs and what moves the price
Project cargo is quoted per piece or per shipment with a line for each hand-off: terminal handling, laydown, rigging, heavy-haul, permits and escorts. The price moves with:
- Weight and dimensions. These set the trailer, the axle count, the crane and the permit class.
- Route. The tunnel detour adds 30 to 35 miles and 45 to 60 minutes per leg, plus escort time.
- Permits and escorts. Each state on the route issues its own permits and sets its own escort rules.
- Laydown days. Pieces that wait for the site bill per day.
- Site work. Setting on a pad, unloading with a site crane or a rigger adds a line.
- Schedule. A fixed outage window or a vessel cut-off that cannot move costs more than a flexible date.
The demand around the port
Three programs are shaping project cargo in the region. The Anduril submarine-component shipyard at Tradepoint Atlantic, announced October 6, 2026 at $3.7 billion with about 3,100 direct jobs, brings years of inbound steel, modules and machine tools to Sparrows Point. The Sparrows Point Container Terminal, under construction next door, is a $1.2 billion build with its first berth in 2028. Data center campuses, Quantum Frederick on I-70 and Loudoun County, Virginia on the far side of the Beltway, take generators, switchgear, chillers and transformers through the port and out along I-70 and I-95.
Each of those lanes crosses or skirts the harbor. The Key Bridge rebuild opens in late 2030. Until then the over-dimensional route from the east side terminals to Northern Virginia is the I-695 west loop. The Key Bridge routing playbook lays out the limits, and the data centers page covers the Frederick and Loudoun lanes.

Questions shippers ask
01Which Baltimore terminals handle breakbulk?
Dundalk Marine Terminal has heavy-lift mobile cranes and covered sheds. Locust Point handles breakbulk and general cargo. Private terminals on the harbor handle bulk, steel and project pieces.
02Can you move a transformer to a data center in Loudoun County?
Yes. The piece discharges at Dundalk, a rigging partner loads it to a multi-axle trailer, and the route runs the west side of I-695 and on toward Northern Virginia with permits and escorts.
03Do you own cranes or heavy-haul trailers?
No. We coordinate rigging partners, heavy-haul carriers and terminal stevedores from a network we have curated for 50 years, and we stay accountable for the result.
04Can project pieces wait near the port?
Yes. Partner laydown yards in Dundalk, Sparrows Point and Curtis Bay hold pieces until the site is ready for them.
05What about hazmat project cargo like battery containers?
Containerized lithium-ion storage units are Class 9 hazmat and cannot use the harbor tunnels. We route them around the tunnels with partners who hold the endorsements.
