TRANSPORT GEOGRAPHY OF NORTH AMERICA: ROAD, RAIL, AND
MARITIME NETWORKS

Abstract:
North America's transport geography is defined by a vast, integrated network of
highways, railways, and maritime routes that form the backbone of the continent's economic
connectivity. This article explores the structure, spatial distribution, and functional
interrelationships of these transport systems across the United States, Canada, and Mexico. The
study highlights the strategic importance of major corridors, trade flows under the USMCA
agreement, and the role of ports and inland hubs in continental logistics. It also examines
contemporary challenges such as infrastructure aging, congestion, and climate vulnerability.
Keywords:
Transport geography, North America, highway systems, rail freight, seaports,
intermodal logistics, USMCA, NAFTA corridor
Transport networks are vital to the economic integration and spatial development of the
North American continent. Comprising the United States, Canada, and Mexico, North America
hosts one of the world's most sophisticated and extensive transport infrastructures.
Historically shaped by westward expansion, industrialization, and trade liberalization
(notably NAFTA and now USMCA), the continent’s road, rail, and maritime networks have
evolved into interconnected corridors supporting billions of dollars in goods movement
annually.
This paper examines the geographic structure and dynamics of the three main transport
modes—
automobile (highways), railway
, and
maritime shipping
—in the North American
context. It also discusses recent shifts driven by economic globalization, digitalization, and
environmental pressures.
This study employs a multi-scalar approach that includes:
GIS mapping and spatial analysis
of transport corridors and logistics hubs;
Review of government transport data
from U.S. Department of Transportation (USDOT),
Transport Canada, and Mexico’s Secretaría de Comunicaciones y Transportes;
Comparative case studies
of key systems: the Interstate Highway System, Class I freight
railroads, and major seaports such as Los Angeles, Houston, and Vancouver;
Literature review
on regional transport planning and trade logistics under the USMCA
framework.

Road Transport System (Highways)
The
United States Interstate Highway System
, initiated in the 1950s, spans over
78,000 km
, linking major metropolitan areas, border crossings, and industrial centers.
Canada's Trans-Canada Highway
is the world’s second-longest national highway
system, stretching over 7,800 km from British Columbia to Newfoundland.
Mexico’s Federal Highway Network
, including toll-based "autopistas," connects
northern maquiladora zones to central markets and ports.
Key Road Corridors:
I-35 Corridor
: From Laredo (Mexico–US border) to Minnesota, crucial for USMCA
trade.
Pan-American Highway
: Links Canada, the U.S., and Mexico, extending into Central
America.
Rail Transport System
North America’s rail network is freight-dominated. The U.S. alone operates over
225,000 km
of rail lines.
Class I Railroads
(e.g., Union Pacific, BNSF, Canadian National, Canadian Pacific
Kansas City, Ferromex) manage continental-scale operations.
Intermodal rail terminals
(e.g., Chicago, Kansas City, Toronto, Monterrey) serve as
vital links between seaports and inland destinations.
Notable Developments:
The 2023
CPKC merger
(Canadian Pacific + Kansas City Southern) established the
first rail network linking Canada, the U.S., and Mexico under a single operator.
Maritime Transport System
Major seaports
:
o
U.S.
: Los Angeles, Long Beach, New York/New Jersey, Houston
o
Canada
: Vancouver, Montreal, Prince Rupert
o
Mexico
: Manzanillo, Veracruz, Lázaro Cárdenas
These ports handle containerized and bulk cargo, forming gateways for trans-Pacific and
trans-Atlantic trade.
Great Lakes–St. Lawrence Seaway
enables inland navigation between the Atlantic
Ocean and central North America.
North America's transport geography reflects both
natural constraints
(e.g., mountains,
coasts, rivers) and
economic imperatives
(e.g., trade, urbanization). The integrated tri-national
network under USMCA has allowed:

Efficient supply chain integration
, especially in automotive, electronics, and
agriculture sectors;
Growth of
inland logistics hubs
like Chicago, Dallas, and Guadalajara;
Expansion of
multimodal freight systems
using rail-truck-port connectivity.
Challenges:
Infrastructure aging
: Many roads and bridges require major rehabilitation;
Congestion
: Urban bottlenecks and port delays impact delivery times;
Environmental vulnerability
: Hurricanes, wildfires, and heatwaves affect transport
continuity;
Carbon emissions
: Transport is a major GHG contributor, prompting investment in
electrification and sustainable mobility.
Technological Innovations:
Smart logistics (IoT, AI) and automation (self-driving trucks, automated ports);
Electrification of freight corridors and promotion of rail-to-truck modal shifts.
North America's road, rail, and maritime transport systems form an intricate, high-
capacity network critical for continental and global trade. Their effectiveness is shaped by
geographic patterns, economic linkages, and political cooperation across borders.
Recommendations:
Invest in
infrastructure modernization
with a focus on climate resilience;
Promote
intermodal transport
to enhance efficiency and reduce emissions;
Support
regional coordination
in planning and policy under USMCA frameworks;
Accelerate adoption of
smart and green technologies
across all transport modes.
A robust, adaptable, and sustainable transport geography will be key to North America’s
future competitiveness and environmental responsibility.
