The Great Port Shift: Container Volume on the East vs. West Coast
The landscape of U.S. maritime trade is in a constant state of flux, and recent years have brought significant shifts in where the nation's imports, particularly those arriving from Asia are landing. For decades, the West Coast ports, namely the behemoths of Los Angeles and Long Beach, reigned supreme. However, a combination of infrastructure improvements, global disruptions, and shifting logistics strategies has dramatically altered the balance of container volume, giving the East Coast and Gulf Coast a growing and often dominant share.
Here’s a look at the dynamic forces at play and what it means for the movement of goods in the U.S.

A History of West Coast Dominance
The traditional route for goods arriving from Asia has always favored the West Coast. Ports like the Port of Los Angeles and Port of Long Beach historically handled the vast majority of trans-Pacific trade due to their geographical proximity to key Asian manufacturing hubs. For many years, these two ports alone accounted for approximately 40% of all shipping containers entering the United States.
However, this dominance came with a price: severe congestion. The surge in consumer demand, especially during and after the pandemic, overwhelmed their capacity, leading to months of delays and ships anchored offshore. This created a strong incentive for shippers to seek alternative routes.
The Rise of the East and Gulf Coasts
In a major strategic pivot, shippers began diverting cargo to East and Gulf Coast ports to bypass the congestion and mitigate the risk of labor disruptions that have historically plagued the West Coast. This led to a significant "Great Port Shift," where the East and Gulf Coasts have increased their market share of Asian imports.
Key factors driving this shift include:
• Infrastructure Investment: Ports like the Port of Savannah and the [suspicious link removed] have aggressively invested in deepening channels, raising bridges, and expanding their intermodal rail capacity. Savannah's $220 million Mason Mega Rail facility, for example, has dramatically increased its capacity to move containers inland, making it highly competitive.
• Operational Efficiency: Certain East Coast ports have been shown to rank higher in global port efficiency surveys. While the transit time at sea may be longer, the improved terminal efficiency and reduced vessel backlogs have, at times, made the total end-to-end delivery faster for East Coast destinations.
• Risk Diversification: Labor negotiations and potential disruptions at West Coast ports have caused shippers to diversify their supply chains. This risk mitigation strategy has been a major driver in sending volumes to East and Gulf Coast hubs, like Port Houston, which saw significant volume increases.
Where the Volume Stands Now
The shifting tides have resulted in a significant change in the total volume handled:
• Market Share: For a period, the East and Gulf coasts collectively handled the lion's share of total inbound container volumes, even surpassing the West Coast. While the percentages fluctuate monthly based on factors like holiday peak seasons and tariff front-loading, the trend has been a permanent increase in the East and Gulf Coast's overall market share.
• Top Ports: While Los Angeles and Long Beach remain among the busiest ports in North America, New York/New Jersey and Savannah consistently rank as the top East Coast ports, breaking volume records and cementing their roles as critical gateways.

The Outlook: Flexibility is Key
While the West Coast is making efforts to improve efficiency and recapture volume, the logistics industry has embraced flexibility. The "Great Port Shift" is less about a total replacement and more about a diversification of risk and capacity.
For businesses managing supply chains, the key takeaway is that relying on a single coastal gateway is no longer the optimal strategy. The increasing competitiveness and improved infrastructure of East and Gulf Coast ports provide vital alternatives that can reduce transit times, lower costs, and ensure a more resilient and flexible logistics network.
