Major US Ports
Throughput, congestion, and gate-hour changes across LA, Long Beach, Savannah, and Houston.
Overview
Los Angeles and Long Beach (the twin San Pedro Bay gateway) still handle the largest share of US container imports, but Savannah and Houston have absorbed a growing slice of volume as shippers diversify away from West Coast congestion risk — Savannah via strong rail connectivity into the Southeast, Houston via Gulf Coast growth and near-shoring-driven cargo. The four ports move independently: congestion easing at LA/Long Beach doesn't mean Savannah or Houston are seeing the same relief, and vice versa.

Los Angeles / Long Beach
The busiest US container gateway by volume; congestion has shifted in recent cycles from vessel queuing to rail loading and drayage capacity rather than berth availability.
Savannah
Strong inland rail connectivity makes it a common diversion point for Southeast-bound cargo avoiding West Coast congestion, though chassis and drayage constraints still apply.
Houston
Gulf Coast volume has grown alongside near-shoring and Mexico-linked supply chains, making it an increasingly relevant alternative gateway for diversified routing.
Prep Checklist
- ✓Compare current dwell time and rail ramp status across all four ports before committing to a port of entry — vessel congestion alone no longer tells the full story
- ✓If diverting from LA/Long Beach to Savannah or Houston to avoid congestion, check rail and drayage capacity at the destination, not just berth wait times
- ✓Track each port's data independently — easing congestion at one does not predict conditions at the others

They're tracked together because shippers increasingly compare them directly when deciding where to route cargo, and each port's situation is most useful in context against the others rather than in isolation.
