Ports of Los Angeles & Long Beach
The San Pedro Bay complex is the largest container gateway in the United States and the primary landing point for transpacific imports. What happens on these two adjacent terminals sets the tempo for US inland freight two to three weeks later.

What a disruption here moves
Standing structural relationships, not forecasts. We name the direction and the mechanism, and link the published index where you read the current value — we do not quote a number we cannot cite.
Import surges land as chassis and drayage shortages before they show as vessel queues — the binding constraint is landside, not the water.

Drayage demand in Southern California is highly concentrated, so gate congestion prices into the regional truckload market quickly.

How a problem here propagates
- Import surges land as chassis and drayage shortages before they show as vessel queues — the constraint is usually on the landside, not the water.
- Transload volumes move onto Class I rail within days, so a West Coast surge becomes a Chicago intermodal problem shortly afterwards.
- Labour negotiations, terminal automation disputes and truck-appointment policy changes all move throughput without changing a single vessel schedule.
- When the Panama Canal restricts transits, discretionary cargo shifts here, which is the main way a Central American drought becomes a US domestic trucking story.
