From a PierPass news release:

In the wake of a tentative labor deal announced Feb. 20 and the formation of a port-wide chassis pool on March 1, marine terminals at the Port of Los Angeles and Port of Long Beach moved 46% more cargo containers by truck during the first half of March compared with the same period in February, PierPass Inc. said.

From March 2 through March 15, nearly 303,000 import and export containers moved by truck into or out of the terminals, compared to nearly 207,000 from Feb. 2 through Feb. 15, according to gate transaction data collected by PierPass. These include containers moved during day shifts and the OffPeak shifts managed by PierPass on nights and Saturdays. The OffPeak program diverts about half of port truck trips out of Monday-through-Friday daytime traffic while roughly doubling the capacity of the Los Angeles and Long Beach ports.

According to the Marine Exchange of Southern California, there were 30 ships waiting to be unloaded at the Los Angeles and Long Beach ports on Monday March 16, down from 36 on Feb. 26.
