Carnival Imagination in Long Beach

(12:37 p.m. EDT) -- Carnival Cruise Line will more than double the size of its Long Beach terminal, near Los Angeles, allowing the infrastructure to accommodate newer ships with larger numbers of passengers.

Slated for completion in 2017, the expansion will increase the line's usable terminal space from 66,000 square feet to 142,000 square feet. In a statement, Carnival Cruise Line President Christine Duffy said the move will make Long Beach one of the line's largest homeport facilities.

Carnival has always used a portion of the port's Geodesic Dome (formerly the site of Howard Hughes' Spruce Goose attraction) to house operations. Under the new agreement, it will utilize the entire dome, allowing two-way traffic -- meaning embarking passengers can arrive at the terminal prior to the completion of the previous sailing's disembarkation.

The expansion also will create additional parking and add electrical hookups for ships in an effort to reduce exhaust emissions.

Long Beach is home to Carnival Inspiration and Carnival Imagination, both of which focus on three- and four-night Baja cruises, and Carnival Miracle, which offers seven-night Mexican Riviera cruises as well as 14- and 15-night Hawaii and Alaska cruises.
