Long Beach International Gateway
Long Beach International Gateway

The Long Beach International Gateway is a cable-stayed bridge that carries six lanes of Interstate 710 and a bicycle/pedestrian path in Long Beach, California, west across the Back Channel to Terminal Island. The bridge replaced the Gerald Desmond Bridge, which was completed in 1968 and named after Gerald Desmond, a prominent civic leader and a former city attorney for the City of Long Beach. The 1968 steel arch bridge developed numerous issues, and the Port of Long Beach decided it would be best, from an economical perspective, that the bridge be replaced. After several years of studies, a cable-stayed bridge with 205 feet (62 m) of vertical clearance to be built north of the existing bridge was identified as the preferred alternative in the final environmental impact report (2010 FEIR).The new bridge allows access to the port for the tallest container ships after the older bridge is demolished. It is the first long-span cable-stayed bridge in California and the first and only cable-stayed bridge in the Los Angeles metropolitan area. For the bridge to be so tall, long approaches were required to allow trucks to cross. A joint venture of Parsons Transportation Group and HNTB performed preliminary engineering for the main span and the approaches. Earlier reports had studied and discarded various alternatives, including an alternative alignment with a new bridge south of the existing bridge, rehabilitation of the existing bridge, and a tunnel instead of an elevated bridge.

United Concrete Pipe Corporation
United Concrete Pipe Corporation

United Concrete Pipe Corporation main construction was of main water pipeline lines, building concrete bridges, concrete roads, and foundations for buildings. United Concrete Pipe was established in 1919 in Ventura, California, by (Thomas) Tom P. Polich. In 1924 Steve Krai and B. J. Ukropina became partners with Polich. Tom Polich was born on March 22, 1888, in Serbia and came to the US in 1905. Polich worked for a concrete company in Van Nuys, California, before starting his own company. His first contact was installing a irrigation system in Tuttle, California. In the 1930s under the Works Progress Administration the company grew to nine plants and became a general contractor, not just a pipe company. Plants were in California, Texas and New Mexico. In 1953 the three started a new parallel joint venture Ukropina-Polich-Krai of San Gabriel, a general contractor company. United Concrete Pipe Corporation headquarters was at 85th St. and Vermont Ave., Los Angeles, California. One Works Progress Administration project was the Wawona Tunnel built in 1933. In 1937 United Concrete Pipe completed a Works Progress Administration project the Mad River Water Supply Project in Eureka, California. United Concrete Pipe Corporation last plant closed in 1994, at Riverside, California.In 1943, United Concrete Pipe established a shipyard division in Long Beach, California, to build small coasters ships for the US Army under the Emergency Shipbuilding Program. The shipyard of United Concrete Pipe was in Long Beach at breath 83, at the north side of channel 2, at the entrance to the channel. Unique to the boatyard was the assembly line railway the ships were built on. As the boat was built it would move down the rail track towards the water. The steel for the shipyard was shaped by the United Concrete Pipe Baldwin Park, California, plant. The Army ships were 176-foot, a beam of 30 feet, a draft of 8 feet, and were 935 tons loaded. Power was from two General Motors Clevland diesel engine each with 500 hp. The first ship was complete on March 23, 1944.

Craig Shipbuilding Company
Craig Shipbuilding Company

Craig Shipbuilding was a shipbuilding company in Long Beach, California. To support the World War I demand for ships Craig Shipbuilding shipyard switched over to military construction and built: US Navy Submarines and Cargo Ships. Craig Shipbuilding was started in 1906 by John F. Craig. John F. Craig had worked in Toledo, Ohio with his father, John Craig (1838-1934), and Blythe Craig, both shipbuilders, their first ship was built in 1864 at Craig Shipbuilding Toledo. John F. Craig opened his shipbuilding company in Port of Long Beach on the south side of Channel 3, the current location of Pier 41 in the inner harbor, becoming the port's first shipyard. In 1908 Craig Shipbuilding was given the contract to finishing dredging of the Port of Long Beach inner harbor and to dredge the channel connecting it to the Pacific ocean. In 1917 Craig sold the shipyard to the short-lived California Shipbuilding Company. but then opened a new shipyard next to the one he just sold and called it the Long Beach Shipbuilding Company. The Long Beach Shipbuilding Company built cargo ships in 1918, 1919, and 1920 for the United States Shipping Board. In 1918 California Shipbuilding started to have difficulties completing contracts that it had purchased with the Craig Shipyard, including two submarines and a lighthouse tender. In 1921, Craig purchased his original shipyard back and renamed it back to Craig Shipbuilding. At the same time he renamed the Long Beach Shipbuilding to Craig Shipbuilding and ran both as one company. The tow shipyard did repair work on built yachts. The United States Maritime Commission started a shipbuilding program in 1939, to support the World War 2 demand for ships. Craig leased the Long Beach Shipbuilding yard to the Consolidated Steel Corporation. Consolidated Steel built Type C1-B and C1-M cargo merchant ships and two Type P1 passenger ships at the leased yard from prefabricated sections erected at their Maywood plant inland. Consolidated Steel operated two other large shipyards, one nearby in the Port of Los Angeles West Basin in Wilmington, which was also supplied by Maywood, the other in Orange, Texas, and two other small boatyards. After World war 2, the Consolidated-leased yard closed. Craig shipyard continued to do repair work as the Long Beach Marine Repair and closed in 1970.
