Commodore Schuyler F. Heim Bridge
The Commodore Schuyler F. Heim Bridge was a vertical-lift bridge in the Port of Los Angeles. Dedicated on January 10, 1948, the bridge allowed State Route 47 (the Terminal Island Freeway) to cross over the Cerritos Channel. Named after Schuyler F. Heim, who was in command of the Naval Air Station on Terminal Island in 1942, the bridge was one of the largest vertical-lift bridges on the West Coast. At the time of its opening, it was the highest in the country with the deck weighing about . Its towers are tall above the roadway deck and about tall when measured from the water level at high water. The bridge was decommissioned on October 12, 2015 and replaced by a new, six-lane fixed-span bridge in order to meet current safety and earthquake standards. A replacement bridge, tentatively titled ''State Route 47 Schuyler Heim Bridge Replacement'', was completed in September 2020.

Gerald Desmond Bridge (2020-present)
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 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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Route 47 (California)
State Route 47 (SR 47) is a state highway in the U.S. state of California, connecting Terminal Island to the mainland in the Los Angeles area. From its south end at I-110 in San Pedro, it heads east across the Vincent Thomas Bridge to the island and the end of state maintenance. The state highway begins again at the junction with I-710 on Terminal Island, crossing the Schuyler Heim Bridge north to the mainland and the second terminus, where SR 103 begins. Signage continues along a locally maintained route, mainly Alameda Street, to the Gardena Freeway ( SR 91) in Compton, and an unconstructed alignment follows the same corridor to the Santa Monica Freeway (I-10) near downtown Los Angeles. Route description State Route 47 begins at the south end of the Harbor Freeway (I-110) in the Los Angeles neighborhood of San Pedro and heads east to the Vincent Thomas Bridge, with only one interchange — at Harbor Boulevard — before the 1963 suspension bridge over the main chan ...

Air Draft
Air draft (or air draught) is the distance from the surface of the water to the highest point on a vessel. This is similar to the " deep draft" of a vessel which is measured from the surface of the water to the deepest part of the hull below the surface, but air draft is expressed as a height, not a depth. Clearance below The vessel's " clearance" is the distance in excess of the air draft which allows a vessel to pass safely under a bridge or obstacle such as power lines, etc. A bridge's "clearance below" is most often noted on charts as measured from the surface of the water to the under side of the bridge at the chart datum Mean High Water (MHW), a less restrictive clearance than Mean Higher High Water (MHHW). In 2014, the United States Coast Guard reported that 1.2% of the collisions it investigated in the recent past were due to vessels attempting to pass underneath structures with insufficient clearance.

Liftspan Bridge
A vertical-lift bridge or just lift bridge is a type of movable bridge in which a span rises vertically while remaining parallel with the deck. The vertical lift offers several benefits over other movable bridges such as the bascule and swing-span bridges. Generally speaking, they cost less to build for longer moveable spans. The counterweights in a vertical lift are only required to be equal to the weight of the deck, whereas bascule bridge counterweights must weigh several times as much as the span being lifted. As a result, heavier materials can be used in the deck, and so this type of bridge is especially suited for heavy railroad use. The biggest disadvantage to the vertical-lift bridge (in comparison with many other designs) is the height restriction for vessels passing under it, due to the deck remaining suspended above the passageway. Although most vertical-lift bridges use towers, each equipped with counterweights, some use hydraulic jacks located below the deck. A ...

Commodore (United States)
Commodore was an early title and later a rank in the United States Navy, United States Coast Guard and the Confederate States Navy, and also has been a rank in the United States Public Health Service Commissioned Corps and the National Oceanic and Atmospheric Administration Commissioned Officer Corps (NOAA Corps) and its ancestor organizations. For over two centuries, the designation has been given varying levels of authority and formality. Today, it is no longer a specific rank within active-duty or reserve forces or in the Public Health Service Commissioned Corps or NOAA Corps, but it remains in use as an ''honorary title'' within the U.S. Navy and U.S. Coast Guard for those senior captains (pay grade O-6) in command of operational organizations composed of multiple independent subordinate naval units (e.g., multiple independent ships or aviation squadrons). However, "commodore" is a rank that is actively used to this day in the United States Coast Guard Auxiliary, the civ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Air Base San Pedro
Naval Air Base San Pedro, NAS Terminal Island was a US Navy World War II 410-acre airfield on Terminal Island in San Pedro, California part of the City of Los Angeles. Before the Navy took control of the airfield, the airstrip was the civilian Allen Field. Allen Field was built in 1927 by filling with sand the Port of Los Angeles and enlarging Terminal Island. Terminal Island is located between San Pedro Harbor and Long Beach Harbor. Allen Field was serviced by the Pacific Electric and pedestrian ferries. The air terminal has three runways in a triangle shape, two short runways and one 4,200 foot runway. A large seaplane ramp was also built at the Terminal. A Naval Air Reserve Training Facility was built next to Allen Field in 1927 and used the runway - ramp. Civilian use ended in 1935 and the site began an Air Base, later it was renamed Reeves Field San Pedro, after Rear Admiral Joseph M. Reeves. On on 25 September 1941 Naval Air Base San Pedro became part of Naval Operating Base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henry Ford Bridge
The Henry Ford Bridge, also known as the Badger Avenue Bridge, is a bridge located in Los Angeles County, Southern California. It carries the Pacific Harbor Line railroad across the Cerritos Channel to Terminal Island from San Pedro, to serve the Port of Los Angeles and Port of Long Beach. It was built to accommodate operations at the Ford Long Beach Assembly plant which opened in 1930 and was closed in 1959. The original 1924 bascule bridge was dismantled and replaced in 1996 by a vertical-lift bridge. Bascule bridge The contract for the bascule bridge was placed by The Los Angeles Board of Harbor Commissioners in 1922. The bridge was designed by Joseph Baermann Strauss and fabricated by the American Bridge Company. It was formed of a pair of trunnion bascule leaves which formed a one span Warren through-truss. There were two tower spans and two timber approaches. See also *Commodore Schuyler F. Heim Bridge *Vincent Thomas Bridge *Bridges in Los Angeles County, Cal ...
