Queensway Twin Bridges, Twin bridges in Long Beach, United States

The Queensway Twin Bridges are two parallel steel box-girder bridges over the Los Angeles River near its mouth in Long Beach. Each carries three lanes in each direction plus a 6 ft sidewalk, with a 500 ft main span between 350 ft side spans and a 45 ft clearance above low tide. The superstructure was prefabricated offsite and erected in 14 pieces over 11 days.

The bridges were designed by Martin A. Nishkian's consulting engineering firm and were known during planning as the Magnolia Avenue Bridge. Murphy Pacific prefabricated the steel superstructure in Richmond, California, and shipped it to Long Beach in 30 barge sections; the 290-foot drop-in spans were lifted into place on 26 May 1970. The crossing opened on 5 October 1970 and took its present name by 1972.

The bridges serve as backdrops for film and television productions and shape how the port city looks. Visitors may recognize these structures from various well-known media productions.

The bridges are passable by car but pedestrian access is limited since they carry heavy traffic. Visitors should avoid rush hours and be aware of busy road conditions.

Each bridge contains a central section that was installed as a prefabricated unit weighing hundreds of tons. This engineering solution allowed faster construction than traditional building methods.
