The San Francisco–Oakland Bay Bridge, known locally as the Bay Bridge, is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 and the direct road between San Francisco and Oakland, it carries about 260,000 vehicles a day on its two decks. It includes one of the longest bridge spans in the United States.
A swing bridge is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot.
State Route 160 is a state highway in the U.S. state of California consisting of two sections. The longer, southern, section is a scenic highway through the alluvial plain of the Sacramento River, linking SR 4 in Antioch with Sacramento via the Antioch Bridge. The northern section, separated from the southern by Sacramento city streets, is the North Sacramento Freeway, running from the 16th Street Bridge over the American River to Interstate 80 Business towards Roseville.
The Richmond–San Rafael Bridge is the northernmost of the east–west crossings of California's San Francisco Bay, carrying Interstate 580 from Richmond on the east to San Rafael on the west. It opened in 1956, replacing ferry service by the Richmond–San Rafael Ferry Company, and was officially renamed in 1981 to honor California State Senator John F. McCarthy, who championed the bridge's creation.
State Route 61 is a state highway in the U.S. state of California, running along the eastern edge of Oakland International Airport and through Alameda. Two additional "hidden" state highways, State Route 112 and State Route 260, are also signed as part of SR 61, despite having legal descriptions separate from Route 61.
The Niles Canyon Railway (NCRy) is a heritage railway running on the first transcontinental railroad alignment through Niles Canyon, between Sunol and the Niles district of Fremont in the East Bay of the San Francisco Bay Area, in California, United States. The railway is listed on the National Register of Historic Places as the Niles Canyon Transcontinental Railroad Historic District. The railroad is operated and maintained by the Pacific Locomotive Association which preserves, restores and operates historic railroad equipment. The NCRy features public excursions with both steam and diesel locomotives along a well-preserved portion of the first transcontinental railroad.
The Fort Madison Toll Bridge is a tolled, double-decked swinging truss bridge over the Mississippi River that connects Fort Madison, Iowa, and unincorporated Niota, Illinois. A double-track railway occupies the lower deck of the bridge, while two lanes of road traffic are carried on the upper deck. The bridge is about 1 mile (1.6 km) long with a swing span of 525 feet (160 m), and was the longest and largest double-deck swing-span bridge in the world when constructed in 1927. It replaced an inadequate combination roadway/single-track bridge completed in 1887. The main river crossing consists of four 270-foot (82 m) Baltimore through truss spans and a swing span made of two equal arms, 266 feet (81 m) long. In 1999, it was listed in the National Register of Historic Places under the title, Fort Madison Bridge, ID number 99001035. It was also documented as survey number IA-62 by the Historic American Engineering Record, archived at the Library of Congress. Construction and photographic details were recorded at the time in Scientific American magazine.
The Posey and Webster Street Tubes are two parallel underwater tunnels connecting the cities of Oakland and Alameda, California, running beneath the Oakland Estuary. Both are immersed tubes, constructed by sinking precast concrete segments to a trench in the Estuary floor, then sealing them together to create a tunnel. The Posey Tube, completed in 1928, currently carries one-way (Oakland-bound) traffic under the Estuary, while the Webster Street Tube, completed in 1963, carries traffic from Oakland to Alameda.
The Tower Bridge is a vertical lift bridge across the Sacramento River, linking West Sacramento in Yolo County to the west, with the capital of California, Sacramento, in Sacramento County to the east. It has also been known as M Street Bridge. It was previously a part of U.S. Route 40 until that highway was truncated to east of Salt Lake City as well as US Route 99W, which served the western portion of the Sacramento Valley from Sacramento to Red Bluff. The bridge is maintained by the California Department of Transportation as part of State Route 275 and connects West Capitol Avenue and Tower Bridge Gateway in West Sacramento with the Capitol Mall in Sacramento.
The Park Street Bridge is a double-leaf bascule drawbridge spanning 372 feet of the Oakland Estuary in the San Francisco Bay Area. It links the cities of Oakland and Alameda. In a year, the bridge is opened approximately 1700 times and carries approximately 40,000 vehicles per work day. It was built when the Oakland Estuary was trenched, converting Alameda from a peninsula to an island.
The Fruitvale Bridge and the Fruitvale Avenue Bridge are parallel bridges that cross the Oakland Estuary, linking the cities of Oakland and Alameda in California. The Fruitvale Bridge is a vertical-lift Warren through truss railroad moveable bridge, while the Fruitvale Avenue Bridge is a steel stringer road bascule bridge that connects Fruitvale Avenue in Oakland with Tilden Way in Alameda.
The Illinois Central Missouri River Bridge, also known as the IC Bridge or the East Omaha Bridge, is a rail through truss double swing bridge across the Missouri River connecting Council Bluffs, Iowa, with Omaha, Nebraska. It is owned by the Canadian National Railway and is closed to all traffic. At 521 feet long, the second version of the bridge was the longest swing bridge in the world from when it was completed in 1903 through 1915. In 1975 it was regarded as the third longest swing bridge.
The San Mateo–Hayward Bridge is a bridge crossing the American state of California's San Francisco Bay, linking the San Francisco Peninsula with the East Bay. The bridge's western end is in Foster City, a suburb on the eastern edge of San Mateo. The eastern end of the bridge is in Hayward. It is the longest fixed-link bridge in California and the 25th longest in the world by length. The bridge is owned by the state of California, and is maintained by California Department of Transportation (Caltrans), the state highway agency. Further oversight is provided by the Bay Area Toll Authority (BATA).
The High Street Bridge is a double-leaf bascule drawbridge spanning 296 feet of the Oakland Estuary in the San Francisco Bay Area, California, United States. It links the cities of Oakland and Alameda. The bridge is opened approximately 1,400 times a year. The bridge carries an average of 26,000 vehicles per year. The bridge was built when the Oakland Estuary was trenched, converting Alameda from a peninsula to an island.
The Dumbarton Rail Bridge lies just to the south of the Dumbarton road bridge. Built in 1910, the rail bridge was the first structure to span San Francisco Bay, shortening the rail route between Oakland and San Francisco by 26 miles (42 km). The last freight train traveled over the bridge in 1982, and it has been proposed since 1991 to reactivate passenger train service to relieve traffic on the road bridges, though this would entail a complete replacement of the existing bridge. Part of the western timber trestle approach collapsed in a suspected arson fire in 1998.
The Rio Vista Bridge is a continuous truss span with a vertical-lift bridge in the middle which carries California State Route 12 across the Sacramento River at Rio Vista, California. The present bridge was completed in 1960 and is one of several moveable bridges spanning rivers in the Sacramento–San Joaquin River Delta. It is named after Helen Madere, who served as vice-mayor of Rio Vista. As of 2013 the bridge carries approximately 21,000 cars per day.
The San Leandro Bay Bridge, better known as the Bay Farm Island Bridge, is a single-leaf bascule drawbridge spanning the San Leandro Channel, the inlet of San Leandro Bay within the San Francisco Bay Area, California, United States. It carries California State Route 61 and links the main island of Alameda with Bay Farm Island within the city of Alameda. The present bridge was completed in 1953; it is paralleled by a second bridge devoted to pedestrian and bicycle traffic, the Bay Farm Island Bicycle Bridge.
The Marpole Bridge (1889–1957), a.k.a. Eburne Bridge, North Arm Bridge, Sea Island Bridge, or Middle Arm Bridge, was consecutive crossings over the north and middle arms of the Fraser River in Metro Vancouver.
