San Mateo–Hayward Bridge
The San Mateo–Hayward Bridge (commonly called the San Mateo 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 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 bridge is part of State Route 92 (SR 92), whose western terminus is at the city of Half Moon Bay on the Pacific coast. It links Interstate 880 (I-880) in the East Bay with U.S. Route 101 (US 101) on the peninsula. It is roughly parallel to, and lies between, the San Francisco–Oakland Bay Bridge and the Dumbarton Bridge. History and des ...

San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay meas ...

Orthotropic Deck
An orthotropic bridge or orthotropic deck is typically one whose fabricated deck consists of a structural steel deck plate stiffened either longitudinally with ribs or transversely, or in both directions. This allows the fabricated deck both to directly bear vehicular loads and to contribute to the bridge structure's overall load-bearing behaviour. The orthotropic deck may be integral with or supported on a grid of deck framing members, such as transverse floor beams and longitudinal girders. All these various choices for the stiffening elements, e.g., ribs, floor beams and main girders, can be interchanged, resulting in a great variety of orthotropic panels. Decks with different stiffnesses in longitudinal and transverse directions are called 'orthotropic'. If the stiffnesses are similar in the two directions, then the deck is called 'isotropic'. The steel deck-plate-and-ribs system may be idealized for analytical purposes as an orthogonal-anisotropic plate, hence the abbrev ...

Tung-Yen Lin
Tung-Yen Lin (; November 14, 1912 – November 15, 2003) was a Chinese-American structural engineer who was the pioneer of standardizing the use of prestressed concrete. Biography Born in Fuzhou, Republic of China (ROC), as the fourth of eleven children, he was raised in Beijing where his father was a justice of the ROC's Supreme Court. He did not begin formal schooling until age 11, and only so because his parents forged his birth year to be 1911 so that he would qualify. At only 14, entered Jiaotong University's Tangshan Engineering College (now Southwest Jiaotong University), having earned the top score in math and the second best score overall in the college entrance exams for his entering class. He graduated with a bachelor's degree in civil engineering in 1931 and left for the United States, where he earned his master's degree in civil engineering from the University of California, Berkeley in 1933. Lin's master's thesis was the first student thesis published by the Am ...

History Born in New York City and raised in Weehawken, New Jersey, Temko served as a U.S. Navy officer in World War II, graduated from Columbia University in 1947, and continued his graduate studies at the University of California, Berkeley, and at the Sorbonne in Paris, France. He taught for several years in France and produced a landmark book about the Cathedral of Notre Dame, ''Notre Dame of Paris,'' in 1955. He wrote architectural criticism for the ''San Francisco Chronicle'' from 1961 to 1993. He also taught city planning and the social sciences at the University of California, Berkeley and California State University, Hayward (now California State University, East Bay). Following Finnish-born architect Eero Saarinen's death in 1961, Temko published ''Eero Saarinen'' (1962), a critical examination of Saarinen's most famous works from the General Mot ...

Richmond–San Rafael Bridge
The Richmond–San Rafael Bridge (also officially named the John F. McCarthy Memorial Bridge) is the northernmost of the east–west crossings of the San Francisco Bay in California, USA. Officially named after California State Senator John F. McCarthy, it bridges 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. History Early proposals Proposals for a bridge were advanced in the 1920s, preceding the completion of the Golden Gate Bridge. In 1927, Roy O. Long of The Richmond–San Rafael Bridge, Incorporated, applied for a franchise to construct and operate a private toll bridge. The proposed 1927 Long bridge would have been a steel suspension bridge, carrying a roadway for a distance of at an estimated construction cost of . The bridge would afford a maximum vertical clearance of with a main span. Charles Derleth, Jr. was selected as the consulting engineer, after h ...

Stanford Axe
The Stanford Axe is a trophy awarded to the winner of the annual Big Game, a college football match-up between the University of California Golden Bears and the Stanford University Cardinal. The trophy consists of an axe-head mounted on a large wooden plaque, along with the scores of past Big Games. Cal currently holds the Axe after defeating Stanford 27–20 in the 2022 game. History Origins The Axe was originally a standard 12-inch lumberman's axe. It made its first appearance on April 13, 1899 during a Stanford rally when yell leaders used it to decapitate a straw man dressed in blue and gold ribbons while chanting the Axe yell, which was based on ''The Frogs'' by Aristophanes (Brekekekèx-koàx-koáx): Theft by University of California The Axe made its second appearance two days later on April 15, 1899 at a Cal-Stanford baseball game played at 16th Street and Folsom in San Francisco. Led by Billy Erb, the Stanford yell leaders paraded the Axe and used it to chop up b ...

Causeway
A causeway is a track, road or railway on the upper point of an embankment across "a low, or wet place, or piece of water". It can be constructed of earth, masonry, wood, or concrete. One of the earliest known wooden causeways is the Sweet Track in the Somerset Levels, England, which dates from the Neolithic age. Timber causeways may also be described as both boardwalks and bridges. Etymology When first used, the word ''causeway'' appeared in a form such as "causey way" making clear its derivation from the earlier form "causey". This word seems to have come from the same source by two different routes. It derives ultimately, from the Latin for heel, ''calx'', and most likely comes from the trampling technique to consolidate earthworks. Originally, the construction of a causeway utilised earth that had been trodden upon to compact and harden it as much as possible, one layer at a time, often by enslaved bodies or flocks of sheep. Today, this work is done by machines. The s ...
