Caldecott Tunnel
The Caldecott Tunnel is an east–west highway tunnel through the Berkeley Hills between Oakland and Orinda, California. Its four bores carry California State Route 24. Named after Thomas E. Caldecott, former mayor of Berkeley, it opened in 1937 as a two-bore tunnel. The third bore opened in 1964 and the fourth bore in 2013. Currently, the two oldest bores carry eastbound traffic and the two newest bores carry westbound traffic. Description The east–west tunnel is signed as a part of California State Route 24 and connects Oakland to central Contra Costa County. It is named after Thomas E. Caldecott (1878–1951), who was mayor of Berkeley in 1930–1932, a member of the Alameda County Board of Supervisors in 1933–1945, and president of Joint Highway District 13, which built the first two bores. Bore 1 (the southernmost bore) and Bore 2 were completed in 1937; they are in length and carry two lanes each of eastbound traffic. Bore 3, completed in 1964, is in length. Bore ...

Reversible Lane
A reversible lane (British English: tidal flow) is a lane in which traffic may travel in either direction, depending on certain conditions. Typically, it is meant to improve traffic flow during rush hours, by having overhead traffic lights and lighted street signs notify drivers which lanes are open or closed to driving or turning. Reversible lanes are also commonly found in tunnels and on bridges, and on the surrounding roadways – even where the lanes are not regularly reversed to handle normal changes in traffic flow. The presence of lane controls allows authorities to close or reverse lanes when unusual circumstances (such as construction or a traffic mishap) require use of fewer or more lanes to maintain orderly flow of traffic. Separation of flows Some more recent implementations of reversible lanes use a movable barrier to establish a physical separation between allowed and disallowed lanes of travel. In some systems, a concrete barrier is moved during low-traffic peri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tule Fog
Tule fog () is a thick ground fog that settles in the San Joaquin Valley and Sacramento Valley areas of California's Central Valley. Tule fog forms from late fall through early spring (California's winter season) after the first significant rainfall. The official time frame for tule fog to form is from November 1 to March 31. This phenomenon is named after the tule grass wetlands (''tulares'') of the Central Valley. Tule fog is the leading cause of weather-related accidents in California. Formation Tule fog is a radiation fog, which condenses when there is a high relative humidity (typically after a heavy rain), calm winds, and rapid cooling during the night. The nights are longer in the winter months, which allows an extended period of ground cooling, and thereby a pronounced temperature inversion at a low altitude. In California, tule fog can extend from Bakersfield to Red Bluff, covering a distance of over . Tule fog occasionally drifts as far west as the San Francisco B ...

San Francisco Fog
Fog is a common weather phenomenon in the San Francisco Bay Area as well as along the entire coastline of California extending south to the northwest coast of the Baja California Peninsula. The frequency of fog and low-lying stratus clouds is due to a combination of factors particular to the region that are especially prevalent in the summer. Another type of fog, tule fog, can occur during the winter. There are occasions when both types can occur simultaneously in the Bay Area. The prevalence of fog in the San Francisco Bay Area has decreased, and this trend is typically attributed to climate change. Ocean moisture The Pacific Ocean contributes to the frequency of fog by providing atmospheric moisture and by its temperature. It is also the major source of nuclei for the condensation of moisture from vapor into cloud droplets. Moisture evaporated from the ocean surface over hundreds, even thousands of miles of the open Pacific is carried to California from various directions. ...

Treasure Island, San Francisco
Treasure Island is an artificial island in the San Francisco Bay and a neighborhood in the City and County of San Francisco. Built in 1936–37 for the 1939 Golden Gate International Exposition, the island's World's Fair site is a California Historical Landmark. Buildings there have been listed on the National Register of Historic Places, and the historical Naval Station Treasure Island, an auxiliary air facility (for airships, blimps, dirigibles, planes and seaplanes), are designated in the Geographic Names Information System. Geography The San Francisco census tract that includes Treasure Island extends up and down the San Francisco Bay and includes a small uninhabited tip of western Alameda Island. Yerba Buena and Treasure islands together have a land area of with – in 2010 – a total population of 2,500. Treasure Island alone is 393 acres. It is connected by a causeway to Yerba Buena Island, which in turn has on- and off-ramps to Interstate 80 on the San Francisco–Oak ...

Financial Crisis Of 2007–2008
Finance is the study and discipline of money, currency and capital assets. It is related to, but not synonymous with economics, the study of production, distribution, and consumption of money, assets, goods and services (the discipline of financial economics bridges the two). Finance activities take place in financial systems at various scopes, thus the field can be roughly divided into personal, corporate, and public finance. In a financial system, assets are bought, sold, or traded as financial instruments, such as currencies, loans, bonds, shares, stocks, options, futures, etc. Assets can also be banked, invested, and insured to maximize value and minimize loss. In practice, risks are always present in any financial action and entities. A broad range of subfields within finance exist due to its wide scope. Asset, money, risk and investment management aim to maximize value and minimize volatility. Financial analysis is viability, stability, and profitability a ...

1991 Oakland Firestorm
: The Oakland firestorm of 1991 was a large suburban wildland–urban interface conflagration that occurred on the hillsides of northern Oakland, California, and southeastern Berkeley, California, Berkeley over the weekend of October 19–20, 1991, before being brought under full control on October 23. The official name of this incident by Cal Fire is the Tunnel Fire. However, it is also commonly referred to as the Oakland Hills firestorm or the East Bay Hills fire.

Smoke Inhalation
Smoke inhalation is the breathing in of harmful fumes (produced as by-products of combusting substances) through the respiratory tract. This can cause smoke inhalation injury (subtype of acute inhalation injury) which is damage to the respiratory tract caused by chemical and/or heat exposure as well as possible systemic toxicity after smoke inhalation. Smoke inhalation can occur from fires of various sources such as residential, vehicle, and wildfires. Morbidity and mortality rates in fire victims with burns are increased in those with smoke inhalation injury. Victims of smoke inhalation injury can present with cough, difficulty breathing, low oxygen saturation, smoke debris and/or burns on the face. Smoke inhalation injury can affect the upper respiratory tract (above the larynx), usually due to heat exposure, or the lower respiratory tract (below the larynx), usually due to exposure to toxic fumes. Initial treatment includes taking the victim away from the fire and smoke, give 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caldecott Tunnel Fire
The Caldecott Tunnel fire killed seven people in the third (then-northernmost) bore of the Caldecott Tunnel, on State Route 24 between Oakland and Orinda in the U.S. state of California, just after midnight on 7 April 1982. It is one of the few major tunnel fires involving a cargo normally considered to be highly flammable, namely gasoline. At the time of the fire, the Caldecott tunnel complex consisted of three bores side-by-side, each . The then-northernmost bore, where the fire occurred, is dedicated to westbound traffic, traveling from Orinda to Oakland. It has a slope of approximately 4.7%, going downhill from the entry portal to the exit portal. Description of events Shortly after midnight, a westbound driver drifted out of lane; she was later ruled to have been legally drunk at the time. Her car struck the tunnel wall, stopping in the left-hand (fast) lane almost halfway through the tunnel. The driver got out to inspect the damage. The initial crash created a bottlen ...
