Robin Williams Tunnel
The Waldo Grade is a highway grade between the Golden Gate Bridge and Marin City along U.S. Route 101 and State Route 1. It is defined as the stretch of roadway between the Spencer Offramp and Marin City, within the city of Sausalito. This grade is traversed by a full freeway multi-lane highway facility. This portion of US 101/SR 1 is an important link in surface transportation connecting the city of San Francisco to Marin County and the North Bay. Nearby locations to the Waldo Grade include: the city of Sausalito, the U.S. Army Corps of Engineers Bay Model, The Marine Mammal Center and the Golden Gate National Recreation Area. It, and nearby Waldo Point along Richardson Bay between Sausalito and Mill Valley, is named after 1850s California politician William Waldo. Robin Williams Tunnel A tunnel officially known as the Robin Williams Tunnel (previously and informally referred to as the Waldo Tunnel) is located at the highest elevation on US 101/SR 1 al ...

Robert Halligan
Robert W. Halligan (1926 – February 15, 1999) was an American engineer and information officer of the California Department of Transportation. During his 45-year career there, he helped state Highway 24, and convinced CalTrans to celebrate the 50th anniversary of the Bay Bridge by stringing lights on the cables of the suspension spans – a temporary change which later became permanent. He was also known for his enthusiasm and showmanship: Known as a "walking museum of transportation lore", he moved from engineering to public affairs in the 1960s, where he arranged to have airplanes land on new freeways, orchestrated parades of covered wagons, and even antique car caravans, and high school bands. He was responsible for highway 280's designation as "The world's most beautiful freeway". Robin Williams Tunnel Halligan is most remembered for convincing the agency to paint a rainbow on the Robin Williams Tunnel, on Highway 101 between Mill Valley Mill Valley is a city i ...

Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of inc ...

US 101 In CA
U.S. Route 101 (US 101) is a major north–south United States Numbered Highway, stretching from Los Angeles, California to Tumwater, Washington. The California portion of US 101 is one of the last remaining and longest U.S. Routes still active in the state, and the longest highway of any kind in California. US 101 was also one of the original national routes established in 1926. Significant portions of US 101 between the Los Angeles area and the San Francisco Bay Area follow El Camino Real, the commemorative route connecting the former Alta California's 21 missions. Although the highway has been superseded in overall importance for transportation through the state by Interstate 5 (I-5), US 101 continues to be the major coastal north–south route that links the Greater Los Angeles Area, the Central Coast, the San Francisco Bay Area, and the North Coast (Redwood Empire). Generally referred to as "101" by residents of Northern California, in Southe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated grade (slope), slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the She ...

Tunnel Near Golden Gate Bridge - San Francisco
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
