San Diego River
The San Diego River is a 52 mi (84 km) river in San Diego County, California. It originates in the Cuyamaca Mountains northwest of the town of Julian, then flows to the southwest until it reaches El Capitan Reservoir, the second-largest reservoir in the river's watershed at . Below El Capitan Dam, the river runs west through Santee and San Diego. While passing through Tierrasanta it goes through Mission Trails Regional Park, one of the largest urban parks in America. It flows near Mission San Diego de Alcalá. The river's valley downstream from there is known as Mission Valley for that reason. The valley forms a transportation corridor for Interstate 8 and the San Diego Trolley's Green Line. The river discharges into the Pacific Ocean near the entrance to Mission Bay, forming an estuary. History The river has changed its course several times in recorded history. Prior to 1821, the San Diego River usually entered San Diego Bay. In the fall of 1821, however, a flood chan ...

Concrete Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest viaduct in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinforced Concrete
Reinforced concrete, also called ferroconcrete or ferro-concrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (known as rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Cajon Boulevard
El Cajon Boulevard is a major east–west thoroughfare through San Diego, La Mesa and El Cajon, California. Before the creation of Interstate 8 it was the principal automobile route from San Diego to El Cajon, the Imperial Valley, and points east as U.S. Route 80; it is now signed as a business loop of Interstate 8. Route description The boulevard now consists of two disconnected portions, one in San Diego and La Mesa, and the other in El Cajon. The central section through La Mesa's Grossmont Pass was built over by Interstate 8. It has been cited as a prime example of a commercial strip whose growth and development was shaped by the automobile, as opposed to the parallel University Avenue commercial strip whose growth was shaped by the trolley. History It was formerly part of U.S. Route 80, and became a business loop for Interstate 8 when U.S. Route 80 was decommissioned and replaced by the interstate. It is designated as a historic highway by the state of California. Only p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate 15
Interstate 15 (I-15) is a major Interstate Highway in the Western United States, running through Southern California and the Intermountain West.

The stretches of I-15 in Idaho, Utah, and Arizona have been designated as the "Veterans Memorial Highway". The southern end is at a junction with I-8 and State Route 15 (SR 15) in San Diego, and the northern end is at a connection with Alberta Highway 4 at the Sweetgrass–Coutts Border Crossing. I-15 was built to connect the Inland Empire with San Diego in California, facilitate tourism access to Las Vegas, prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California State Route 15
Route 15, consisting of the contiguous segments of State Route 15 (SR 15) and Interstate 15 (I-15), is a major north–south state highway and Interstate Highway in the U.S. state of California, connecting San Diego, Riverside, and San Bernardino counties. The route consists of the southernmost of I-15, which extends north through Nevada, Arizona, Utah, Idaho, and Montana to the Canada–US border. It is a major thoroughfare for traffic between San Diego and the Inland Empire, as well as between Southern California; Las Vegas, Nevada; and the Intermountain West. South of its junction at I-8 in San Diego, the highway becomes SR 15, extending to I-5, about from the Mexico–United States border. This segment was initially signed as a state route instead of an Interstate, but it is being upgraded to Interstate standards so it would become part of I-15 in the future. Including this segment, the entire length of Route 15 is in California. I-15 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California State Route 94

California State Route 905
State Route 905 (SR 905), also known as the Otay Mesa Freeway, is an state highway in San Diego, in the southwestern part of the U.S. state of California. It connects I-5 and I-805 in San Ysidro to the Mexican border at Otay Mesa. The entire highway from I-5 to the international border is a freeway with a few exits that continues east from the I-805 interchange before turning southeast and reaching the border. SR 905 formerly followed Otay Mesa Road, which had been in existence since at least 1927. Before it was SR 905, the route was first designated as part of SR 75, before it was redesignated as SR 117. The freeway was completed between I-5 and Otay Mesa Road in 1976. The border crossing opened in 1985 after several delays in obtaining funding for construction on what would become SR 905. After becoming SR 905 in 1986, the highway was converted to first an expressway in 2000 and then a freeway in 2010 and 2011. This state route is ...
