Interstate 780
Interstate 780 (I-780) is an east–west auxiliary Interstate Highway in the San Francisco Bay Area of Northern California. It runs from Curtola Parkway and Lemon Street in Vallejo to I-680 just north of the Benicia–Martinez Bridge in Benicia. It closely parallels the Carquinez Strait for its entire route. Originally, this segment was part of I-680 before that Interstate was extended and rerouted to Fairfield. The city-maintained Curtola Parkway continues west from I-80 to State Route 29 (SR 29) in Vallejo. Route description The I-780 state-maintained freeway begins at Lemon Street and Curtola Parkway, quickly crossing underneath I-80 at a cloverleaf interchange. The freeway passes through parts of unincorporated Solano County, then heads southeast along the Benicia State Recreation Area (a marsh). It then bypasses downtown Benicia through the hills to the north. I-780 ends at I-680 at the north end of the Benicia–Martinez Bridge, with I-680 heading sou ...

Federal Highway Administration
The Federal Highway Administration (FHWA) is a division of the United States Department of Transportation that specializes in highway transportation. The agency's major activities are grouped into two programs, the Federal-aid Highway Program and the Federal Lands Highway Program. Its role had previously been performed by the Office of Road Inquiry, Office of Public Roads and the Bureau of Public Roads. History Background The organization has several predecessor organizations and complicated history. The Office of Road Inquiry (ORI) was founded in 1893. In 1905, that organization's name was changed to the Office of Public Roads (OPR) which became a division of the United States Department of Agriculture. The name was changed again to the Bureau of Public Roads in 1915 and to the Public Roads Administration (PRA) in 1939. It was then shifted to the Federal Works Agency which was abolished in 1949 when its name reverted to Bureau of Public Roads under the Department of Comm ...

East Bay
The East Bay is the eastern region of the San Francisco Bay Area and includes cities along the eastern shores of the San Francisco Bay and San Pablo Bay. The region has grown to include inland communities in Alameda and Contra Costa counties. With a population of roughly 2.5 million in 2010, it is the most populous subregion in the Bay Area. Oakland is the largest city in the East Bay and the third largest in the Bay Area. The city serves as a major transportation hub for the U.S. West Coast, and its port is the largest in Northern California. Increased population has led to the growth of large edge cities such as Alameda, Concord, Emeryville, Fremont, Livermore, Pleasanton, San Ramon and Walnut Creek. History and development Although initial development in the larger Bay Area focused on San Francisco, the coastal East Bay came to prominence in the middle of the nineteenth century as the part of the Bay Area most accessible by land from the east.

Carquinez Bridge
The Carquinez Bridge is a pair of parallel bridges spanning the Carquinez Strait at the northeastern end of San Francisco Bay. They form the part of Interstate 80 between Crockett and Vallejo, California. The name Carquinez Bridge originally referred to a single cantilever bridge built in 1927, which was part of the direct route between San Francisco and Sacramento. A second parallel cantilever bridge was completed in 1958 to deal with the increased traffic. Later, seismic problems made the 1927 span unsafe in case of an earthquake, and led to the construction, and 2003 opening, of a replacement: a suspension bridge officially named the Alfred Zampa Memorial Bridge, in memory of iron worker Al Zampa, who played an integral role in the construction of numerous San Francisco Bay Area bridges. The Alfred Zampa Memorial Bridge carries southbound traffic from Vallejo to Crockett, and the 1958 cantilever span carries northbound traffic. History and description The first regular cross ...

Legislative Route 74 (California Pre-1964)
A legislature is an assembly with the authority to make laws for a political entity such as a country or city. They are often contrasted with the executive and judicial powers of government. Laws enacted by legislatures are usually known as primary legislation. In addition, legislatures may observe and steer governing actions, with authority to amend the budget involved. The members of a legislature are called legislators. In a democracy, legislators are most commonly popularly elected, although indirect election and appointment by the executive are also used, particularly for bicameral legislatures featuring an upper chamber. Terminology The name used to refer to a legislative body varies by country. Common names include: * Assembly (from ''to assemble'') * Congress (from ''to congregate'') * Council (from Latin 'meeting') * Diet (from old German 'people') * Estates or States (from old French 'condition' or 'status') * Parliament (from French ''parler'' 'to speak') ...

Legislative Route 7 (California Pre-1964)
Interstate 5 (I-5) is a major north–south route of the Interstate Highway System in the United States, stretching from the Mexican border at the San Ysidro crossing to the Canadian border near Blaine, Washington. The segment of I-5 in California runs across the length of the state from San Ysidro to the Oregon state line south of the Medford- Ashland metropolitan area. It is the longest interstate in California, and accounts for more than half of I-5's total length. It is the more important and most-used of the two major north–south routes on the Pacific Coast, the other being U.S. Route 101 (US 101), which is primarily coastal. I-5 links the major California cities of San Diego, Santa Ana, Los Angeles, Stockton, Sacramento, and Redding. The San Francisco Bay Area is about west of the highway. I-5 is known colloquially as "the 5" to Southern California residents and "5" to Northern California residents due to varieties in California English. I-5 also h ...

State Highway
A state highway, state road, or state route (and the equivalent provincial highway, provincial road, or provincial route) is usually a road that is either ''numbered'' or ''maintained'' by a sub-national state or province. A road numbered by a state or province falls below numbered national highways (Canada being a notable exception to this rule) in the hierarchy (route numbers are used to aid navigation, and may or may not indicate ownership or maintenance). Roads maintained by a state or province include both nationally numbered highways and un-numbered state highways. Depending on the state, "state highway" may be used for one meaning and "state road" or "state route" for the other. In some countries such as New Zealand, the word "state" is used in its sense of a sovereign state or country. By this meaning a state highway is a road maintained and numbered by the national government rather than local authorities. Countries Australia Australia's State Route system covers u ...

Automobile Blue Book
The ''Automobile Blue Book'' was an American series of road guides for motoring travelers in the United States and Canada published between 1901 and 1929. It was best known for its point-to-point road directions at a time when numbered routes generally did not exist (Wisconsin became the first state to number its highways in 1918). Origin Hartford automobile businessman and enthusiast Charles Howard Gillette initiated the series. It was first published in 1901, covering 62 routes across the American Northeastern metropolitan areas of Boston, New York, Philadelphia, Baltimore, and Washington, D.C. Gillette had originally intended the book to focus on routes that connected automobile supply stations, and included extensive reference sections on automobile repair and maintenance, but the book would find its most success focusing on routes between cities. Growth The ''Automobile Blue Book'' was published annually as a single volume through 1906, expanding to 3 volumes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County Road
A county highway (also county road or county route; usually abbreviated CH or CR) is a road in the United States and in the Canadian province of Ontario that is designated and/or maintained by the county highway department. Route numbering can be determined by each county alone, by mutual agreement among counties, or by a statewide pattern. Any county-maintained road, whether or not it is given a signed number, can be called a county road. Depending on the state or province and county, these roads can be named after geographic features, communities, or people. Or they may be assigned a name determined by a standardized grid reference: "East 2000" would be a north–south road running 20 blocks/miles/km east of the designated zero point. Many other variations are also used. Many locales have somewhat arbitrarily assigned numbers for all county roads, but with no number-signage at all or only on standard street name blades. County roads and highways vary greatly in design sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paved Road
A road surface (British English), or pavement (American English), is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway. In the past, gravel road surfaces, hoggin, cobblestone and granite setts were extensively used, but these have mostly been replaced by asphalt or concrete laid on a compacted base course. Asphalt mixtures have been used in pavement construction since the beginning of the 20th century and are of two types: metalled (hard-surfaced) and unmetalled roads. Metalled roadways are made to sustain vehicular load and so are usually made on frequently used roads. Unmetalled roads, also known as gravel roads, are rough and can sustain less weight. Road surfaces are frequently marked to guide traffic. Today, permeable paving methods are beginning to be used for low-impact roadways and walkways. Pavements are crucial to countries such as United States and Canada, which heavily depend on road tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Highway System (United States)
The National Highway System (NHS) is a network of strategic highways within the United States, including the Interstate Highway System and other roads serving major airports, ports, military bases, rail or truck terminals, railway stations, pipeline terminals and other strategic transport facilities. Altogether, it constitutes the largest highway system in the world. Individual states are encouraged to focus federal funds on improving the efficiency and safety of this network. The roads within the system were identified by the United States Department of Transportation (USDOT) in cooperation with the states, local officials, and metropolitan planning organizations (MPOs) and approved by the United States Congress in 1995. Legislation The Intermodal Surface Transportation Efficiency Act (ISTEA) in 1991 established certain key routes such as the Interstate Highway System, be included. The act provided a framework to develop a National Intermodal Transportation System which "co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Topographic Map
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large- scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and artificial features. A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map projection, coordinate system, ellipsoid and geodetic datum. Official topographic maps also adopt a national grid referencing system. Natural Resources Canada provides this description of topographic maps: Other authors define topographic maps by contrasting them with anoth ...
