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 the intersection of Curtola Parkway and Lemon Street in Vallejo east 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 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-68 ...

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 With the coming of the bicycle in the 1890s, interest grew regarding the improvement of streets and roads in America. The traditional method of putting the burden on maintaining roads on local landowners was increasingly inadequate. In 1893, the federal Office of Road Inquiry (ORI) was founded; in 1905, it was renamed the Office of Public Roads (OPR) and made a division of the United States Department of Agriculture. Demands grew for local and state government to take charge. With the coming of the automobile, urgent efforts were made to upgrade and moderniz ...

Marsh
In ecology, a marsh is a wetland that is dominated by herbaceous plants rather than by woody plants.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p More in general, the word can be used for any low-lying and seasonally waterlogged terrain. In Europe and in agricultural literature low-lying meadows that require draining and embanked polderlands are also referred to as marshes or marshland. Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legislative Route 74 (California Pre-1964)
A legislature (, ) is a deliberative assembly with the legal authority to make laws for a political entity such as a country, nation or city on behalf of the people therein. They are often contrasted with the executive and judicial powers of government. Legislatures can exist at different levels of government–national, state/provincial/regional, local, even supranational (such as the European Parliament). Countries differ as to what extent they grant deliberative assemblies at the subnational law-making power, as opposed to purely administrative responsibilities. 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 f ...

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, running largely parallel to the Pacific Coast between the Mexican border and the Canadian border. The segment of I-5 in California runs across the length of the state from the Mexican border at the San Ysidro Port of Entry in the San Ysidro neighborhood of San Diego to the Oregon state line south of the Medford- Ashland metropolitan area. It is the longest interstate in California at , and accounts for more than half of I-5's total length of . It is also the second longest stretch of Interstate Highway (and the longest for a north-south Interstate) with a single designation within a single state after I-10 in Texas. 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Route number, 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 Trans-Canada Highway#Jurisdiction and designation, 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. By co ...

Automobile Blue Book
The ''Automobile Blue Book'' was an American Book series, series of road Guide book, guides for driving, 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 Route number, numbered routes generally did not exist (Wisconsin became the first state to number its highways in 1918). Origin Hartford, Connecticut, Hartford automobile businessman and enthusiast Charles Howard Gillette initiated the series. It was first published in 1901, covering 62 routes across the Northeastern United States, American Northeastern metropolitan areas of Boston, New York City, 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.

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 stand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paved Road
A road surface (British English) or pavement (North 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, macadam, hoggin, cobblestone and sett (paving), granite setts were extensively used, but these have mostly been replaced by Asphalt concrete, 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 or dirt roads, are rough and can sustain less weight. Road surfaces are frequently road surface marking, marked to guide traffic. Today, permeable paving methods are beginning to be used for low-impact roadways and walkways to prevent flooding. Paveme ...

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 ...
