The Dwight D. Eisenhower National System of Interstate and Defense Highways (commonly known as the Interstate Highway System, Interstate Freeway System, Interstate System, or simply the Interstate) is a network of freeways that forms a part of the National Highway System of the United States. The system is named for President Dwight D. Eisenhower, who championed its formation. Construction was authorized by the Federal Aid Highway Act of 1956, and the original portion was completed 35 years later. The network has since been extended, and as of 2010[update], it had a total length of 47,182 miles (75,932 km), making it the world's second longest after China's. As of 2010[update], about one-quarter of all vehicle miles driven in the country use the Interstate system. The cost of construction has been estimated at $425 billion (in 2006 dollars).
Transportation in the United States is facilitated by road, air, rail, and water networks(Boats). The vast majority of passenger travel occurs by automobile for shorter distances, and airplane or railroad for some people, for longer distances. In descending order, most cargoes travel by railroad, truck, pipeline, or boat; air shipping is typically used only for perishables and premium express shipments.
The presidency of Dwight D. Eisenhower, from 1953 to 1961, followed double defeats of Democrat Adlai Stevenson in the 1952 and 1956 elections. Ike, as he was popularly known, ended the Korean war and presided over eight years of relative peace and moderate economic growth, during which no inflation occurred and the debt kept to a minimum. His main legacy is the Interstate Highway System.
Texas state highways are a network of highways owned and maintained by the U.S. state of Texas. The Texas Department of Transportation (TxDOT) is the state agency responsible for the day-to-day operations and maintenance of the system. In addition to the nationally-numbered Interstate highways and U.S. highways, the highway system consists of a main network of state highways, loops, spurs, and beltways that provide local access to the Interstate Highways, U.S. Highways, and state highways. The system also includes a large network of farm to market roads that connect rural areas of the state with urban areas and the rest of the state highway system. The state also owns and maintains some park and recreational roads that are located near and within state and national parks as well as recreational areas. All state highways, regardless of classification, are paved roads. The Old San Antonio Road, also known as the El Camino Real, is the oldest highway in the United States, first being blazed in 1691. The length of the highways varies from I-10's 878.6 miles (1,414.0 km) inside the state borders to Spur 200 at just 0.05 miles (0.080 km) long.
Baltimore (//, colloquially /ˈbɔl.mɔr/) is the largest city in the U.S. state of Maryland and the 26th largest city in the country. It is located in the central area of the state along the tidal portion of the Patapsco River, an arm of the Chesapeake Bay. The independent city is often referred to as Baltimore City to distinguish it from surrounding Baltimore County. Founded in 1729, Baltimore is the second largest seaport in the Mid-Atlantic United States and is situated closer to Midwestern markets than any other major seaport on the East Coast. Baltimore's Inner Harbor was once the second leading port of entry for immigrants to the United States and a major manufacturing center. After a decline in manufacturing, Baltimore shifted to a service-oriented economy, with the Johns Hopkins Hospital and Johns Hopkins University serving as the city's top two employers.
At 621,342 as of July 1, 2012, the population of Baltimore increased by 1,100 residents over the previous year ending over six decades of population loss since its peak in 1950. The Baltimore Metropolitan Area has grown steadily to approximately 2.7 million residents in 2010; the 20th largest in the country. Baltimore is also a principal city in the larger Baltimore–Washington metropolitan area of approximately 8.4 million residents.
The primary highway system makes up over 9,000 miles (14,000 km), a mere 8 percent of the U.S. state of Iowa's public road system. The Iowa Department of Transportation is responsible for the day-to-day maintenance of the primary highway system, which consists of Interstate Highways, United States Highways, and Iowa state highways. Currently, the longest primary highway is U.S. Route 30 at 332 miles (534 km). The shortest highway is Interstate 129 at 0.27 miles (0.43 km).
The 20th Century was a transformative time for vehicular transportation. In the early years of the century, roads were problematic at best – dusty dirt roads when dry and impassably muddy when wet. Over time, federal money was set aside and bonds were issued allowing the roads to be paved. The U.S. Highway and Interstate Highway Systems connected Iowa to the rest of the country and made national travel feasible. Periodically, new highway construction and changing driving habits have resulted in the obsolescence of local highways, to which the primary highway system has adapted. The former primary highways, turned over to counties and local jurisdictions, county highways, and farm-to-market roads make up the secondary highway system.
The California Department of Transportation (Caltrans) is an executive department within the U.S. state of California. Its purpose is to improve mobility across the state.
Caltrans manages the state highway system (which includes the California Freeway and Expressway System) and is actively involved with public transportation systems throughout the state.
The Washington State Department of Transportation (WSDOT or WashDOT) was established in 1905. The agency, led by a Secretary and overseen by the Governor, is a Washington governmental agency that constructs, maintains, and regulates the use of the state's transportation infrastructure. WSDOT is responsible for more than 20,000 lane-miles of roadway, nearly 3,000 vehicular bridges and 524 other structures. This infrastructure includes rail lines, state highways, state ferries (considered part of the highway system) and state airports
The Maryland highway system is a network of highways owned and maintained by the U.S. state of Maryland. In addition to the nationally-numbered Interstate Highways and U.S. Highways, the highway system consists of a network of Maryland state-numbered highways. All three types of highways together provide access to all incorporated and unincorporated areas in all 23 counties of Maryland as well as the independent city of Baltimore.
Interstate 535 (I-535) is a 2.78 miles (4.47 km) long Interstate Highway spur route of Interstate 35 in Minnesota and Wisconsin, in the United States. It is paired with U.S. Highway 53 (US 53) along its entire route.
The term crime does not, in modern times, have any simple and universally accepted definition, but one definition is that a crime, also called an offence or a criminal offence, is an act harmful not only to some individual, but also to the community or the state (a public wrong). Such acts are forbidden and punishable by law.
The Department of Transportation (DOT) is the most common name for a government agency in North America devoted to transportation. The largest is the United States Department of Transportation, which oversees interstate travel. All U.S. states, Canadian provinces, and many local agencies also have similar organizations and provide enforcement through DOT officers.
