Mount Hood Freeway
The Mount Hood Freeway is a partially constructed but never to be completed freeway alignment of U.S. Route 26 and Interstate 80N (now Interstate 84), which would have run through southeast Portland, Oregon. Related projects would have continued the route through the neighboring suburb of Gresham, out to the city of Sandy. The original plans for the freeway were presented by the Oregon State Highway Department as part of a 1955 report that proposed 14 new highways in the Portland metropolitan area. (Urban planner Robert Moses drafted Portland's original postwar infrastructure plan.) The proposed route was to run parallel to the existing alignment of US 26 on Powell Boulevard, and would have required the destruction of 1,750 long-standing Portland homes and one percent of the Portland housing stock. Plans for the freeway triggered a revolt in Portland in the late 1960s and early 1970s, leading to its eventual cancellation. Plans for other proposed freeways in Portland were ...

Interstate 205 In Oregon
The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, is a network of controlled-access highways that forms part of the National Highway System in the United States. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico. The U.S. federal government first funded roadways through the Federal Aid Road Act of 1916, and began an effort to construct a national road grid with the passage of the Federal Aid Highway Act of 1921. In 1926, the United States Numbered Highway System was established, creating the first national road numbering system for cross-country travel. The roads were still state-funded and maintained, however, and there was little in the way of national standards for road design. U.S. Highways could be anything from a two-lane country road to a major multi-lane freeway. After Dwight D. Eisenhower became president in 1953, his administrati ...

Bus Rapid Transit
Bus rapid transit (BRT), also called a busway or transitway, is a bus-based public transport system designed to have much more capacity, reliability and other quality features than a conventional bus system. Typically, a BRT system includes roadways that are dedicated to buses, and gives priority to buses at intersections where buses may interact with other traffic; alongside design features to reduce delays caused by passengers boarding or leaving buses, or paying fares. BRT aims to combine the capacity and speed of a light rail or metro system (LRT, HRT) with the flexibility, lower cost and simplicity of a bus system. The world's first BRT system was the Busway in Runcorn New Town, England, which entered service in 1971. , a total of 166 cities in six continents have implemented BRT systems, accounting for of BRT lanes and about 32.2 million passengers every day. The majority of these are in Latin America, where about 19.6 million passengers ride daily, and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Induced Demand
In economics, induced demand – related to latent demand and generated demandSchneider, Benjamin (September 6, 2018"CityLab University: Induced Demand"''CityLab'' – is the phenomenon whereby an increase in supply results in a decline in price and an increase in consumption. In other words, as a good or service becomes more readily available and mass produced, its price goes down and consumers are more likely to buy it, meaning that demand subsequently increases. This is consistent with the economic theory of supply and demand. In transportation planning, induced demand, also called "induced traffic" or consumption of road capacity, has become important in the debate over the expansion of transportation systems, and is often used as an argument against increasing roadway traffic capacity as a cure for congestion. Induced traffic may be a contributing factor to urban sprawl. City planner Jeff Speck has called induced demand "the great intellectual black hole in city plan ...

Interstate 405 (Oregon)
Interstate 405 (I-405), also known as the Stadium Freeway No. 61, is a short north–south Interstate Highway in Portland, Oregon. It forms a loop that travels around the west side of Downtown Portland, between two junctions with I-5 on the Willamette River near the Marquam Bridge to the south and Fremont Bridge to the north. The Stadium Freeway was envisioned in the 1940s and 1950s by the state government and was added to the Interstate Highway system in 1958. Construction began in 1963, utilizing a trench with extensive landscaping and frequent overpasses, and was the most expensive freeway project in state history at a cost of $121 million. Hundreds of buildings were demolished to make way for the freeway, which displaced approximately 1,100 households. The southernmost section of I-405 opened on October 26, 1965, and was followed by extensions in 1966 and 1969. The final section, including the Fremont Bridge, opened in November 1973.

Ross Island Bridge
The Ross Island Bridge is a cantilever truss bridge that spans the Willamette River in Portland, Oregon. It carries U.S. Route 26 (Mount Hood Highway) across the river between southwest and southeast Portland. The bridge opened in 1926 and was designed by Gustav Lindenthal and honors Oregon pioneer Sherry Ross. It is named for its proximity to Ross Island. Although it looks like a deck arch bridge, it is a cantilever deck truss bridge, a rare type in Oregon. History and description The bridge was part of the unprecedented period of bridge building in Portland during the 1920s. It was opened on December 21, 1926, and cost $2 million to construct. The bridge was designed by a famous engineer named Gustav Lindenthal. The bridge is named for its location close to Ross Island, an island in the Willamette River which measures about one-and-a-half by one mile. The bridge is about 800 feet (250 m) north of the island and does not connect with, nor does it provide access to, Ross Isl ...
