Washington State Route 17
State Route 17 (SR 17) is a state highway serving the Columbia Plateau in the central region of the U.S. state of Washington. The highway travels through mostly rural areas of Franklin. Adams, Grant, Douglas, and Okanogan counties and is designated as part of the National Highway System between Mesa and Moses Lake and as the Coulee Corridor Scenic Byway between Othello and Coulee City for passing through the Grand Coulee. SR 17 begins in Mesa at an interchange with U.S. Route 395 (US 395) and travels north and intersects SR 26 near Othello before entering Moses Lake, where the highway intersects Interstate 90 (I-90) and travels as a partial expressway. SR 17 continues north, intersecting SR 28 in Soap Lake, through the Grand Coulee to a short concurrency with US 2 west of Coulee City. The highway turns northwest and crosses the Columbia River on the Columbia River Bridge at Bridgeport before ending at US 97 in Brew ...

Columbia Plateau
The Columbia Plateau is a geologic and geographic region that lies across parts of the U.S. states of Washington, Oregon, and Idaho. It is a wide flood basalt plateau between the Cascade Range and the Rocky Mountains, cut through by the Columbia River. Geology During late Miocene and early Pliocene times, a flood basalt engulfed about of the Pacific Northwest, forming a large igneous province. Over a period of perhaps 10 to 15 million years, lava flow after lava flow poured out, ultimately accumulating to a thickness of more than 6,000 feet (1.8 km). As the molten rock came to the surface, the Earth's crust gradually sank into the space left by the rising lava. The Columbia River Basalt Group consists of seven formations: The Steens Basalt, Imnaha Basalt, Grande Ronde Basalt, Picture Gorge Basalt, Prineville Basalt, Wanapum Basalt, and Saddle Mountains Basalt. Many of these formations are subdivided into formal and informal members and flows. The subsidence of the crust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1964 Highway Renumbering (Washington)
The 1964 state highway renumbering was a reorganization of state highways in the U.S. state of Washington. The new system, based on sign routes (SR, later changed to state routes), replaced the primary and secondary highway system implemented in 1937. It was first signed in January 1964 and codified into the Revised Code of Washington in 1970. History The former numbering system of primary and secondary state highways, using lettered suffixes and unnamed branches, created confusion for motorists as the system expanded. The system also ignored, or conflicted with, the federal highway system and the then-developing Interstate Highway System. The state highway department originally planned for a major highway renumbering in 1957, expanding on the existing primary and secondary system with numbers as high as 59, but serious consideration of a full-scale renumbering began in 1962. It had the specific goal of replacing letter suffixes with two- and three-digit numbers, which wou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colville Indian Reservation
The Colville Indian Reservation is an Indian reservation in the northwest United States, in north central Washington, inhabited and managed by the Confederated Tribes of the Colville Reservation, which is federally recognized. Established in 1872, the reservation currently consists of , located primarily in the southeastern section of Okanogan County and the southern half of Ferry County. It also includes other pieces of trust land in eastern Washington, including in Chelan County, just to the northwest of the city of Chelan. The reservation's name is adapted from that of Fort Colville, which was named by British colonists for Andrew Colville, a London governor of the Hudson's Bay Company.

Bridgeport, Washington
Bridgeport is a city in Douglas County, Washington. It is part of the Wenatchee−East Wenatchee Metropolitan Statistical Area. Bridgeport's population was 2,409 at the 2010 census. Bridgeport is located near the Chief Joseph Dam. History The area that is now Bridgeport was settled in the late 19th century and originally named Westfield. Some of the earliest settlers in the area were Chinese miners extracting gold from the banks of the Columbia River. Developers purchased the town in 1892 and renamed it Bridgeport after where they had come from, Bridgeport, Connecticut. The city of Bridgeport was officially incorporated on March 21, 1910. The biggest economic boom to come to the city came from the building of the massive Foster Creek Dam, later renamed the Chief Joseph Dam, just upstream from the city limits. Geography Bridgeport is located at (48.006238, -119.671540). According to the United States Census Bureau, the city has a total area of , all of it land. Bridgeport has ...

Columbia River Bridge (Bridgeport, Washington)
The Columbia River Bridge, also known as the Bridgeport Bridge, at Bridgeport, Washington, was built to span the Columbia River in 1950. Composed of three spans, the bridge is a steel continuous riveted deck truss carrying Washington State Route 17 on a roadway and two sidewalks. The center portion of the bridge spans , flanked by end spans. The north approach span and the south approach span are supported by steel plate girders. The bridge played a significant role in the construction of the Chief Joseph Dam just upstream, as no bridge crossing had previously existed in the area. Construction on the dam started in 1945 and was completed, apart from the powerplant, in 1955. The bridge was designed and built by the U.S. Army Corps of Engineers as part of the Chief Joseph Dam project, and is significant for its association with the project and as a major crossing of the Columbia. The bridge was placed on the National Register of Historic Places The National Register of Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbia River
The Columbia River (Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the U.S. state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific. The Columbia has the 36th greatest discharge of any river in the world. The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. They have been used for transportation since a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concurrency (road)
A concurrency in a road network is an instance of one physical roadway bearing two or more different route numbers. When two roadways share the same right-of-way, it is sometimes called a common section or commons. Other terminology for a concurrency includes overlap, coincidence, duplex (two concurrent routes), triplex (three concurrent routes), multiplex (any number of concurrent routes), dual routing or triple routing. Concurrent numbering can become very common in jurisdictions that allow it. Where multiple routes must pass between a single mountain crossing or over a bridge, or through a major city, it is often economically and practically advantageous for them all to be accommodated on a single physical roadway. In some jurisdictions, however, concurrent numbering is avoided by posting only one route number on highway signs; these routes disappear at the start of the concurrency and reappear when it ends. However, any route that becomes unsigned in the middle of the concurren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington State Route 28
State Route 28 (SR 28) is a state highway in the U.S. state of Washington. It travels across the central region of the state, passing through Douglas, Grant, and Lincoln counties. The highway begins at an intersection with U.S. Route 2 (US 2) and US 97 near East Wenatchee and travels east through Quincy, Ephrata, and Odessa before terminating at US 2 in Davenport. The route follows the Columbia River and the BNSF Railway's Columbia River Subdivision through the largely rural area between Wenatchee and Davenport. The Quincy–Davenport route was historically part of the North Central Highway, established in 1915 as part of the early state highway system along a section of the Great Northern Railway. The highway was numbered as State Road 7 in 1923 and connected to Wenatchee via State Road 10, also known as the Chelan and Okanogan Highway. The two highways retained their numbers under the primary numbering system in 1937 and were combine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate 90 In Washington
Interstate 90 (I-90), designated as the American Veterans Memorial Highway, is a transcontinental Interstate Highway that runs from Seattle, Washington, to Boston, Massachusetts. It crosses Washington state from west to east, traveling from Seattle across the Cascade Mountains and into Eastern Washington, reaching the Idaho state line east of Spokane. I-90 intersects several of the state's other major highways, including I-5 in Seattle, I-82 and U.S. Route 97 (US 97) near Ellensburg, and US 395 and US 2 in Spokane. I-90 is the only Interstate to cross the state from west to east, and the only one to connect the state's two largest cities, Seattle and Spokane. It incorporates two of the longest floating bridges in the world, the Lacey V. Murrow Memorial Bridge and the Homer M.

Washington State Route 26
State Route 26 (SR 26) is a state highway in central Washington in the United States. It travels east–west for from Interstate 90 (I-90) near Vantage to U.S. Route 195 (US 195) in Colfax. The highway intersects several major north–south highways, including SR 24, SR 17, US 395, and SR 261 before ending in Colfax. The route serves as a connector between Vantage, Royal City, Othello, Washtucna, La Crosse, and Colfax. The easternmost section of SR 26, between Dusty and Colfax was formerly part of the Inland Empire Highway and US 295 for most of the early 20th century. The rest of modern SR 26 was added to the state highway system in 1937 and 1951 as Secondary State Highway 11B (SSH 11B) from Washtucna to Dusty and SSH 7C from Vantage to Washtucna, respectively. The two highways were combined to form SR 26 in the 1964 state highway renumbering, but several sections of the highway were not complet ...

Grand Coulee
Grand Coulee is an ancient river bed in the U.S. state of Washington. This National Natural Landmark stretches for about 60 miles (100 km) southwest from Grand Coulee Dam to Soap Lake, being bisected by Dry Falls into the Upper and Lower Grand Coulee. Geological history Grand Coulee is a large coulee on the Columbia River Plateau. This area has underlying granite bedrock, formed deep in the Earth's crust 40 to 60 million years ago. The land periodically uplifted and subsided over millions of years giving rise to some small mountains and, eventually, an inland sea. From about 10 to 18 million years ago, a series of volcanic eruptions from the Grand Ronde Rift near the Idaho/Oregon/Washington/Montana border began to fill the inland sea with lava. In some places the volcanic basalt is thick. In other areas granite from the earlier mountains is still exposed. Starting about two million years ago, during the Pleistocene epoch, glaciation took place in the area. Large parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
