Mount Baker Tunnel
The Mount Baker Tunnel or Mount Baker Ridge Tunnel carries Interstate 90 under the Mount Baker neighborhood of Seattle, Washington. It is actually a group of three tubes (or four --if counting the two original Mount Baker Tunnels separately) that carry eight lanes of freeway traffic, plus a separate path for bicycles and pedestrians. The original tubes are twin tunnel bores completed in 1940 and rehabilitated in 1993. The new Mount Baker Tunnel was built north of the original tunnels and opened in June 1989. The tunnel has a double-decked roadway with the bicycle/pedestrian path above the traffic lanes. The tunnel was listed on the National Register of Historic Places in 1982 (ID #82004243). The east portals of the tunnel, with murals titled ' designed by artist James FitzGerald, along with the Lacey V. Murrow Bridge, are an official City of Seattle landmark. The official length is , though the perceived length while driving is closer to because of a cut-and-cover "lid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Former West Portal Of Mt
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the adv ...

Road Tunnels On The National Register Of Historic Places
A road is a linear way for the conveyance of traffic that mostly has an road surface, improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are road hierarchy, many types of roads, including parkways, avenue (landscape), avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), median strip, medians, shoulder (road), shoulders, road verge, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organisation for Economic Co-operation and Development, Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabiliz ...

Sound Transit (ST), officially the Central Puget Sound Regional Transit Authority, is a public transit agency serving the Seattle metropolitan area in the U.S. state of Washington. It operates the Link light rail system in Seattle and Tacoma, regional Sounder commuter rail, and Sound Transit Express bus service. The agency also coordinates the regional ORCA fare card system, which is also used by local transit operators.

Redmond, Washington
Redmond is a city in King County, Washington, United States, located east of Seattle. The population was 73,256 at the 2020 census, up from 54,144 in 2010. Redmond is best known as the home of Microsoft and Nintendo of America.

Luke McRedmond filed a Homestead Act claim for land next to the Sammamish Slough on September 9, 1870, and the following year Warren Perrigo took up land adjacent to him. The rivers and streams had so many salmon that the settlement was initially named Salmonberg. More settlers came, and with the establishment of the first post office in 1881, the name of the community w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Link Light Rail
Link light rail is a light rail rapid transit system serving the Seattle metropolitan area in the U.S. state of Washington. It is managed by Sound Transit in partnership with local transit providers, and consists of two non-connected lines: the 1 Line (formerly Central Link) in King County, which travels for between Seattle and Seattle–Tacoma International Airport; and the T Line (formerly Tacoma Link) in Pierce County, which runs for under between Downtown Tacoma and Tacoma Dome Station. In , the system had a ridership of , or about per weekday as of , primarily on the 1 Line, and runs trains at frequencies of 6 to 24 minutes. The Link light rail system was originally conceived in the 1980s following several earlier proposals for a heavy rail system that were rejected by voters.

The East Link project was approved by voters in the 2008 Sound Transit 2 ballot measure, with construction costs projected at $3.7 billion. The line will use the Homer M. Hadley Memorial Bridge, one of the Interstate 90 floating bridges, which was constructed in 1989 with the intent to convert its reversible express lanes to light rail.

High-occupancy Vehicle Lane
A high-occupancy vehicle lane (also known as an HOV lane, carpool lane, diamond lane, 2+ lane, and transit lane or T2 or T3 lanes) is a restricted traffic lane reserved for the exclusive use of vehicles with a driver and one or more passengers, including carpools, vanpools, and transit buses. These restrictions may be only imposed during peak travel times or may apply at all times. According to the criteria used there are different types of lanes: temporary or permanent with concrete barriers; two-directional or reversible; and exclusive, concurrent or contraflow lanes working in peak periods. The normal minimum occupancy level is 2 or 3 occupants. Many jurisdictions exempt other vehicles, including motorcycles, charter buses, emergency and law enforcement vehicles, low-emission and other green vehicles, and/or single-occupancy vehicles paying a toll. HOV lanes are normally introduced to increase average vehicle occupancy and persons traveling with the goal of reducing traffic c ...

Cross Section Mount Baker Tunnel 3rd Tube
A cross is a geometrical figure consisting of two intersecting lines or bars, usually perpendicular to each other. The lines usually run vertically and horizontally. A cross of oblique lines, in the shape of the Latin letter X, is termed a saltire in heraldic terminology. The cross has been widely recognized as a symbol of Christianity from an early period.''Christianity: an introduction'' by Alister E. McGrath 2006 pages 321-323 However, the use of the cross as a religious symbol predates Christianity; in the ancient times it was a pagan religious symbol throughout Europe and western Asia. The effigy of a man hanging on a cross was set up in the fields to protect the crops. It often appeared in conjunction with the female-genital circle or oval, to signify the sacred marriage, as in Egyptian amule ...
