Wellington (MBTA Station)
Wellington station is a Massachusetts Bay Transportation Authority (MBTA) Orange Line rapid transit station in Medford, Massachusetts, near the border of Everett. It is located on the Revere Beach Parkway ( Route 16), slightly east of its intersection with Route 28. Wellington functions as a park and ride with more than 1,300 spaces, and a bus hub with 10 routes terminating at the station. The Station Landing development, connected to the station by an overhead walkway, includes residential and retail buildings and additional parking. Wellington Carhouse, the primary repair and maintenance facility for the Orange Line, is located adjacent to the station. The Boston and Maine Railroad opened through the east part of what is now Medford in 1845, followed by the Medford Branch in 1847. Wellington station was soon opened near the junction; it closed with the end of passenger service on the branch in 1957. The modern station opened in September 1975 as part of the Haymarket Nort ...

Massachusetts Route 16
Route 16 is a east–west state highway in Massachusetts. It begins in the west at an intersection with Route 12 and Route 193 in Webster, just north of the Connecticut state border. It runs in a generally southwest-northeast routing through a number of Boston's suburbs and runs to the west and then north of the city before ending in Revere at an intersection with Route 1A and Route 60. Much of Route 16 east of the Newton- Wellesley town line, and especially from Cambridge eastward, is a multi-lane parkway, although it is not limited access for any significant length of road. Segments of Route 16 are also known as the Mystic Valley Parkway, the Alewife Brook Parkway, and the Revere Beach Parkway, among other names. From the western end of the Route 135 concurrency in Wellesley to Route 30 (Commonwealth Avenue) in Newton, the route serves as a part of the Boston Marathon, from the halfway point to just before Mile 18 and the hills.

Oak Grove Station
Oak Grove station is a Massachusetts Bay Transportation Authority (MBTA) intermodal transit station in the northern section of Malden, Massachusetts, just south of the Melrose border. It is the northern terminus of the rapid transit Orange Line and a stop on the Haverhill Line commuter rail service. The accessible station has a 788-space park and ride lot and is served by four MBTA bus routes. The Boston and Maine Railroad opened through Malden in 1845, and a stop at Oak Grove was added by the 1870s. It closed in 1958 amid a series of cuts. The MBTA opened the modern station in March 1977 as the northern terminus of the Haymarket North Extension of the Orange Line. It also temporarily served as the southern terminus of Haverhill Line service in 1984–85 after a bridge fire at North Station. Renovation work on the Orange Line platform, including a new emergency exit ramp, took place in 2013–14. Three new elevators were added in 2019–2022, with one existing elevator replace ...

Haverhill Line
The Haverhill Line (formerly named the Haverhill/Reading Line) is a branch of the MBTA Commuter Rail system, running north from downtown Boston, Massachusetts through the cities and towns of Malden, Melrose, Wakefield, Reading, Wilmington, Andover, North Andover, Lawrence, and Haverhill. The service operates on the Western Route of the former Boston and Maine Railroad, which extends north to Portland, Maine, though MBTA commuter rail service has not continued north of Massachusetts since 1967. History Early cutbacks Until 1959, the Boston and Maine Railroad (B&M) operated commuter service along its Western Route from Haverhill and Reading to Boston. In 1959 the section from Reading to Wilmington Junction became freight-only, and Haverhill commuter trains as well as intercity service from New Hampshire and Maine were rerouted over the Wildcat Branch and the lower Lowell Line. Salem Street stop on the Wildcat Branch opened to replace North Wilmington on the mainline. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Station (subway)
North Station is an underground MBTA subway station in Boston, Massachusetts. Served by the Massachusetts Bay Transit Authority (MBTA) Green Line and Orange Line, it is connected to the North Station surface terminal used by MBTA Commuter Rail and Amtrak. The station is fully accessible. A surface streetcar terminal at Causeway Street, adjacent to North Union Station, was built in 1898 to serve the Tremont Street subway (predecessor to the modern Green Line). An elevated station for the Main Line (predecessor to the modern Orange Line) was added in 1901 as part of the Charlestown Elevated. A second elevated station was built in 1912 as part of the Causeway Street elevated, which acted as an extension of the Tremont Street subway. The Orange Line was moved underground in 1975 for the Haymarket North Extension project. The Green Line was added in 2004, forming a "superstation". Station layout North Station is located under Haverhill Street and adjacent buildings in the block ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haymarket Station (MBTA)
Haymarket station is an underground Massachusetts Bay Transportation Authority (MBTA) rapid transit station located at Haymarket Square in Boston, Massachusetts. It is a transfer station between the Green Line and Orange Line of the MBTA subway system, as well as a terminal for MBTA bus routes serving northern and northeastern suburbs. The two lines run parallel to each other through the station, with two side platforms for the Orange Line and a single island platform for the Green Line. The station is fully accessible. The Tremont Street subway, predecessor of the modern Green Line, opened in 1898. It had a four-track streetcar station at Haymarket. The subway was also used by the Main Line, predecessor of the Green Line, from 1901 to 1908. The Main Line was rerouted into the Washington Street tunnel, with Union and Friend stations at Haymarket Square, in 1908. Union and Friend were renamed Haymarket in 1967. In 1971, the MBTA replaced the original Haymarket station with a new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Air
Sea spray are aerosol particles formed from the ocean, mostly by ejection into Earth's atmosphere by bursting bubbles at the air-sea interface. Sea spray contains both organic matter and inorganic salts that form sea salt aerosol (SSA). SSA has the ability to form cloud condensation nuclei (CCN) and remove anthropogenic aerosol pollutants from the atmosphere. Coarse sea spray has also been found to inhibit the development of lightning in storm clouds. Sea spray is directly (and indirectly, through SSA) responsible for a significant degree of the heat and moisture fluxes between the atmosphere and the ocean, affecting global climate patterns and tropical storm intensity. Sea spray also influences plant growth and species distribution in coastal ecosystems and increases corrosion of building materials in coastal areas. Generation Formation When wind, whitecaps, and breaking waves mix air into the sea surface, the air regroups to form bubbles, floats to the surface, an ...

Corrosion
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen, hydrogen or hydroxide. Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal and results in a distinctive orange colouration. Corrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term "degradation" is more common. Corrosion degrades the useful properties of materials and structures including strength, appearance and permeability to liquids and gases. Many ...

Tidal Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ha ...

Mystic River
The Mystic River is a riverU.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed April 1, 2011 in Massachusetts, in the United States. In Massachusett, means "large estuary," alluding to the tidal nature of the Mystic. The resemblance to the English word ' is a coincidence, which the colonists naturally followed. The Mystic River lies to the north of Boston and flows approximately parallel to the lower portions of the Charles River. Encompassing of watershed, the river flows from the Lower Mystic Lake and travels through the Boston-area communities of East Boston, Chelsea, Charlestown, Everett, Medford, Somerville, and Arlington. The river joins the Charles River to form inner Boston Harbor. Its watershed contains 44 lakes and ponds, the largest of which is Spot Pond in the Middlesex Fells, with an area of . Significant portions of the river's shores are within the Mystic River Reservation and are admini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston Harbor
Boston Harbor is a natural harbor and estuary of Massachusetts Bay, and is located adjacent to the city of Boston, Massachusetts. It is home to the Port of Boston, a major shipping facility in the northeastern United States. History Since its discovery to Europeans by John Smith in 1614, Boston Harbor has been an important port in American history. Early on, it was recognized by Europeans as one of the finest natural harbors in the world due to its depth and natural defense from the Atlantic as a result of the many islands that dot the harbor. It was also favored due to its access to the Charles River, Neponset River and Mystic River which made travel from the harbor deeper into Massachusetts far easier. It was the site of the Boston Tea Party, as well as almost continuous building of wharves, piers, and new filled land into the harbor until the 19th century. By 1660, almost all imports came to the greater Boston area and the New England coast through the waters of Bos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington Street Elevated
The Washington Street Elevated was an elevated segment of Boston's Massachusetts Bay Transportation Authority subway system, comprising the southern stretch of the Orange Line.
