Context paragraphs:
U.S. Route 1 in the District of Columbia: With the District of Columbia, U.S. Route 1 passes between Arlington, Virginia and Mount Rainier, Maryland predominantly along surface streets.  However, it forms a few overlaps with other routes.

U.S. Route 50 in the District of Columbia: U.S. Route 50 (US 50) is a major east–west route of the U.S. Highway system, stretching just over 3000 mi from Ocean City, Maryland, on the Atlantic Ocean, to West Sacramento, California, nearly to the Pacific Ocean.  In the District of Columbia, US 50 passes between Arlington County, Virginia, and Prince George's County, Maryland, predominantly along surface streets, including a part of Constitution Avenue along the National Mall.

Race–Vine station: Race-Vine is a rapid transit passenger rail station on SEPTA's Broad Street Line.  It is located at 300 North Broad Street (PA 611) in the Center City district of Philadelphia, and serves both local and express trains.  The station is named after Vine Street, which today acts as frontage roads along Interstate 676 and nearby Race Street, although the given address is closer to westbound Vine than Race.  This stop is also used as the Pennsylvania Convention Center stop for the Broad Street Line (signs will direct passengers to the appropriate exits, although riding the Broad Street Line one stop further south to City Hall and then connecting to the Market–Frankford Line East toward Frankford and then exiting at 11th Street station will bring passengers right inside the Convention Center and The Gallery at Market East).

Liberty Bell: The Liberty Bell is an iconic symbol of American independence, located in Philadelphia, Pennsylvania.  Formerly placed in the steeple of the Pennsylvania State House (now renamed Independence Hall), the bell today is located in the Liberty Bell Center in Independence National Historical Park.  The bell was commissioned in 1752 by the Pennsylvania Provincial Assembly from the London firm of Lester and Pack (known subsequently as the Whitechapel Bell Foundry), and was cast with the lettering "Proclaim LIBERTY Throughout all the Land unto all the Inhabitants Thereof," a Biblical reference from the Book of Leviticus (25:10).  The bell first cracked when rung after its arrival in Philadelphia, and was twice recast by local workmen John Pass and John Stow, whose last names appear on the bell.  In its early years the bell was used to summon lawmakers to legislative sessions and to alert citizens about public meetings and proclamations.

Benjamin Franklin Bridge: The Benjamin Franklin Bridge – originally named the Delaware River Bridge, and now informally called the Ben Franklin Bridge – is a suspension bridge across the Delaware River connecting Philadelphia, Pennsylvania, and Camden, New Jersey.  Owned and operated by the Delaware River Port Authority, it is one of four primary vehicular bridges between Philadelphia and southern New Jersey, along with the Betsy Ross, Walt Whitman, and Tacony-Palmyra bridges.  It carries Interstate 676/U.S. Route 30.

New Jersey Route 151: Route 151 was a short, one-way pair state highway in the city of Camden, New Jersey from Dr. Martin Luther King Jr. Boulevard to County Route 537 (Federal Street) in the city.  There was also an interchange with U.S. Route 30, and the entire roadway was near Interstate 676's Interchange 5A.  Route 151 ran along South Tenth Street for eastbound traffic and South Eleventh Street for westbound traffic west of Mount Ephraim Avenue.  From there, South Tenth was known as Flanders Avenue and South Eleventh was known as Memorial Avenue.  At U.S. Route 30, the route continued bi-directionally as Flanders Avenue until its end at County Route 537.

Interstate 78 in New Jersey: Interstate 78 (I-78) is an east–west route stretching from Union Township, Lebanon County, Pennsylvania to New York City.  In New Jersey, I-78 is called the Phillipsburg–Newark Expressway and the Newark Bay Extension of the New Jersey Turnpike.  The highway runs for 67.83 mi in the northern part of the state of New Jersey from the Interstate 78 Toll Bridge over the Delaware River at the Pennsylvania state line in Phillipsburg, Warren County east to the Holland Tunnel under the Hudson River at the New York state line in Jersey City, Hudson County.  The Phillipsburg-Newark Expressway portion of I-78, formally called the Lightning Division Memorial Highway, runs from the Phillipsburg area east across rural areas of western New Jersey before entering suburban areas in Somerset County.  The road crosses the Watchung Mountains, widening into a local-express lane configuration at Route 24 as it continues through urban areas to Newark.  Here, I-78 intersects the mainline of the New Jersey Turnpike (I-95) and becomes the Newark Bay Extension, crossing the Newark Bay Bridge and continuing to Jersey City.  The route, along with Route 139, follows a one-way pair of surface streets to the Holland Tunnel.

Melton (cloth): Melton cloth is traditionally made of wool and is woven in a twill form.  It is thick, due to having been well fulled, which gives it a felt-like smooth surface.  It is napped and very closely sheared.  Meltons are similar to Mackinaw cloth.  It is a very solid cloth in which the twill weave pattern is completely concealed due to the finishing processes.  Because of its dense, quasi-felted texture it frays minimally or not at all.  It is hard wearing and wind and weather resistant.  Its main use is for heavy outer garments and coats and for blankets.  In lighter weights melton cloth is traditionally used for lining the underside of jacket collars.  It was developed in the Leicestershire town of Melton Mowbray, from which it derives its name.  This town is the traditional centre of English fox-hunting, and black and scarlet hunting coats are traditionally made from melton cloth, due to its weatherproof qualities.  In England not only is melton used for the scarlet hunting coat, an iconic symbol of the upper-class elite, but it is also used in black for the donkey jacket, an iconic symbol of the working class labouring man.  Both uses rely on its weatherproof qualities.

Interstate 676: Interstate 676 (abbreviated I-676) is an Interstate Highway that serves as a major thoroughfare through Center City Philadelphia, where it is known as the Vine Street Expressway, and Camden, New Jersey, where it is known as the northern segment of the North–South Freeway, as well as the Martin Luther King Jr. Memorial Highway.  Its western terminus is at I-76 in Philadelphia near the Philadelphia Museum of Art and Fairmount Park.  From there it heads east and is then routed on surface streets near Franklin Square and Independence Mall, home of the Liberty Bell, before crossing the Ben Franklin Bridge.  On the New Jersey side of the bridge, the highway heads south to its southern terminus at I-76 in Gloucester City near the Walt Whitman Bridge.  Between the western terminus and downtown Camden, I-676 is concurrent with U.S. Route 30 (US 30).

Waterfront South: Waterfront South is a neighborhood in Camden, New Jersey.  Located in the southern part of the city, below Central Waterfront, between the Delaware River and Interstate 676, the neighborhood has a population of 1,781.
