Context paragraphs:
West Side (Manhattan): The West Side of Manhattan refers to the side of Manhattan Island which abuts the Hudson River and faces New Jersey.  Fifth Avenue, Central Park, and lower Broadway separate it from the East Side.  The major neighborhoods on the West Side are (from north to south) West Harlem, Morningside Heights, Manhattan Valley, Upper West Side, Hell's Kitchen, Chelsea, West Village, SoHo, and Tribeca.  The 8th Avenue and West Side subway lines connect all parts of the West Side.  The main north-south roads servicing the West Side are the Henry Hudson Parkway in the north, and the West Side Highway in the south.  The Hudson River Greenway separates them from the west shore of the island.

Florida State Road 925: State Road 925 (SR 925) is a pair of north-south roads in Miami, Florida connecting westbound SR 968 with the I-95 exits on Northwest 8th Street.  The northbound road is known locally as Northwest 3rd Avenue and runs 0.565 mi .  The southbound road is known as Northwest 3rd Court and runs 0.506 mi .  Both roads run parallel to Interstate 95 on opposite sides.  The SR 925 designation was created in 2014 as part of a jurisdictional swap over various roadways between the Florida Department of Transportation (FDOT) and the City of Miami.

A66 road: The A66 is a major road in Northern England, which in part follows the course of the Roman road from Scotch Corner to Penrith.  It runs from east of Middlesbrough in the ceremonial county of North Yorkshire to Workington in Cumbria.  It is anomalously numbered since west of Penrith it trespasses into numbering zone 5; this is because it originally terminated at the A6 in Penrith but was extended further west in order to create one continuous east–west route.  Most of what is now the A66 west of Penrith was originally A594 – only a small stub of this road numbering remains, from Maryport to Cockermouth.

Pekin Street Historic District: The Pekin Street Historic District is a residential historic district bounded by Pekin and Candace Streets, Douglas and Chalkstone Avenues in Providence, Rhode Island.  It is a well-preserved densely built neighborhood of working class housing, built almost entirely between 1870 and 1910.  Most of the structures are either two or three-family units, with two-families predominating among the older buildings and triple-deckers among the later ones.  The buildings are generally set on narrow lots with small yards.  The district's main north-south roads are Pekin and Candace Streets, which are joined by a number of cross streets.

Inca road system: The Inca road system was the most extensive and advanced transportation system in pre-Columbian South America.  It was about 24800 mi long.  The construction of the roads required a large expenditure of time and effort, and the quality of that construction is borne out by the fact that it is still in quite good condition after over 400 years of use.  The network was based on two north-south roads with numerous branches.  The best known portion of the road system is the Inca Trail to Machu Picchu.  Part of the road network was built by cultures that precede the Inca Empire, notably the Wari culture.  During the Spanish colonial era, parts of the road system were given the status of "Camino Real".  In 2014 the road system became a UNESCO World Heritage Site.

Fifth and Main Historic District: The Fifth and Main Historic District is a collection of adjoining structures and national historic district located on the northeast corner of the intersection of Main and Fifth streets in Joplin, Jasper County, Missouri, United States.  This historic district consists of three early 20th century structures: the Christman Building, the Christman Building Annex and the Paramount Building.  The Fifth and Main Historic District was added to the National Register of Historic Places in 2006.  In 2008, it was encompassed by the Joplin Downtown Historic District.

Decumano Superiore, Naples: The Decumano or Decumanus Superiore was one of the three main North-South roads (Decumani) in the Ancient Roman city of Naples.

A6 road (England): The A6 is one of the main historic north-south roads in England.  It currently runs from Luton in Bedfordshire to Carlisle in Cumbria, although it formerly started at a junction with the A1 at Barnet.  It is the fourth longest numbered road in Britain, behind only the A1, A38 and A30.

Hadlyme North Historic District: The Hadlyme North Historic District is an 81 acre historic district located in the southwest corner of the town of East Haddam, Connecticut (just north of the town line with Lyme).  It represents the core of the village of Hadlyme, which straddles the town line, and consists primarily of two north-south roads, Town Street (Route 82 and Old Town Street).  The district includes 39 contributing buildings and 12 non-contributing buildings, with examples of Colonial, Mid 19th Century Revival, and "Postmedieval English" architecture.  The district also includes a cemetery and a rock-walled mill pond.  It was listed on the National Register of Historic Places in 1988.

Ouellette Avenue: Ouellette Avenue (most commonly pronounced Oh-Let, pronounced by French-speakers as 'Wellette') is one of the main North-South Roads in Windsor, Ontario, and acts as its Main Street.
