Parkway

Parkway is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Parkway rather than just read about it. In short: A parkway is a landscaped thoroughfare. The term is particularly used for a roadway in a park or connecting to a park from which trucks and other heavy vehicles are excluded.

Key takeaways

  • Parkway belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Parkway to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Parkway from memory before moving on to harder problems.

Reference excerpt

A parkway is a landscaped thoroughfare. The term is particularly used for a roadway in a park or connecting to a park from which trucks and other heavy vehicles are excluded. Over the years, many different types of roads have been labeled parkways. The term may be used to describe city streets as narrow as two lanes with a landscaped median, wide landscaped setbacks, or both. The term has also been applied to scenic highways and to limited-access roads more generally. Many parkways originally intended for scenic, recreational driving have evolved into major urban and commuter routes.

United States

Scenic roads The first parkways in the United States were developed during the late 19th century by landscape architects Frederick Law Olmsted and Calvert Vaux as roads that separated pedestrians, bicyclists, equestrians, and horse carriages, such as Eastern Parkway, which is credited as the world's first parkway, and Ocean Parkway in the New York City borough of Brooklyn. The term "parkway" to define this type of road was coined by Calvert Vaux and Frederick Law Olmsted in their proposal to link city and suburban parks with "pleasure roads".In Buffalo, New York, Olmsted and Vaux used parkways with landscaped medians and setbacks to create the first interconnected park and parkway system in the United States. Bidwell Parkway and Chapin Parkway are 200 foot wide city streets with only one lane for cars in each direction and broad landscaped medians that provide a pleasant, shaded route to the park and serve as mini-parks within the neighborhood. The Rhode Island Metropolitan Park Commission developed several parkways in the Providence area. Other parkways, such as Park Presidio Boulevard in San Francisco, California, were designed to serve larger volumes of traffic. During the early 20th century, the meaning of the word was expanded to include limited-access highways designed for recreational driving of automobiles, with landscaping. These parkways originally provided scenic routes without very slow or commercial vehicles, at grade intersections, or pedestrian traffic. Examples are the Merritt Parkway in Connecticut and the Vanderbilt Motor Parkway in New York. But their success led to more development, expanding a city's boundaries, eventually limiting the parkway's recreational driving use. The Arroyo Seco Parkway between Downtown Los Angeles and Pasadena, California, is an example of lost pastoral aesthetics. It and others have become major commuting routes, while retaining the name "parkway".

Early high speed roads

In New York City, construction on the Long Island Motor Parkway (Vanderbilt Parkway) began in 1906 and planning for the Bronx River Parkway in 1907. In the 1920s, the New York City Metropolitan Area's parkway system grew under the direction of Robert Moses, the president of the New York State Council of Parks and Long Island State Park Commission, who used parkways to provide access to newly created state parks, especially for city dwellers. As Commissioner of New York City Parks under Mayor LaGuardia, he extended the parkways to the heart of the city, creating and linking its parks to the greater metropolitan systems. Most of the New York metropolitan parkways were designed by Gilmore Clark. The famed "Gateway to New England" Merritt Parkway in Connecticut was designed in the 1930s as a pleasurable alternative for affluent locals to the congested Boston Post Road, running through forest with each bridge designed uniquely to enhance the scenery. Another example is the Sprain Brook Parkway from lower-Westchester to connect to the Taconic State Parkway to Chatham, New York. Landscape architect George Kessler designed extensive parkway systems for Kansas City, Missouri; Memphis, Tennessee; Indianapolis; and other cities at the beginning of the 20th century.

New Deal roads

In the 1930s, as part of the New Deal, the U.S. federal government constructed National Parkways designed for recreational driving and to commemorate historic trails and routes. These divided four-lane parkways have lower speed limits and are maintained by the National Park Service. An example is the Civilian Conservation Corps (CCC) built Blue Ridge Parkway in the Appalachian Mountains of North Carolina and Virginia. Others are Skyline Drive in Virginia; the Natchez Trace Parkway in Mississippi, Alabama, and Tennessee; and the Colonial Parkway in eastern Virginia's Historic Triangle area. The George Washington Memorial Parkway and the Clara Barton Parkway, running along the Potomac River near Washington, D.C., and Alexandria, Virginia, were also constructed during this era.

Post-war parkways

In Kentucky the term "parkway" designates a freeway in the Kentucky Parkway system, with nine built in the 1960s and 1970s. They were toll roads until the construction bonds were repaid; the last of these roads to charge tolls became freeways in 2006. The Arroyo Seco Parkway from Pasadena to Los Angeles, built in 1940, was the first segment of the vast Southern California freeway system. It became part of State Route 110 and was renamed the Pasadena Freeway. A 2010 restoration of the freeway brought the Arroyo Seco Parkway designation back.

Worked examples

Example 1 — a first encounter with Parkway

Start with the simplest possible case. Write down what Parkway claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Parkway before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Parkway ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Parkway

In research
Parkway appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Parkway in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Parkway is common in secondary-school and first-year university syllabi. It links to neighbouring topics Environmental design, Landscape, Limited-access roads, so understanding it makes those chapters shorter.
In everyday life
Look for Parkway outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Parkway matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Parkway?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
