What's the Difference Between a Street, a Road, and an Avenue?

Depending on where you live, your address will end in a different designation. You might live on 10th Street, or Meadow Lane, or Red Fox Road. Maybe those throughways intersect a road with a name like Washington Avenue or Park Place. Why the difference? There’s actually a method to the road-naming madness that goes beyond just the whims of urban designers.

Just like there are defined factors that distinguish a highway from a regular city street, there are characteristics that make streets, roads, and avenues distinct from one another. The difference between names like C Street and Avenue B comes down to variables like the size of the path, what surrounds it, and how it intersects with other roads.

A plain old “road,” for instance, is a general term for any throughway that connects two points. Like a square is also a rectangle, streets and avenues are types of roads.

“Streets” are public roads that have buildings on both sides. They’re often perpendicular to “avenues,” which historically were grander and wider. These days, the difference tends to be directional.

In Denver, for instance, naming conventions dictate that Streets run north-south and avenues run east-west. In Manhattan, it’s the opposite, with “Avenues” running north-south and streets running east-west. This isn’t always the case, though: in Washington, D.C., avenues run diagonal to the street grid.

Oddly enough, avenues and streets can be combined, too. In a naming convention particular to Tucson, Arizona, some roads are “Stravenues,” which run diagonal to the normal north-south/east-west grid. (The U.S. Postal Service recognizes these by the abbreviation “Stra.”)

There are many other kinds of street names, of course. "Boulevards," designed to funnel high-speed traffic away from residential and commercial streets, are even grander than avenues, with trees on either side and a sizable median. Then there are the smaller roads, with names that might feel familiar to anyone who’s driven around a suburban housing tract. A “Way” is a smaller side street that splits off from a road. A “Place” has a dead end, as does a “court,” which usually ends in a cul-de-sac. A “Lane” is narrow, and is usually located in a more remote, rural place. A "Drive" tends to wind around a natural landmark, like a mountain or a lake.

To get a better sense of the visual differences, a video from Vox handily illustrates these principles:

Now, you can look at an address and know plenty about the street without even seeing it.

What’s the Difference Between Prison and Jail?

Many people use the terms jail and prison interchangeably, and while both terms refer to areas where people are held, there's a substantial difference between the two methods of incarceration. Where a person who is accused of a crime is held, and for how long, is a factor in determining the difference between the two—and whether a person is held in a jail or a prison is largely determined by the severity of the crime they have committed.

A jail (or, for our British friends, a gaol) refers to a small, temporary holding facility—run by local governments and supervised by county sheriff departments—that is designed to detain recently arrested people who have committed a minor offense or misdemeanor. A person can also be held in jail for an extended period of time if the sentence for their offense is less than a year. There are currently 3163 local jail facilities in the United States.

A jail is different from the similarly temporary “lockup”—sort of like “pre-jail”—which is located in local police departments and holds offenders unable to post bail, people arrested for public drunkenness who are kept until they are sober, or, most importantly, offenders waiting to be processed into the jail system.

A prison, on the other hand, is usually a large state- or federal-run facility meant to house people convicted of a serious crime or felony, and whose sentences for those crimes surpass 365 days. A prison could also be called a “penitentiary,” among other names.

To be put in a state prison, a person must be convicted of breaking a state law. To be put in a federal prison, a person must be convicted of breaking federal law. Basic amenities in a prison are more extensive than in a jail because, obviously, an inmate is likely to spend more than a year of his or her life confined inside a prison. As of 2012, there were 4575 operating prisons in the U.S.—the most in the world. The country with the second highest number of operating prisons is Russia, which has just 1029 facilities.

What Do Morticians Do With the Blood They Take Out of Dead Bodies?

Zoe-Anne Barcellos:

The blood goes down the sink drain, into the sewer system.

I am not a mortician, but I work for a medical examiner/coroner. During an autopsy, most blood is drained from the decedent. This is not on purpose, but a result of gravity. Later a mortician may or may not embalm, depending on the wishes of the family.

Autopsies are done on a table that has a drain at one end; this drain is placed over a sink—a regular sink, with a garbage disposal in it. The blood and bodily fluids just drain down the table, into the sink, and down the drain. This goes into the sewer, like every other sink and toilet, and (usually) goes to a water treatment plant.

You may be thinking that this is biohazardous waste and needs to be treated differently. [If] we can’t put oil, or chemicals (like formalin) down the drains due to regulations, why is blood not treated similarly? I would assume because it is effectively handled by the water treatment plants. If it wasn’t, I am sure the regulations would be changed.

Now any items that are soiled with blood—those cannot be thrown away in the regular trash. Most clothing worn by the decedent is either retained for evidence or released with the decedent to the funeral home—even if they were bloody.

But any gauze, medical tubing, papers, etc. that have blood or bodily fluids on them must be thrown away into a biohazardous trash. These are lined with bright red trash liners, and these are placed in a specially marked box and taped closed. These boxes are stacked up in the garage until they are picked up by a specialty garbage company. I am not sure, but I am pretty sure they are incinerated.

Additionally anything sharp or pointy—like needles, scalpels, etc.—must go into a rigid “sharps” container. When they are 2/3 full we just toss these into one of the biotrash containers.

The biotrash is treated differently, as, if it went to a landfill, then the blood (and therefore the bloodborne pathogens like Hepatitis and HIV) could be exposed to people or animals. Rain could wash it into untreated water systems.
