10 Things You Might Not Know About the U.S. Interstate System

Inspired by the network of high-speed roads he saw in Germany during World War II, Dwight D. Eisenhower championed the passing of the Federal-Aid Highway Act of 1956. The law funded the first 41,000 miles of paved glory that made up the early U.S. interstate system, which now boasts 46,876 miles and runs through all 50 states. (Yes, even Alaska and Hawaii.) Prepare for your next cross-country (or cross-town) road trip with the following facts.

1. IT TOOK 17 YEARS TO CREATE AND FUND THE IDEA OF THE INTERSTATE.

Two members of the U.S. Bureau of Public Roads presented a report to Congress in 1939 that detailed the need for a non-tolled road system in the U.S. The Federal Highway Act of 1944 allowed for development of a 40,000 mile National System of Interstate Highways, but it didn’t provide any method of funding, so it went nowhere. It wasn’t until the act of 1956 that funding was finally allocated to its construction.

2. PEOPLE FIRST LOVED, THEN HATED IT. 

When the Interstate Highway Act was passed, most Americans thought it was a good idea. But when construction started and people, especially in urban areas, were displaced and communities cut in half, some started to revolt. In the 1960s, activists stopped construction on highways in New York, Baltimore, Washington, D.C., and New Orleans, which resulted in several urban interstates becoming roads to nowhere.

3. EVERY STATE OWNS ITS PORTION (INCLUDING THE POTHOLES) …

This means the state is responsible for enforcing traffic laws and maintaining the section of highway in its borders. Currently, the “largest pothole in the country” award has been claimed by this section of I-75 outside Detroit. 

4. … EXCEPT FOR ONE (FORMER) BRIDGE.

The Woodrow Wilson Memorial Bridge (I-95/495) that crossed the Potomac River into Washington, D.C. used to be the only part of the interstate system owned by the Federal Highway Administration. But issues over it being too small led to the creation of a new, bigger, taller bridge. As for the old one? It was destroyed, in part by people who won a contest for having “the toughest daily drive.”

5. THE STATES SET THE SPEED LIMITS.

However, in the early 1970s, all 50 states set their speed limits to 55 mph. A clause in the Emergency Highway Energy Conservation Act signed into law by Richard Nixon dictated that if a state did not set its highway speed limit to 55 mph, that state would lose its federal highway funding. 

6. THE SIGNS ARE TRADEMARKED.

The red, white, and blue shields used to designate interstate numbers are trademarked by the American Association of State Highway Officials. The original design for the shield was drawn by senior traffic engineer Richard Oliver of Texas and selected out of 100 entries in a national design competition in 1957. 

7. INTERSTATES AND HIGHWAYS WITH THE SAME NUMBER CANNOT RUN THROUGH THE SAME STATE.

The numbering system used for interstates is intended to be the mirror opposite of the U.S. highway system, so drivers won't be confused about whether to take Highway 70 or Interstate 70. For example, I-10 runs through southern states east-west (as all major even-numbered interstates do; odd-numbered interstates run north-south), while Highway 10 runs through northern states. Because I-50 would run through the same states as Route 50, the number will never be used. 

8. I-99 DOESN'T FOLLOW THIS SYSTEM, BUT THAT'S NOT THE FEDERAL HIGHWAY ADMINISTRATION'S FAULT.

According to the Federal Highway Administration's numbering system, Pennsylvania's former US 220 should have been named something like I-876 or I-280. But Representative Bob Shuster wanted a catchier moniker for it. According to The New York Times, as a child he was fond of the No. 99 streetcar, which he used as his inspiration for the road's tag. 

9. THE INTERSTATE IS PART OF THE U.S.' ATOMIC ATTACK PLAN. 

A major concern during Eisenhower’s presidency was what the country would do in the event of a nuclear attack. One of the justifications for the building of the interstate system was its ability to evacuate citizens of major cities if necessary. 

10. THERE ARE NO DESIGN RULES DICTATING THE SHAPE OF ROADS.

A major myth of the interstate system is that one out of every five miles is straight so an airplane can land. While this has happened, there are no rules or regulations that require such a design. Also, there are no requirements for curves to be designed into a highway to keep drivers awake. However, the Federal Highway Administration does admit that this is a perk of winding roads.

7 People Killed by Musical Instruments

We’re used to taking it figuratively. One “slays” on guitar, is a “killer” pianist, or wants to “die” listening to a miraculous piece of music. History, though, is surprisingly rich with examples of people actually killed by musical instruments. Some were bludgeoned and some crushed; others were snuffed out by the sheer effort of performing or while an instrument was devilishly played to cover up the crime. Below are seven people who met their end thanks to a musical instrument.

1. Elizabeth Jackson // Struck with a Flute

David Mills was practicing his flute the night of March 25, 1751, when he got into a heated argument with fellow servant Elizabeth Jackson. A woman “given to passion,” she threw a candlestick at Mills after he said something rude. He retaliated by striking her left temple with his flute before the porter and the footman pulled them apart. Jackson lived for another four hours, able to walk but not make sensible speech. Her fellow servants decided to bleed her, a sadly ineffective treatment for skull fractures. “Her s[k]ull was remarkably thin,” the surgeon testified at Mills’s trial.

2. Louis Vierne // Exhausted by an Organ Recital

Reputed to be the king of instruments, the organ requires a performer with an athletic endurance—more than 67-year-old Louis Vierne had to give during a recital at Notre Dame cathedral on June 2, 1937. He collapsed (likely of a heart attack) after playing the last chord of a piece. With a Gallic appreciation for tragedy, one concertgoer noted the piece “bears a title which, given the circumstance, seems like fate and takes on an oddly disturbing meaning: ‘Tombstone for a dead child’!” As Vierne’s lifeless feet fell upon the pedalboard “a low whimper was heard from the admirable instrument, which seemed to weep for its master,” the concertgoer wrote.

3. James “Jimmy the Beard” Ferrozzo // Crushed by a Piano

Getting crushed by a piano is usually the stuff of cartoons, but what happened to James Ferrozzo is somehow even stranger than a cartoon. “A nude, screaming dancer found trapped under a man’s crushed body on a trick piano pinned against a nightclub ceiling was too drunk to remember how she got there,” the AP reported the day after the 1983 incident. The dancer was a new employee at San Francisco’s Condor Club (said to be one of the first, if not the first, topless bar). The man was her boyfriend, the club’s bouncer. And the trick piano was part of topless-dancing pioneer Carol Doda’s act—a white baby grand that lowered her from the second floor. During Ferrozzo’s assignation with the dancer, the piano’s switch was somehow activated, lifting him partway to heaven before deadly contact with the ceiling sent him the rest of the way.

4. Linos // Killed with a Lyre

One of the greatest music teachers of mythic Ancient Greece, Linos took on Herakles as a pupil. According to the historian Diodorus Siculus, the demi-god “was unable to appreciate what was taught him because of his sluggishness of soul,” and so after a harsh reprimand he flew into a rage and beat Linos to death with his lyre. Herakles dubiously used a sort of ancient stand-your-ground law as a defense during trial and was exonerated. Poor Linos: an honest man beaten by a lyre.

5. Sophia Rasch // Suffocated While a Piano Muffled her Screams

No one better proves George Bernard Shaw’s quip that “hell is full of musical amateurs” than Susannah Koczula. “I have seen Susannah trying to play the piano several times—she could not play,” 10-year-old Carl Rasch testified at Koczula’s 1894 trial. Susannah, the Rasch’s caregiver, distracted little Carl, sister Clara, and their neighborhood friend Woolf with an impromptu performance while a gruesome scene unfolded upstairs: Koczula’s husband tied and suffocated Carl and Clara’s mother, Sophia Rasch, before making off with her jewelry. “She banged the piano,” explained Woolf. “I heard no halloaing.”

6. Marianne Kirchgessner // A Nervous Disorder Acquired Playing the Glass Armonica

Benjamin Franklin invented the glass harmonica, or armonica, in 1761, unleashing a deadly scourge upon the musical world. “It was forbidden in several countries by the police,” wrote music historian Karl Pohl in 1862, while Karl Leopold Röllig warned in 1787 that “It’s not just the gentle waves of air that fill the ear, but the charming vibrations and constant strain of the bowls upon the already delicate nerves of the fingers that combine to produce diseases which are terrible, maybe even fatal.” In 1808, when Marianne Kirchgessner, Europe’s premiere glass armonica virtuoso, died at the age of 39, many suspected nervousness brought on by playing the instrument.

7. Charles Ratherbee // Lung Disease Possibly Caused by Playing the Trumpet

One summer day in 1845, Charles Ratherbee, a trumpeter, got into a fight with Joseph Harvey, who rented space in a garden from Ratherbee and was sowing seeds where the trumpeter had planned to plant potatoes. When confronted, Harvey became upset and knocked Ratherbee to the ground with his elbow. Two weeks and five days later, Ratherbee was dead.

Harvey was arrested for Ratherbee’s death, but a doctor pinpointed another killer: An undiagnosed lung disease made worse by his musical career. “The blowing of a trumpet would decidedly increase [the disease],” the surgeon testified at Harvey’s manslaughter trial. When asked if he was “in a fit state to blow a trumpet” the surgeon replied bluntly, “No.” Harvey was acquitted and given a suspended sentence for assault. The trumpet was never charged.
