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

istock

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.

15 Educational Facts About Old School
DreamWorks
DreamWorks

Old School starred Luke Wilson as Mitch Martin, an attorney who—after catching his girlfriend cheating, and through some real estate and bitter dean-related circumstances—becomes the leader of a not-quite-official college fraternity. Along with his fellow thirtysomething friends Bernard (Vince Vaughn) and newlywed Frank (Will Ferrell), they end up having to fight for their right to maintain their status as a party-loving frat on campus.

The film, which was released 15 years ago today, marked Vaughn’s return to major comedies and Ferrell’s first major starring role after seven years on Saturday Night Live. Here are some facts about the movie for everyone, but particularly for my boy, Blue.

1. THE IDEA ORIGINATED WITH AN AD GUY.

Writer-director Todd Phillips was talking to a friend of his from the advertising industry named Court Crandall one day. Crandall had seen and enjoyed Phillips's movie Frat House (1998) and told his director buddy, “You know what would be funny is a movie about older guys who start a fraternity of their own.” After being told by Phillips to write it, he presented Phillips with a “loose version” of the finished product.

2. SOME OF THE FRAT SHENANIGANS WERE REAL.

While Crandall received the story credit for Old School, Phillips and Scot Armstrong received the credit for writing the script. Armstrong put his own college fraternity experiences into the script. “We were in Peoria, Illinois, so it was up to us to entertain ourselves," Armstrong shared in the movie's official production notes. "A lot of ideas for Old School came from things that really happened. When it was cold, everyone would go stir crazy and it inspired some moments of brilliance. Of course, my definition of ‘brilliance' might be different from other people's.”

3. IVAN REITMAN HELPED OUT.

Ivan Reitman, director of Stripes and Ghostbusters, was an executive producer on the film. Phillips and Armstrong wrote and rewrote every day for two months at Reitman’s house, an experience Phillips described as comedy writing “boot camp.”

4. THE STUDIO DIDN’T WANT VINCE VAUGHN.

It didn’t seem to make a difference to DreamWorks that Phillips and Armstrong had written the role of Bernard with Vince Vaughn in mind—the studio didn't want him. After his breakout success in Swingers, Vaughn had taken roles in dramas like the 1998 remake of Psycho. “So when Todd Phillips wanted me for Old School, the studio didn’t want me,” Vaughn told Variety in 2015. “They didn’t think I could do comedy! They said, ‘He’s a dramatic actor from smaller films.’ Todd really had to push for me.”

5. RECYCLED SHOTS OF HARVARD UNIVERSITY WERE USED.

The film was mainly shot on the Westwood campus of UCLA. The aerial shots of the fictitious Harrison University, however, were of Harvard; they had been shot for Road Trip (2000).

6. VINCE VAUGHN FANS MIGHT RECOGNIZE THE CHURCH.

In the film, Frank gets married at Westminster Presbyterian Church in Pasadena, California. Vaughn and Owen Wilson were in that same church two years later for Wedding Crashers (2005).

7. WILL FERRELL SCARED MEMBERS OF A 24-HOUR GYM.

Frank’s streaking scene was shot on a city street. As Ferrell remembered it, one of the storefronts was a 24-hour gym with Stairmasters and treadmills in the window. “I was rehearsing in a robe, and all these people are in the gym, watching me. I asked one of the production assistants, ‘Shouldn’t we tell them I’m going to be naked?’ Sure enough, I dropped my robe and there were shrieks of pure horror. After the first take, nobody was at the window anymore. I took that as a sign of approval.”

8. FERRELL REALLY WAS NAKED.

Ferrell justified it by saying it showed his character falling off the wagon. “The fact that it made sense was the reason I was really into doing it, and why I was able to commit on that level," Ferrell told the BBC. "If it was just for the sake of doing a crazy shot, then I don't think it makes sense.” Still, Ferrell needed some liquid courage, and was intimidated by the presence of Snoop Dogg.

9. ROB CORDDRY WAS NOT NAKED, BUT HE STILL HAD TO SIGN AWAY HIS NUDITY RIGHTS.

Old School marked the first major film role for Rob Corddry, who at the time was best known as a correspondent for The Daily Show. He had a jewel bag around his private parts for his nude scene, but his butt made it into the final cut. He had to sign a nudity clause, which gave the film the right to use his naked image “in any part of the universe, in any form, even that which is not devised.”

10. SNOOP DOGG AGREED TO CAMEO SO HE COULD PLAY HUGGY BEAR IN STARSKY & HUTCH.

Phillips admitted to essentially bribing the hip-hop artist/actor, using Snoop Dogg’s desire to play the street informant in the modern movie adaptation of the classic TV show (which Phillips was also directing) to his advantage. “So when I went to him I said, 'I want you to do Huggy Bear,' he was really excited. And I said, 'Oh yeah, also will you do this little thing for me in Old School a little cameo?' So he kind of had to do it I think."

11. SNOOP WANTED TO HANG OUT WITH VINCE VAUGHN ON SET, BUT NOT LUKE WILSON.

Vaughn and his friends accepted an invitation to hang out in Snoop Dogg’s trailer to play video games on the last day of shooting. Vaughn recalled seeing Luke Wilson later watching the news alone in his trailer; he had not been informed of the get-together.

12. WILSON WAS TEASED BY HIS CO-STARS.

Vaughn, Wilson, and Ferrell dubbed themselves “The Wolfpack”—years before Phillips directed The Hangover—because they would always make fun of each other. A particularly stinging exchange had Ferrell refer to Legally Blonde (which Wilson had starred in) as Legally Bland. Wilson said it didn’t make him feel great. Wilson retorted by telling Ferrell that "the transition from TV to the movies isn't a very easy one, so you might just want to keep one foot back in TV just in case this whole movie thing falls through!"

13. TERRY O’QUINN SCARED HIS SONS INTO THINKING THEY WERE TRIPPING.

Terry O’Quinn (who went on to play John Locke on Lost the following year) agreed to play Goldberg, uncredited, in what was a two-day job for him. He neglected to inform his sons he was in the movie, and when they saw it, one of them called their father. “I got a call from my sons one night, and they said, ‘What were you doing in Old School? We didn’t even know you were in it!’ They said, ‘We’re sitting there, and the first time we see you, it’s, like, in a reflection in a window. And when we saw it, and we both thought we were, like, tripping or something!’”

14. THE EARMUFFS WERE IMPROVISED.

Before filming, Vaughn worked with Ferrell to figure out their characters' backstories and how they knew each other; he credited that with helping him figure out who Bernard was, which led to several ad-libbed moments. “The earmuff scene where he swears in front of the kids, and then I tell the kid to earmuff, that all is off the cuff. But that stuff is a lot easier to do when you know who you are and your circumstances, and who your characters are,” Vaughn explained.

15. FERRELL AND VAUGHN DIDN’T LOVE A SCRIPT FOR A SEQUEL.

Armstrong had written Old School Dos in 2006, which saw the frat going to Spring Break. Ferrell said that he and Vaughn read the script but felt like they would just be “kind of doing the same thing again.” Wilson, on the other hand, was excited over the new script.
