For comparison, Pete Kostelnick ran across America on foot with a world record time of 42 days, 6 hours, 30 minutes from San Francisco's City Hall to New York's City Hall in 2016.

My dad used to say, "The interstate is incredible. You can drive non-stop from the Atlantic to the Pacific and not see a damned thing."

I like how the highest ranking military officer in one of the greatest war mankind has fought and his conclusion was: "Man, infrastructure is really important"

@IBeforeAExceptAfterK

It's funny how back in 1919, trains were considered the dominant form of transport, with roads in desperate need of improved infrastructure. Now it's the opposite.

@jackbates7467

It's a shame we didn't take more from the Autobahn network, not going through city centers, allowing for no speed limits where practical, actually adhering to lane discipline, etc...

@grahamturner2640

Fun fact about the Interstates: On occasion, they were also used to experiment other things. The main one I know of the I-19, which was an experiment to see if America could convert to the Metric system. I was on it recently just to see it, and apparently, it's not too different from other Interstates, but most distance-related stuff is in meters/kilometers instead of miles. Exit numbers are based on the distance in kilometers (e.g. exit 101 is probably the last exit going north before you get to the I-10, even though the highway is only 62 miles long) and instead of mile markers, you get kilometer markers. The only thing that isn't in metric is speed limit signs, which are in miles per hour.

Eisenhower gets seldom recognition for what he did for science in america...he was a visionary....father of NASA...father of interstate

“A 7-hour trip from DC to Maryland”

Me, a Marylander: Did you just say SEVEN HOURS FROM DC TO MAR- you know what, that makes perfect sense and is still quite accurate

@noumanintown

That Eisenhower reveal was fantastic. What a legend.

Another cool thing: they have long sweeping turns so you need to pay more attention and it’s harder to doze off. Every 5-10 miles though, they have a long straight section which is there in case the military needs to set up an emergency air base. There’s thousands of potential spots to turn into a runway all around the country. Brilliant design. Also, the interstates in West Virginia have parts that don’t comply with the regulations because they were built before the regulations came out and it would take too much work and money to change it.

@jacob_tung

The construction of I-70 through Glenwood Canyon deserves a video of its own. The balancing of construction with environmental protection was truly amazing.

@dominicmariano9201

My father is a former military logistics specialist. He always told me that Ike's plan for the interstate system was to connect military bases, but also serve as emergency runways.  This is really obvious on Oahu, where the interstates all terminate at military bases, and the section of H-1 near the airport is clearly engineered to accommodate landing a C-130 or C-17 cargo plane.

@maxwellweiss9849

The man whose idea it was to not have any stoplights on these highways is probably basking in glory in the heights of Heaven.

@randomguy3814

Fun fact: Interstate 95 is the most recently completed interstate, having been completed in 2018 with the completion of the I-95/Penn Turnpike Interchange Project in Bristol, PA.

@charlespletzke8311

Fun fact: the interstates are numbered so that even numbers are west-east running and odd run north-south. Three digit interstates are loops for a given interstate. The lower number interstates are further south and/or west (i5 runs in the west coast states whereas i95 runs east coast states).

@Xaqaria

I REALLY appreciate that you have moved to a model of sharing a companion video on Nebula vs. an extended version.

With the extended versions I would debate if the frustration of scanning through the video to find the extra content was worth it.  I usually wouldn't even try.

With the companion video, it is clear cut and easy.  I believe I have watched every one you've released.  Please tell your peers they should try this as well.  It's increasing the value of Nebula and my engagement with the app.

@Crazcosmopwnu

If only Cities Skylines was around back then so that they could've built the interstates with proper lane mathematics

@Thrifty032781

I-95 had this strange discontinuity near Philadelphia.  You would drive up I-95, then turn south in this sort of upside down U.  You are shunted over to I-295, then cross into New Jersey on I-195 and rejoin 95 on the New Jersey turnpike.

They fixed this pretty recently --- fall 2018.  I don't remember exactly how, but now I-95 connects to the Pennsylvania turnpike.
