Why go over mountains and rivers when you can just go under them? These are the works of infrastructure Jalopnik readers identified as the most stunning and stubborn works of roadway engineering the world over.
Welcome back to Answers of the Day — our daily Jalopnik feature where we take the best ten responses from the previous day's Question of the Day and shine it up to show off. It's by you and for you, the Jalopnik readers. Enjoy!
There's something intrinsically awesome about tunnels in their stubborn approach to engineering. If there's a mountain in the way, just blow your way straight through it! Or maybe they just acknowledge our inner Lord of the Rings-style dwarves.
The best tunnels, though, have an elegance to them that should be recognized.
Of course, the one thing we aren't showing you is exactly what it feels like to drive through these tunnels. Post your favorite videos of taking these underground passages in Kinja below.

10.) Tokyo Bay Aqua Line
Tokyo's super long descent-under-the water tunnel was previously a toll road. That meant that street racers used to take their cars up to top speed runs in the 10km-long stretch. Now that there's a toll, traffic has picked up and you get less hooliganism, but the engineering remains impressive.
9.) Big Dig, Boston
They took the city's biggest exposed roads and sunk them underground. Sure it was a massively over budget managerial nightmare, but the finished product is pretty impressive.
8.) Eisenhower Tunnel, Colorado
The Eisenhower Tunnel is impressive in its length and in its elevation, but there's one feature we love more than any other. Since it splits the Continental Divide, there can be completely different weather on the opposite side of the tunnel. You can drive in on a nice day and drive out into a blizzard.
7.) SMART Tunnel, Kuala Lumpur
That's ‘Stormwater Management And Road Tunnel.' Kuala Lumpur's massive tunnel doubles as a gigantic storm drain during monsoon season.
6.) Spiralen Tunnel, Drammen Norway
In this tunnel up the inside of a mountain in Norway, you actually drive upwards in from 50 feet to 2600 feet above sea-level in six loops.
5.) 1911 Elbe Tunnel, Hamburg
This is an elevator tunnel, and the original elevators (pictured above) are still in use over 100 years later. It's a time travel device back to some kind of paleofuturistic past.
4.) Chip Ganassi's Secret Wind Tunnel, Pennsylvania
In 2003 and 2004, hikers in Pennsylvania began to find discarded racing fuel drums near an abandoned PA Turnpike tunnel, and they'd hear the sound of loud V8 engines. Turns out Chip Ganassi Racing had turned it into a giant, full-size wind tunnel. This is about the coolest secret racecar engineering feat we can imagine.
3.) Guoliang Tunnel, China
You've seen it in those new Cadiallac ATS ads. This thing was carved out by hand. Unbelievable.
2.) Zhongnanshan Tunnel, China
This list wouldn't be complete without some Chinese mega-engineering, now would it? At 11.21 miles, this is the second-longest road tunnel in the world and the longest two-tube tunnel in the world.
1.) Lærdal Tunnel, Norway
And here's the longest road tunnel in the world. That's 15.23 miles underground. What's with the crazy colors? In the regular sections, the tunnel has plain white lights, but in the caves there are blue and yellow lights to keep people from falling asleep and crashing into the walls and dying.
Humans are not designed for this kind of travel, so we have to be tricked. Good thing we can always trust engineers.
