Countries around the world have pumped millions and even billions of dollars into huge construction projects that make our lives better.

But some mega projects should have been thrown into the garbage at the planning stage.

So grab a hard hat and a high-vis jacket because it's time to check out the most useless mega projects in the world.

You're listening. You're listening. You're listening. You're listening. I'd be amazed.

Hawaii is a beautiful place. It's got beaches, grass skirts, coconut bras, oh, and a super expensive blight on the landscape.

The H3 Interstate. Now I know what you're thinking. Interstate? Hawaii? That's one big highway.

Well here's the thing. It doesn't connect to any other state.

The name just means it's been funded by the federal government. So rather than spanning 2,500 miles to the nearest state, California, it spans just 15.

From northwest of downtown Honolulu to the Marine Corps Base Hawaii.

Oh, even so, it still cost a colossal $1.3 billion to build, or $80 million a mile.

Geez, back in 1960, when the road was first authorized, people weren't happy.

Not only was it set to level vast numbers of trees, but there were also sacred temples and funerary bounds in the area that were super significant to native Hawaiians.

Because of this, people protested hard.

But constructors eventually got legal authorization anyway, and in

1989 they started building. Seven contractors and eight years later it finally opened in 1997.

So despite H3 taking 37 years and blowing the budget by a shocking amount. Are Hawaiians happy? Not at all!

Construction destroyed many of the sacred sites throughout the valley.

Now lots of people won't drive anywhere near the road for fear of being cursed by the dead,

so it's hardly even used.

If you were thinking of taking a smooth cruise through the Hawaiian countryside then,

best be checking your backseat before you set off.

Ugh! That's the real highway to hell.
