How are roads built? (Are We There Yet: Guide to Roads)?

Roads are like long paths that help cars, bikes, and people move from one place to another, just like how you walk from your house to school.

Building a road is like building a really big sidewalk, but for cars instead of shoes. First, workers dig up the ground to make space, it's like clearing out leaves in your backyard so you can lay down new grass. Then they put down layers underneath: one layer might be like a soft blanket to help with bumps, and another is like a strong base made of rocks or gravel.

Next, they add asphalt, which is like black chocolate that gets hard when it cools down. They use big machines called rollers, think of them as giant, heavy toys, to press the asphalt flat so cars can roll smoothly over it.

Sometimes there are lanes, like different colored paths for cars going in one direction or another. And if it's a bigger road, they might add sidewalks on the side, just like you have space to walk when you’re playing outside.

That’s how roads get built, one step at a time, just like your favorite game!
