What is the longest line road?

Okay, so you want me to make this text sound more like a real person talking, right? I can definitely do that! Let's give it a shot:

"So, you wanna know about the longest straight road? Okay, get this – there's a road in Saudi Arabia, Highway 10, that's like, completely straight for 240 kilometers! That's... insane! I mean, seriously, can you even imagine? I get restless driving on the highway for just an hour, you know? I start fiddling with the radio, snacking... anything to break the monotony.

And this road? It's smack-dab in the middle of the desert, apparently. I picture endless sand. That sounds... well, uniquely mind-numbing, doesn't it? Like, I bet you could start seeing mirages or something after a while.

The craziest thing is, I read somewhere that it was built specifically for King Fahd. Just for him! To connect his farm in Haradh to somewhere else. That's dedication... or maybe just royal privilege, haha. I wonder if they had to, like, adjust the route to keep it perfectly straight? I mean, the earth isn't perfectly flat, is it? Seems like a logistical nightmare! Anyway, yeah, 240 kilometers of pure, uninterrupted straightness. My brain hurts just thinking about it!"
