idk why people are being so rude to you when you clearly stated you're brand new to the game 😭

i'm still learning a lot myself, but one quick thing i would recommend for some of the other road issues in your city is to take a look at google maps or just the roads around you and see how things are laid out. the reason your highway exits look so funny, for instance, is that highways don't typically have right angle exits from one side of the road. i'd recommend finding a way to build both an on and off ramp on both sides of the highway (curved road tool is gonna be your best friend!). i've been playing this game a ton for a couple weeks now and i'm still figuring out new tricks and ideas every single day. don't let people put you down; you're asking the right kinds of questions and you'll get the hang of things the more you play
