The roads are really easy once you get the hang of it! It's best to place your intersections first then your road. Make sure you have the grid lines on and choose the snap option. It's not called snap, something else. Then you select the road (it will then have blue lines) and drag it to the intersection, it should just snap into place. You'll know it did because you will get a cross walk.
Now that you read my incredibly fabulous (LMBO!) instructions, I'm going to go find you the tutorial.
