We aren't permitted to ride on the sidewalks here in MN, but we do have a lot of bike paths that run next to the road, and often cyclists will turn off the bike path into the road at an intersection to go a direction the path does not go and vice versa. Generally when they do this they behave like really careful cars, only turning on the appropriate light, and waiting until the road is completely clear before turning. They generally don't walk across at the lights, but we have a huge bike culture here so drivers are used to seeing bikes. I'd recommend being extra careful until you've felt out the situation there.
