A freeway, like the name suggest is a much larger highway that does not collect toll. In the East coast, you will be nickeled and dimed to death. In the Western States, such as Califonia, the freeway can have 5 to 6 lanes of traffic going one way with an equal number going in the other direction. You find this more in larger cities like Los Angeles. When these freeways go into the rural areas, the lanes can be reduced to only two like the ones in the East Coast. However, they are still free from all tolls.
