Road plates are always a staple in any Lego city. Without them, your city would look cluttered and unorganized. I got these road plates over 10 years ago. The road itself is 18 studs wide, and on the outer edge of the quarter circle there is a huge grass area where you can build houses, skyscrapers, or any building you want. The road is divided into two lanes by a solid white line (in Canada and US, this means traffic is flowing in the same direction in both lanes and passing is not allowed).

There is a problem today regarding the size of road plates. Currently most Lego vehicles are at least 6 studs wide, if not more, which means that a modern vehicle will dwarf into the other lane if placed on an old road plate. These older road plates were designed for smaller 4 stud wide vehicles. Not only this, but newer road plates have a completely different design, and the road is two studs wider. This means that placing a new and old road plate adjacent to each other will look very awkward.

Overall, these road plates are great but they are now obsolete and won't fit nicely with modern City sets. If you prefer old road plates over the current ones I suggest going to Bricklink to purchase them.
