Build an epic construction using the basic pieces included in the Hot Wheels City Track Expansion set. Expand the sets you already own or start from scratch with this complete track set. The set includes 10 track pieces, straight and curved, a square and a bridge, as well as 1 Hot Wheels® car. Each piece is compatible with other Hot Wheels City sets, allowing children to create their own Hot Wheels track as they imagine it. Additional sets are sold separately. Hot Wheels® help children improve their problem-solving skills while also encouraging a tendency towards exploration.
