The Lego straight and crossroad set is a great way for your little one to expand his/her Lego town. Use the crossroad to manage and organise the town's traffic. You can place the crossroad right in the centre of the Lego town and get a Lego policeman to control traffic moving around four directions. While the crossroad is perfect for the town's centre, you can use the straight road as a path to enter and exit the town. Encourage your little one to use their creativity and make complete use of these highly useful straight and crossroad toy plates.
