The town's road system utilize a hierarchy of road sizes by design: the major roads are referred to as "Avenues", and the local-access roads referred to as "Streets". Ang Mo Kio Avenue 12 is an exception as it is a small road in an industrial estate in Ang Mo Kio. The town's avenues are arranged in a grid-like pattern, with the streets filtering traffic from the avenues to the individual blocks. The town itself is served by the Central Expressway, providing a rapid link from the town to the rest of the island via the expressway network.
