General Information:
A4 is in an interesting route as there is 2 parts to it, the longer section is named Esk Highway (formerly Esk Main Road) and runs from Cleveland to Falmouth, and the shorter section is named Elephant Pass Road, and is a spur from St Marys to Chain of Lagoons - both acting as connectors to the Tasman Highway (A3).
A4 is the principal link between the Midland Highway and Tasman Highway on the East Coast. It carries a significant number of heavy vehicles and is widely used by tourists.
