The Cahill Expressway is an urban freeway in Sydney and was the first freeway constructed in Australia, opening to traffic in 1958. It starts from the Eastern Distributor and Cross City Tunnel in Woolloomooloo, and runs through a series of sunken cuttings and tunnels between the Royal Botanic Garden and The Domain. It then runs on an elevated section across the northern edge of the Sydney CBD at Circular Quay, and then across the Sydney Harbour Bridge to North Sydney. It connects there to the Warringah Freeway.
It is named after the then New South Wales Premier John Joseph Cahill, who also approved construction of the Sydney Opera House. It is generally not well loved by Sydneysiders, who dislike its ugly appearance and its division of the city from its waterfront.
