Tapleys Hill Road is a north–south arterial road which runs parallel to the coast through western Adelaide, Australia. This name covers many consecutive streets and is not widely known to most drivers except for the northernmost section, as the entire allocation is still best known as by the names of its constituent parts: Tapleys Hill Road proper, Brighton Road, Ocean Boulevard, Lonsdale Road, Dyson Road, Murray Road, and Gawler Street. This article will deal with the entire length of the corridor for sake of completion, as well to avoid confusion between declarations.
