Anna Flyover, also known as Gemini Flyover, is a dual-armed flyover in the central business district of Chennai, India. Built in 1973 and dubbed one of the top-rated flyovers in the country, it is the first flyover in Chennai and the third in India, after the ones at Kemps Corner and Marine Drive in Mumbai. It was the longest flyover in the country when it was built. Its main purpose is to allow traffic movement on Mount Road—now renamed Anna Salai—near Nungambakkam High Road (Uthamar Gandhi Salai) to continue unhindered by the cross traffic.
