Want to know about designing of Flyovers...it will very helpfull for my final year project.

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. The presence of the Gemini Studios, which was demolished later, resulted in the flyover coming to be known as Gemini Flyover and the area being referred to as the Gemini Circle.

On two sides of the circle roundabout below the centre of the flyover are two identical statues of a man controlling a horse placed there to commemorate the banning of horse racing.

Anna Flyover has been beautified with other elements such as water fountains, landscaping of its 24,000 square feet (2,200 m2) traffic islands, cove lighting under the traffic movement area, restoration of the horse statue, a toilet for the police personnel, murals depicting social messages, and so forth.
