Abstract
Chennai is the fourth largest city in India with a population of about 8 million. Phase 1 of the Chennai Metro Rail project, currently in progress, comprises two corridors of about 47 km long and 32 stations. Chennai Central Metro station, located in the middle of the city, is an underground-interchange station between the two corridors and also a terminal station for one of the corridors. Due to its unique crossover arrangement, the platforms of the two corridors will be staggered, and the station is about 300 m long and constrained between a canal (c.1882) on one side and a busy road junction on the other side. Strategically located on one of the busy arterial roads – EVR Periyar Salai – and in front of the Chennai Central long-route railway station, the upcoming metro station will provide traffic integration with existing transport modes. Diversion of dense pedestrian and vehicular traffic continuously flowing through this location during construction plays a major role in the design and construction sequencing. The proposed metro station is also surrounded by at least four declared heritage buildings. The architectural and structural design of the above-ground metro structures will strike a commonality among the adjoining heritage buildings of different architectural styles, as well as exhibit a contemporary look.
