From May Day Park Shaft both TBM will proceed to Gemini Station, passing the stations of Govt. Estate, LIC Building and Thousand Lights. The fabric of lining elements and the evacuation of the excavated ground are done in May Day Park Shaft. Another 2 will be assembled at the Cut & Cover Box Ramp near Saidapet Station. From the starting shaft both TBM will proceed to Gemini Station, passing through Saidapet, Chamiers Road and Teynampet. The cross-passages for both tunnels will be constructed every 250 meters. GEMINI SAIDAPET = TBM Exit Point = TBM Starting Point
