 Gopalakrishana Theatre. Karanodai Bridge 
Built by the British Engineers this is one of the oldest bridge in the Chennai region which is on Chennai-Kolkata National Highway 5 connecting Chennai and Northern parts of India. Residents of Karanodai recalled the existing facility came up after the 125-year-old Karanodai bridge became dysfunctional fifteen years ago when its three spans were washed away by heavy flows in the river, caused due to the monsoon rains. A few two-wheelers continued to use it until the facility completely collapsed in December 2007.
