While a feasibility study was submitted for extending the Metro to Kelambakkam via Siruseri, it has been dropped due to low projected ridership. The proposal faced disapproval because the route lacks a significant concentration of educational institutions and offices. The study found that the line wouldn't meet the required 14,000 passengers per hour during peak hours, compared to the projected 20,000 for the Koyambedu-Avadi and Poonamallee-Paranthur extensions. The decision has caused disappointment among residents, particularly IT employees working in Siruseri who would have benefitted from the connectivity. However, the Metro Rail Corporation is considering an alternative route from Kelambakkam to Thiruporur, potentially even extending it to Mahabalipuram.
