St. Thomas Mount-Poonamallee Road, popularly known as the Mount-Poonamallee Road (SH-55), is an arterial road in the city of Chennai, India. It runs for 11 kilometres from Kathipara Junction to the NH 4 highway connecting St. Thomas Mount with the suburb of Poonamallee. A 5-kilometre stretch of the Mount-Poonamallee Road is located in the Alandur taluk of Chennai district, part of Maduravoyal Taluk in Chennai district and the remainder in the Poonamallee taluk of Thiruvallur district.^[1]

Features

The road is divided into two sections. The first section from St. Thomas Mount to Nandambakkam, covering a distance of one kilometre, is narrower than the rest of the stretch and is known as Butt Road.

Real Estate development and IT parks

Mount-Poonamallee road has been identified as emerging commercial corridor, with increasing interest from real-estate developers for establishing IT parks and office spaces along the stretch. Several planned residential projects along the corridor have been converted into commercial developments to accommodate IT and IT-enabled services (IT/ITES) companies, particularly in areas such as Porur and Poonamallee, with the presence of DLF IT Park and Fintech City at Nandambakkam.^[2]^[3]

The stretch has been described as potential 'second IT corridor' for Chennai after Old Mahabalipuram Road (OMR), attracting mid-level multinational companies and Business Process Outsourcing firms. Large-scale IT park developments, including special economic zones (SEZs), have been proposed or are under-construction along the road, contributing to its transformation into a major employment hub.^[2]

Connectivity

The arterial road stretch is expected to benefit from improved connectivity with the under-construction Chennai Metro's corridors Red line and Yellow line passing through the road, which has been the key factor driving commercial development along the road.^[2]
