The 50km stretch that extends from Madhya Kailash temple situated in Adyar right up to the south of Mamallapuram in Kanchipuram district is known as Old Mahabalipuram Road (OMR) or State Highway 49 A (SH-49A). The road strategically merges with East Coast Road (ECR) and yields the most convenient method of commuting between the southern peripheral localities in Chennai such as Thiruvanmiyur, Palavakkam, and Neelankarai.
The development of this road led to the emergence of IT/ITeS companies such as Satyam Computer Services, HCL Technologies, Accenture India, and Infosys in the area, giving OMR the IT Corridor title. The road harbours multiple micro markets such as Taramani, Perungudi, Thoraipakkam, Karapakkam, and Sholinganallur, generating a prominent real estate market with escalating demand for commercial and residential properties.
The locality consists of resourceful social infrastructure developments. Noteworthy educational institutions situated along this stretch include Sishya OMR School, American International School, Abacus Montessori School, MNM Jain Engineering College, Dhanraj Baid Jain College, and St Josephs College of Engineering.
