The SEZ Corridor is an emerging corridor implementing a number of Special Economic Zones (SEZs) along the Grand Southern Trunk Road (NH 45) in Chennai.
The GST Road is widely made use of for SEZ projects due to its connectivity with various means of transport by road, rail and air.
This is evident by the presence of the Chennai International Airport, various railway stations parallel to the road, and also its connectivity to the complex road network of the National Highways Authority of India.
It is also emerging as a major IT SEZ region with a number of huge investments by Infosys.
Infosys has set up its largest development center in Mahindra SEZ while India Land Tech Park is developing a massive 500-acre (2.0 km2) SEZ which is estimated to have 20,900,000 sq ft (1,940,000 m2) office space for both IT and Electronics use.
