|Outer Ring Road, Chennai|
The Outer Ring Road, officially state highway 234 (SH 234), is a major transport corridor being operational along the periphery of Chennai Metropolitan Area (CMA) by the Chennai Metropolitan Development Authority (CMDA). It is 62 km long connecting GST Road at Perungalathur, GST Road at Vandalur, NH 48 (GWT Road) at Nazarethpettai, NH 716 (CTH Road) at Thiruninravur to NH 16 (GNT Road) at Vijayanaallur and to TPP road at Minjur. On 29 August 2010, the then Tamil Nadu Deputy Chief Minister M. K. Stalin laid the foundation for the first phase of the project from Vandalur to Nemilichery covering a distance of 30 kilometres (19 mi). The Road generally covers Developing areas like Avadi West such as Thiruninravur, Pattabiram, Nemilicheri, Muthapudupet, Mittanamallee, Morai, Veerapuram, and Thirumullaivoyal (Avadi SIDCO Industrial Estate). Chennai Outer ring road had a plan of Chennai metro rail CMRL which is going to build up at gap between two roads.
The Project was developed in 2 phases with 2 segments each.
The Phase 1 of the project covers a distance of 29.65 km. 10 Grade separators at major junctions have been planned along this route. It also includes 50 bus bays on both sides and also truck lay-byes for parking of around 100 trucks. Phase I of this project was implemented by GMR, and the project was originally expected to be completed by June 2012. Phase I was thrown open to the public on 29 August 2014 the then Chief Minister of Tamil Nadu J. Jayalalithaa through Video conferencing.
The Segment I extends from GST Road (Vandalur) to NH48 (Nazarethpettai) covering a distance of 19.7 km. The development covers an area of about 265.38 Hectares.
The Segment II extends from NH48 (Nazarethpettai) to CTH Road (Pattabiram) covering a distance of 9.5 km. The development covers an area of about 140.9 Hectares.
The Phase 2 covers a distance of 33.1 km.
The Segment III extends from CTH Road (Pattabiram) to GNT Road (Redhills) covering a distance of 18.8 km. The development covers an area of about 258.02 Hectares.
Price Waterhouse Coopers (PWC) has done a micro market study on the development of 50 m along the road. It has suggested that the components of the development could include a 5-star hotel, retail segments – including an "auto main street" where the ORR connects industrial suburbs that house automobile giants such as Hyundai, Ford and Renault Nissan – and facilities like multiplex, residential, hospital, commercial, warehouse and green spaces. Developers would be identified through open competitive bidding for these projects.
The region close to NH-45 is seen as a high-growth area covering the Chennai neighbourhoods places Vandalur, Mannivakkam, Mudichur, Thiruninravur, Pattabiram, Muthapudupet, Morai, Malayambakkam-Mangadu, Minjur and Ponneri (Smart City). This would be the location for a 5-star hotel.
Localities near Minjur and Ponneri, which are hubs of automobile and component industries, would be the ideal locale for the auto main street, which is a niche retail for the automobile industry for which about 50 acres (200,000 m2) have been earmarked.
Residential areas have been planned for more than 150 acres near Minjur, Ponneri while residential spaces have been planned at Malayambakkam, Nazarethpettai, Agaramel and Poonamallee.
A major warehouse has been planned in Minjur, Nemilichery (near Pattabiram).
Pattabiram would have a logistics facility.
