It also includes 50 bus bays on both sides and also truck lay-byes for parking of around 100 trucks. The Phase I project is being implemented by GMR, and the project is expected to be completed by June 2012. Phase I is thrown open to public on 29th August 2014, by the present Chief Minister of Tamil Nadu, through Video conferencing.

Planned Developments (PPP mode)

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.[1]
