In Phase-I, the 20.1 km stretch between Madhya Kailash Temple Junction to Siruseri is widened to dual three lane carriageway with median, service road, pedestrian footpath and planter strip. The ECR Link Road has also been improved to dual two lane carriageway.

Another significant feature of the Project is the construction of service trenches/ducts for conveying utility lines including electrical, telephony and optic fibre cables/wires so as to avoid digging in future. The water and sewer lines are also being conveyed under the footpath.

Landscaping and arboriculture, road side arts and sculpture works and value added services have also been undertaken. A twelve lane state-of-the-art toll plaza has been located at Perungudi with a modern Toll Administration-cum-Office along with four satellite plazas at Pallavaram road, ECR Link road, Medavakkam road and Exit plaza at Navalur.

The six lane main carriageway of Rajiv Gandhi Salai had been inaugurated and opened to public on29th Oct 2008. Toll Operation commenced on 15th December 2008. Four lane ECR Link road connecting Rajiv Gandhi Salai to ECR at Sholinganallur had also been completed along with rehabilitation of the old bridge.

Bus Shelters and Foot over bridges have been erected at appropriate locations along the road. Service Road and Foot Path have been fully completed for a length of 20.1 kms on both sides of the road.
