The Sardar Patel Ring Road in Ahmedabad demonstrates how public-private partnership (PPP) models can be used effectively for city infrastructure development. Ahmedabad Urban Development Authority (AUDA) has been working with the private sector to realize this prestigious project.

Ahmedabad has become a mega city and development in outer areas is expected to accelerate further. The Revised Development Plan (2011) proposes an additional 64 sq. km of urbanizable land over the next ten years. As per the plan, the population is expected to reach 46 lakhs and 60 lakhs in the former Ahmedabad Municipal Corporation (AMC) and AUDA areas respectively within a period of 10 years. It was therefore important to ensure planned growth with good road network and infrastructure in the developing areas of the city.

Further, there is the worsening problem of traffic congestion within the city due to mixing of the regional and city traffic. This is most prominent on the eastern
(Naroda- Narol Highway) and the western (Gandhinagar Sarkhej Highway) bypasses, which have become part of the city as it has grown rapidly in the past few years. To ease the traffic congestion on the inner radial roads, the '132 feet ring road' was constructed but over time, traffic volume on the same has increased beyond predictions. In this situation, it was important to divert the regional traffic out of the city.

The 60mt wide ring road was conceptualized to:

  • reduce traffic congestion on peripheral roads,
  • segregate regional and urban traffic,
  • increase connectivity,
  • guide the development and expansion of Ahmedabad in a larger region

Conceived as the outer most 'ring' encircling Ahmedabad urban agglomeration, the ring road encompasses an area of about 400 sq km which includes most of the developed and developing areas and covers a population of 40 lakhs. The entire length of this road is 76.313 km. Radiating from the city, there are 19 major roads of
various categories either connecting or crossing this road. The entire road is divided into four links to facilitate investigation and preliminary design.

The SP ring road has been planned as a four lane divided road with envisaged facilities like exclusive bus lane for Bus Rapid Transit System (BRTS), service road, footpath, utilities and plantations on either sides. With continuous plantation along the road, it is visualized to develop a “green fort” around Ahmedabad.

The overall project has been systematically divided into three phases.

The key features of the three phases are as described below:

  • Phase 1 : It includes two laning of the entire stretch and four-laning of major stretches. It also included earthwork for four lane configuration. The total cost for this phase was Rs. 230 crores, which was met from AUDA's internal funds and through loans from financial institutions. The two-lane ring road started in 2001. Many portions of the road have been operational since 2003 and the entire ring road was completed in 2006.
  • In Phase 2, the existing two lanes are being extended to four lanes. This is being done on Build, Operate and Transfer (BOT) basis. The total cost of  construction of four-lane road is estimated at Rs.378 crores. The BOT document was floated in February, 2006. The work of four-laning on BOT basis has been awarded to a joint venture.
  • In Phase 3, will include extension of the ring road with facilities like control access, flyover and underpasses at major junctions crossing national highway, state highway, major district roads and important roads. It is proposed that 17 flyovers, 5 underpasses and 2 railway over-bridges will be built. There will be service roads, bicycle tracks, and exclusive bus lanes for Bus based Rapid Transit System (BRTS) and walkways on both sides. It has been proposed to develop 60 mt right of way (ROW) on western side and 78 mt ROW on the eastern side. The total cost is estimated at Rs. 460 crores.
