The project was conceived in 1992. The six-lane road (177 kilometres) was estimated to cost Rs 117 billion. The eventual ring road, with six lanes stretching out to 443 km, comes at the cost of Rs 185 billion while the same road with 177 km will cost approximately Rs 1150 billion. Changes in government caused delays and changes in the project and the total cost estimates shot up due to increased land acquisition, improvement of existing roads used in the project, shifting of utility installations, protecting commercial and residential areas and improvements to junctions.
