In a recent cost-benefit analysis of investments made by the Delhi government, the PWD studied the construction of 18 major flyovers/elevated roads during the period 2007-10. It found that the grade separator at Mukarba Chowk and corridor improvement of Road no. 56 in Anand Vihar were the most cost effective projects undertaken during the period under study.
According to the PWD, the parameters involved in the study include cost of the project, savings in terms of monetised value of man hours saved, savings in terms of monetised value of fuel saved due to reduction in travel time and gains in terms of carbon credits earned
“Grade separators at Mangolpuri, Mukarba Chowk, ITO Chungi, Shyamlal College and Anand Vihar recovered the cost of construction within the first year of their commissioning. This was not the case wit the RTR and IIT flyovers, which took almost four years to recover their cost,’’ an official said.
The RTR flyover cost Rs 50 crore and was completed in October 2010. Taking into account the saving on man-hours, saving on fuel and carbon credit, the study found that the RTR flyover project saved Rs Rs 5.94 crore in 2010. On the other hand, the project on the grade separator at Mukarba Chowk, which cost Rs 195 crore, saved Rs 334.42 crore in 2009 after it was completed in the same year.
The RTR, which serves as a key link to Delhi’s airport and NH-8, has been the subject of considerable debate — and the reason for a traffic nightmare — ever since a handful of Palam Marg residents, whose bungalows face the road, opposed the takeover of a service lane outside their houses for the project. The flyover was reduced to a single carriageway, resulting in a traffic bottleneck and daily chaos.
The final deck for going ahead with construction of a parallel flyover to the existing one-way RTR Flyover was cleared by Delhi Urban Art Commission (DUAC) only recently. The parallel flyover is expected to ensure smooth movement of traffic between IIT and the airport. “While the preliminary estimates have been sent to the government, we are still awaiting clearances before we can proceed to prepare for tenders,’’ an official said.
