The Brihanmumbai Municipal Corporation on Tuesday floated a fresh tender for its ambitious project of building an elevated road connecting P D Mello Road (Orange Gate) with Grant Road in south Mumbai.
The bridge will pass through some of the heavily congested localities of Mumbai and this new tender was floated by scrapping the previous tender, which was floated in February last year.
The cost of the project has also doubled since the overall cost for this project in the previous tender was pegged at Rs 638 crore, while the cost of the project in new tender stands at Rs 1,170 crore.
P Velrasu, additional municipal commissioner (projects), said the new project will consist of a cable-stayed bridge, owing to which there has been a cost escalation.
“Earlier, we were only considering construction of a normal flyover that would pass above the existing Hancock bridge. Later, we found out that a cable-stayed bridge would be more feasible for this project. Therefore, a new tender was finalised after considering and incorporating all the design changes in the project,” Velrasu told Express on Tuesday.
In a cable-stayed bridge, the weight of the deck is supported by straight high-tension diagonal cables that remain attached with a vertical tower. In Mumbai, the Bandra Worli Sea Link (BWSL) is a cable-stayed bridge.
Velrasu also said that in the previous project, the provision of removing the utilities was not considered. However, a fresh study has been considered before floating the new tender and all the utility channels will be removed.
The said project will also be built on mono piles so that it consumes less space on the surface. The proposed arterial road will be like a dispersal arm that will originate from Orange Gate, which is approximately 1-kilometre away from the P D Mello’s drop of the Freeway.
The proposed flyover will be 5.6-kilometre-long and it will connect the southern end of the Eastern Freeway with Grant Road. This stretch is severely congested since it originates from the southern drop of freeway which becomes a bottleneck due to the heavy influx of vehicles during peak hours.
The Eastern Freeway is a 17-kilometre-long high-speed corridor that connects the Eastern Express Highway (EEH) in Chembur at Eastern suburbs with P D Mello Road in south Mumbai, just near the Chhatrapati Shivaji Maharaj Terminus. This Freeway became operational in 2014 and since then has played a key role in connecting the southern end of the city with eastern suburbs.
