1km Nanganallur flyover to be first over city subway
The state highways department plans to build a six-lane, 1km flyover above the Thillai Ganga Nagar subway in seven years.This is to ensure movememt of traffic even during rain that usually submerges subways. The project, estimated to cost `85 crore, will take a year for tenders to be floated and another six years to be completed.
The metro wing of the state highways department is working on a detailed project report, minister for highways and minor ports Edappadi K Palaniswami announced in the assembly on Thursday , replying during a debate on the demand for grants.
The proposed flyover, highways department officials told TOI, will soar six metres above the road, while the subway is 5.5m below the road level. “The columns of the flyover will be at least 11.5 metres tall and will run along the subway ,“ said an official. We schedule construction for three years, but going by our experience in building rail over-bridges, this will take double that, over-bridges, this will take double that, primarily because the railways is slow in constructing its portion,“ he added.
All subways cutting across the rail way line in the area, at Thillai Ganga Nagar, St Thomas Mount and, Meenambakkam, are entirely flooded when it rains and access to areas like Velachery and beyond is cut off.
Welcoming the flyover plan, many residents said even a moderate spell of rain was enough to block the subway . “The road is wide and there is no traffic, even during peak hours. It is the rain that makes the subway a nightmare,“ said S Kannan of Adambakkam.
However, senior officials in the metro wing of the highways department seemed completely unaware of the proposal announced in the assembly . They insisted that the projects department was responsible for the project.
A source close to the minister clarified that the metro wing would execute the project and would have to start preparing the DPR, listing the number of vehicles crossing the particular junction, the quantity of land to be acquired and underground utilities to be shifted.
