To ease traffic congestion at Signature Tower crossing, the National Highway Authority of India (NHAI) is considering construction of two underpasses or tunnels at the intersection, which connects the city to the Delhi-Gurgaon Expressway.
A joint team of Indian and Italian engineers and architects on Friday did a reality check of traffic snarls at the under-the-flyover crossing near Signature Tower during peak hours. The team also surveyed Iffco Chowk and Rajiv Chowk crossings.
An Italian engineer, who was part of the survey team, said, "Two separate tunnels can be constructed near Signature Tower. One to give a freeway movement to traffic coming from Huda City Centre and heading towards Iffco Chowk and the other tunnel will provide signal-free movement to vehicles from Maruti plant side towards Manesar."
The construction of two tunnels will solve the traffic problem to a large extent. The tunnels will not cross each other but they will boost traffic movement without any pause, the engineer said.
The surveying team members said they are also looking at the possibility of cloverleaf interchanges but the cost of two tunnels would be much cheaper.
The NHAI's apprehension is that the tunnel construction may damage the pillars of the existing flyover.
"That is why we are first working on the underpass possibility. It will take 10 to 15 days to prepare the design and we would submit it to NHAI, Haryana Urban Development Authority and the Municipal Corporation of Gurgaon," said Tarun Mathur, a bridge designer.
However, he said that the construction of cloverleaves would be difficult because of space crunch. Land paucity is a big hindrance at all under-the-flyover crossing points on the expressway.
A senior NHAI official said the underpass or cloverleaf would not damage the expressway. "We would give permission only after we see the design," the official said.
