Gurugram, Oct. 31 -- Illegal parking and poorly maintained roads and infrastructure combined with the dropping visibility has turned Gurugram's underground corridor, which helps ease traffic flow, into a safety hazard, motorists and experts say. At several key underpasses - near Hero Honda Chowk, Ambience Mall, Sohna-Badshahpur road, Rajiv Chowk and Subhash Chowk - commuters report illegal parking, poorly kept roads, missing signage, broken roofs, and flickering lights. The situation is further worsened by the low visibility in NCR - reported at 800 metres around on Thursday morning- as smog enveloped the region and the sky remained generally cloudy. An HT spot check at multiple underpasses in Gurugram raised concerns over commuters safety, with vehicular undercrossings failing on the illumination and safety standards prescribed by the Indian Road Congress, a national body for laying down designing standards for roads and highway construction. At approximately 1pm, taxis and auto-rickshaws were camped on the Ambience mall underpass towards Delhi-Gurugram-Jaipur (NH48) expressway, blocking one lane on each side at entry and exit points. "We know it's illegal to park here. But there isn't any waiting area for us," said Sajid (single name), a pick-and-drop autorickshaw driver. Mobile cart-owners near the underpass entry added that the traffic police inspect only one side at a time, allowing taxi and auto drivers to escape during checks. There were few working lights and the signs on its exit appeared to have faded. "This is the busiest route, yet we see no signage guiding us to the right speed limit or to not jump lanes," said Gurpal Singh, a daily commuter. According to a senior DLF official, maintenance of the underpasses, including their lighting and roads, is a year-long process, with dedicated inspection teams monitoring the situation dynamically. Other underpasses at Hero Honda Chowk, Tau Devi Lal Stadium-Medicity, Sohna-Badhshahpur road, Subhash Chowk and SPR, too, had long stretches with poor lighting illumination. Officials at NHAI acknowledged that concerns raised by the commuters. "We will direct contractors to fix lights and place signages at underpasses," the senior official added. A senior official at the Gurugram Metropolitan Development Authority (GMDA) said that concerns raised by commuters about its only maintained underpass at Huda City Centre are addressed swiftly without any delays. "Our teams on the ground rectify any visibility or monitoring issues whenever they persist," the official said....
