Mumbai, Jan. 29 -- After facing sustained criticism over the design of a double-decker flyover in Mira-Bhayandar, the Mumbai Metropolitan Region Development Authority (MMRDA) has decided to carry out modifications ahead of the structure's scheduled opening next month. The flyover at Golden Nest Junction, part of the 13.58-km Mumbai Metro 9 (Dahisar East to Mira-Bhayandar) project, has been under fire on social media over the past three days, with commuters and activists flagging safety concerns over a stretch where four traffic lanes narrow abruptly into two. MMRDA is constructing four double-decker flyovers along the corridor, with the metro line on the upper deck and vehicular traffic below. Two of these flyovers are already operational. Of the remaining two, the Kashimira flyover is still far from completion, while the Golden Nest Junction structure is slated to open in February. It is the Golden Nest Junction flyover, built at an estimated cost of Rs.100 crore, that has become the focus of the controversy. Bhayandar-based activist Krishna Gupta has lodged a formal complaint with chief minister Devendra Fadnavis, deputy chief minister Eknath Shinde, who also chairs the MMRDA, and senior officials of the authority, questioning both the design and safety aspects of the flyover. Responding to the criticism, MMRDA officials told Hindustan Times on Wednesday that while several safety features are already in place to guide motorists to the downward ramp, more modifications will be made at the point where the ramp meets the flyover. "Already, a metal crash barrier, safety walls and signage are put in place. But as people are of the view that the spot is a potential accident-prone spot, we have started working on solutions," said an MMRDA official. According to officials, the proposed solution involves demolishing about 10-20 metres of the wall along the median and replacing it with kerb stones fitted with reflective delineators to improve visibility and lane guidance. "The work is unlikely to be completed within a fortnight, when it was scheduled to be inaugurated. There is a gaping hole about one metre wide at the median as both carriageways of the flyover are separate structures. This gap will have to be filled prior to laying kerb stones," said the MMRDA official. Apart from the flyover, MMRDA is also looking at partially opening the Metro 9 line in the first week of February, officials said....
