Mumbai, March 25 -- The long-pending revamp and concretisation of the Sant Namdev Maharaj Flyover, popularly known as the Parel TT Bridge, began on Tuesday evening marking the start of a major upgrade on one of central Mumbai's busiest connectors. While the project may lead to traffic snarls, it is expected to be over by the end of May. The flyover is a key connector in central Mumbai and plays a vital role in dispersing traffic between Parel, Dadar and nearby areas. As the concretisation work started, barricading began at 5 pm. Northbound vehicular movement was halted on Tuesday evening, while southbound traffic will be restricted between 10 pm and 4 pm everyday. When HT visited the site on the first day of the revamp work, traffic had slowed considerably. However, civic officials said that since only one side of the bridge had been shut off traffic could still be managed. Had the entire bridge been shut down, it may have led to worse traffic snarls. Built around 1980 the flyover has long been flagged for poor conditions. The revamp project focuses on strengthening the ageing flyover through structural repairs rather than demolishing and rebuilding it....
