Mumbai's western coastline is transforming thanks to the ambitious Mumbai Coastal Road Project. Currently under construction, the 29.2-kilometer-long expressway will reduce travel time between South Mumbai and the Western Suburbs from 2 hours to 40 minutes. Mumbai is one of the most populous cities in the world. The rise in road traffic put pressure on the city’s infrastructure and led to poor air quality levels that were concerning. The highway is expected to serve 130,000 vehicles daily once it is finished. L&T Construction is developing the first 9.98-kilometer section that includes a curved superstructure. The sharp curvature of the interchanges and the different bridge span lengths, along with the marine conditions and the limited steel quantities requirements, posed geometry and structural challenges. This required detailed and precise structural modeling and analysis. Before construction started, the adaptation of monopile led to minimal environmental pollution by producing less construction waste which could deal with the sensitive environmental conditions of the Mumbai coast. Using Bentley software, L&T modeled and analyzed 150 spans in 30 days, cutting design calculation time by 50% and saving 200 days in design time. The accurate designs and visualization helped them to use materials efficiently which allowed them to reuse 12,500 megatons of structural steel and shorten the construction period by six months. In March 2024, a section of the road, officially named the Dharmveer Swarajya Rakshak Chhatrapati Sambhaji Maharaj Coastal Road, partially opened connecting Marine Drive and the Bandra-Worli Sea Link. #engineering #roads #bridges #transportation #digitaltwins #3Dmodeling Larsen & Toubro
