To help facilitate commerce between Delhi and Mumbai, India’s government began developing a 1,350-kilometer, eight-lane expressway between the two cities. The highway will cut travel time from 24 hours to 12 hours. Larsen & Toubro is responsible for designing and building a 23.7-kilometer section between Mumbai and Vadodara. Their initial plan rapidly became complex because they had to build around an unstable ravine and design interchange loops and ramps with toll plazas to connect the existing highways.  

Larsen & Toubro knew that OpenRoads Designer would help them create a 3D model of the project and determine how to overcome its challenges. The application allowed them to accurately model the undulating land in the ravine, which assisted with cross drainage structure placement. They also used OpenRoads Designer to simplify the interchange layout and resolve any clashes with existing roads and structures, reducing construction design by 1.5 months. The new expressway reduces vehicle operating costs and travel time by 50%.
