This paper describes the key challenges faced in three recent long-span bridge projects in India and explains how they were overcome through the application of novel construction methods. They include constructability changes in the precast works for the Barapullah elevated corridor phase 3 in New Delhi, a temporary bamboo pile jetty system for Bihar’s New Ganga Bridge project near Patna and a combined precast yard with a load-out facility for the Durgam Cheruvu Bridge in Hyderabad. The new approaches adopted in these case studies resulted in considerable cost and time savings compared with the original plans.
