Abstract : Viaducts and Bridges play a pivotal role in transportation infrastructure, serving as critical links between regions and accommodating various modes of transportation, including High-Speed rail (HSR), Railways, Metros, and Highways. The design and construction of bridges for HSR projects differ significantly from other modes of transport. Mumbai Ahmedabad High Speed Rail (MAHSR) is a transformative infrastructure initiative in India that aims to revolutionize the country’s transportation landscape. MAHSR covers a distance of approximately 508 kilometers and will traverse through the states of Maharashtra and Gujarat with a design speed of 350 kmph. Design concepts for structures in MAHSR project are mostly based on Japanese Railway Standards and Guidelines which is a proven technology for Shinkansen High Speed Railway network in Japan. In this paper, one of the unique requirements of MAHSR project i.e., ‘Articulation of Prestressed Concrete (PSC) Box Girder Bridges’ is covered. This paper aims to provide information on bearings and stoppers for MAHSR viaducts and bridges and comparison with conventional system. The paper also touches upon the seismic force assessment for the project.
