Nagpur Metro has successfully created a Guinness World Record by constructing the longest double-decker viaduct (metro) is 3,140 meters and was achieved by the Wardha Road in Nagpur. The double-decker viaduct of 3.14 km on Wardha Road has three metro stations – Chhatrapati Nagar, Jai Prakash Nagar and Ujjwal Nagar. These stations require special planning which are station specific to meet the functional requirements of themetro duly incorporating site specific constraints and double-decker viaduct requirements. The engineering thought process, concept, design and execution of these stations are no less than a challenge.
About the project:
- The project has already bagged records from Asia Book and India Book. Initially, the alignment of the highway flyover and metro rail were on same existing highway on Wardha Road, with independent piers at alternating locations proposed on the median.This was later reviewed and decided to integrate Highway Flyover and Metro Rail to form a double-decker viaduct.
- Double decker viaduct carries highway flyover at the first level and Metro Rail at second level making it a three-tier transportation system with the existing highway at ground level. This helped in avoiding additional land acquisition thus saving land cost and reducing construction time and project cost.
