The proposed double-decker component of the Visakhapatnam Metro project has been revised to around 21 km. The change reduces the length of the double-decker section compared with the earlier proposal. The project is being planned to improve public transport connectivity across the rapidly developing city. The double-decker design combines a metro viaduct with an elevated road facility, helping optimise the use of available road space. The revised stretch is expected to cover important traffic corridors where congestion and future transport demand are major concerns. The metro project itself is planned as a wider network connecting several parts of Visakhapatnam. The double-decker section is among the key features proposed for the city's first metro system. The reduction in length is part of the latest planning changes being considered for the project. The revised design is expected to take into account engineering feasibility, traffic movement and overall project requirements. The metro is intended to provide faster and more reliable public transport while reducing pressure on major roads. The project is also expected to improve connectivity between residential, commercial and employment areas. Further details on the final alignment and implementation schedule are expected as the project planning progresses.
