Recently, the construction of a double decker elevated bridge, which is an important component of the third phase of the Nama Metro project in Bangalore, has made new progress. The elevated bridge costs 97 billion Indian rupees, and as the capital of the southern Indian state of Karnataka, Bangalore will inject new energy into its transportation development.

This project was approved by the Cabinet of State earlier this month and plans to build two new lines on the existing structure. A 32.15 kilometer long road extends from the fourth phase of Japnagar to Kempala, running along the western extension of the outer ring road; The other one is 12.5 kilometers long, connecting Kadabajere and Hoshali, and is built along the Magadi Road. After completion, the total length of the elevated bridge will reach 44.65 kilometers. Its uniqueness lies in the fact that the top layer carries subway lines, while the bottom layer carries road traffic, achieving a three-dimensional utilization of transportation resources.

However, the combined viaduct has increased the cost of the Orange Line project in Nama Metro AG by about 5%, and the completion date has also been postponed from 2029 to 2031. In terms of fundraising, according to the agreement between the federal government and the Karnataka state government, the former bears part of the subway costs, the state government contributes half of the cost of the elevated bridge, and the rest is raised by local urban development agencies (10%) and debt financing (40%). Karnataka has allocated INR 40 billion for the Nama Metro project in the 2025-26 budget.

The civil engineering project is expected to start early next year, and the project delivery agency, Bangalore Metro Corporation (BMRC), plans to tender in November to provide four construction packages for the elevated bridge and station. After completion, the Orange Line will serve the growing residential, industrial, educational, and commercial centers of Bangalore. The total project cost is approximately 156 billion rupees, with half expected to be financed through debt and the remaining to be realized through revenue generation, such as selling station naming rights and advertising space. The Orange Line is expected to transport 785000 passengers per day, and the Bangalore metro network will be extended to 222.2 kilometers, making it one of the largest metro systems in India.
