Bengaluru Chennai Expressway Set for Full Completion by Early 2027

The Bengaluru Suburban Railway Project is steadily shaping up as one of the most transformative infrastructure initiatives for the city. With an estimated investment of Rs 23342 crore, the 148 kilometre rail network is designed to serve nearly 19 lakh passengers every day once fully operational. The large scale mobility project aims to ease congestion, improve connectivity and create a seamless urban transport ecosystem across the metropolitan region.

Spread across 57 stations, the project comprises four corridors named Sampige, Mallige, Parijata and Kanaka, collectively branded as Samparka, symbolising connectivity. The network will integrate with 17 Metro stations, 22 railway stations and major bus depots wherever feasible. This integrated approach is expected to reduce dependence on private vehicles and road based public transport, easing pressure on Bengaluru’s heavily burdened road infrastructure.

Officials estimate that once all corridors are operational, the system could help remove nearly 40000 buses from city roads. Around 24 level crossings are set to be eliminated, significantly improving safety and ensuring smoother vehicular movement. The project is being implemented by Rail Infrastructure Development Company Karnataka Limited with a focus on operational efficiency and long term urban planning.

Sustainability has been embedded into the design framework. Stations are being planned with universal accessibility features, solar power installations and rainwater harvesting systems. The suburban rail network is projected to reduce nearly 10 million tonnes of carbon dioxide emissions annually and harvest around 22 million litres of water each year.

A key highlight is the proposed multi level interchange at Yeshwantpur, which will seamlessly connect suburban rail, Metro and Indian Railways services. As Bengaluru continues to expand, the suburban railway project is expected to redefine daily commuting, enhance economic productivity and support balanced development across emerging growth corridors.
