Karnataka budget: What big projects are planned for Bengaluru? Full infrastructure push explained

Chief Minister Siddaramaiah has announced a series of large infrastructure and governance reforms in the Karnataka Budget aimed at transforming Bengaluru into one of the world’s most liveable cities.

Presenting the 2026-27 Karnataka Budget, Chief Minister Siddaramaiah unveiled a wide-ranging development plan aimed at turning Bengaluru into a global liveable city. The plan includes large investments in roads, metro expansion, water supply, stormwater drainage, governance reforms and traffic management.

The government has already undertaken road and infrastructure development works across the five city corporations of Bengaluru at a total cost of ₹1,255 crore. In addition, white-topping works covering 158 km of road length have been taken up with an investment of ₹1,700 crore to improve durability.

Further strengthening the road network, arterial and sub-arterial road development projects worth ₹1,936 crore have been implemented. Another important mobility project involves transforming the Outer Ring Road (ORR) stretch from Silk Board to KR Puram Metro Station into a global-standard corridor, with an estimated cost of ₹450 crore.

To tackle flooding and improve water management, tenders have been issued for the upgrade of primary stormwater drains and lake development works, estimated at ₹273 crore.

To ensure transparent, citizen-friendly and responsive governance, the state has established the Greater Bengaluru Authority (GBA) along with five city corporations. These civic bodies will also raise funds for development by issuing municipal bonds based on their balance sheets.

The state government has significantly increased financial support for the city. The grant for Bengaluru’s development was raised from ₹3,000 crore to ₹7,000 crore in 2025-26, and the same support will continue in the current year as well.

Over the next three years, the government plans to white-top more than 450 km of roads at a cost of ₹3,000 crore to ensure long-lasting road quality.
At the same time, Bengaluru’s civic bodies will carry out beautification of 175 junctions, upgrade 500 km of footpaths and construct 100 skywalks, using internal resources.
The World Bank-assisted Water Security and Disaster Resilience Programme will also support stormwater drain improvement projects worth about ₹200 crore.

To guide the city’s long-term growth and land use, the government will implement a Revised Master Plan (RMP) 2041 for Bengaluru by the end of 2027. In addition, a comprehensive mobility plan will be prepared within the next six months.

Namma Metro, the second-largest metro rail network in the country, currently operates across 96 km and serves about 10 lakh commuters daily. The government plans to complete an additional 41 km of metro lines during the year, which is expected to benefit around 15 lakh commuters.

A 9-km pedestrian walkway along the metro viaduct and the ORR will also be built at a cost of ₹160 crore, supported by ORRCA.

To provide drinking water to around 1.40 crore residents of Bengaluru, the government is implementing the Cauvery water supply project phases 1–5, delivering 2,225 MLD of water. Under Phase-6, the project will supply an additional 6 TMC of water, with ₹6,939 crore assistance from JICA.

To reduce congestion in the city, land acquisition is underway for the 73-km Bengaluru Business Corridor Phase-1, stretching from Tumakuru Road to Hosur Road. Compensation is being provided to farmers on a priority basis, and the project is expected to be completed within four years.

The government has also approved two tunnel road corridors covering 40 km - the North-South corridor from Hebbal Junction to HSR Layout Silk Board and the East-West corridor from KR Puram to Mysore Road. The ₹40,000 crore project will be implemented under the BOOT model.

In addition, the Bengaluru Development Authority (BDA) will construct a tunnel road and elevated corridor from Hebbal Junction to Mekhri Circle at a cost of ₹2,250 crore.

Another project aimed at easing traffic is the Nelamangala-Tavarekere-Bidadi Intermediate Ring Road, which will be developed using the financial resources of BMRDA.

Beyond Bengaluru, the budget also includes major urban development initiatives across Karnataka. Newly upgraded city corporations in Raichur, Bidar and Hassan will receive ₹200 crore each under Mahatma Gandhi Nagar Vikas Yojana 2.0.

Under the Chief Minister’s Amrut Nagarothana Phase-4 scheme, ₹3,885 crore has been allocated for urban infrastructure development, with ₹500 crore released for the current year.

The government will also introduce a Unified Property Tax system for urban local bodies, integrated with the e-Aasthi software platform.

Sewerage infrastructure projects will also be undertaken in towns such as Anekal, Nelamangala, Doddaballapur, Bhadravati, Devanahalli, Mysuru, and in several towns of the Kalyana Karnataka region including Aland, Afzalpur, Chittapur and Yadgir.

Overall, the 2026-27 urban development budget places strong emphasis on infrastructure expansion, traffic congestion reduction and improved drinking water supply, while strengthening governance and planning systems for Bengaluru and other growing cities in the state.
