Bengaluru's Namma Metro system is set to undergo a significant expansion with the detailed project report (DPR) being prepared and readied for the Sarjapur-Hebbal line. Estimated at Rs 16,543 crore, including land acquisition charges, the 37-km line is outlined in the Comprehensive Mobility Plan 2020, and is expected to ease travel for those commuting to and from tech zones.

The alignment involves an elevated corridor near the IT corridor in Sarjapur, transitioning underground at Koramangala and emerging on Ballari Road with elevated stations at Ganganagar and Hebbal. The new line will be interlinked with the Blue, Pink, Purple, and Phase-III lines at four key points.

At Iblur, it connects with the Blue Line heading from Central Silk Board to Kempegowda International Airport. At Dairy Circle, the station links with the Pink Line, offering connectivity towards Bannerghatta Road or MG Road, and near KR Circle, it integrates with the operational Sir M Visvesvaraya station of the Purple Line. Close to Hebbal, it connects with the Blue Line, Phase III (Kempapura to JP Nagar), and the suburban rail station (Baiyappanahalli to Chikkabanavara).

The Sarjapur-Hebbal line is slated to have seven stations, including Basaveshwara Circle, Bengaluru Golf Course, Palace Guttahalli, Mehkri Circle, Veterinary College, Ganganagar, and Hebbal.
