Bengaluru: Work on Metro Phase 3 has started and Red Line, which connects North Bengaluru's Hebbal to South Sarjapur, will help to alleviate traffic congestion and provide the city with better interconnectedness.
Tender for the geotechnical survey has been sought for Rs. 6.86 crores by Bangalore Metro Rail Corporation Limited. The last day for the submission of tenders is 3rd November and, after that, the chosen contractor will have 150 days to do the study.
Key Details of the Red Line Project
Route: Hebbal to Sarjapur
Phase: 3A of Namma Metro expansion
Tender Value: ₹6.86 crore
Study Duration: 150 days
Tender Deadline: November 3, 2025
The officials at BMRCL say that the geotechnical survey is the first step towards construction. This means that the soil and rock along the proposed route will be studied to determine the depth for the pillars for the elevated part and to check the stability of the underground tunnels. While engineers will also select the proper Tunnel Boring Machines (TBMs) on the basis of the data as well as estimate construction costs more accurately.
Expanding Bengaluru’s Metro Network
Presently, the Green, Purple, and Yellow Lines are in operation in different parts of the city. The completion date for the Pink Line (Kalena Agrahara–Nagawara) is set to be in 2026, while the Blue Line (Silk Board–Kempegowda International Airport) will be finished in 2027.
The Red Line will belong to Phase 3A and will therefore contribute to the expansion of the Metro into more areas and also be an important link in the city’s transport network.
What the Red Line Means for Bengaluru
After starting, the Red Line will be a mix of underground and elevated sections, running through the most important residential and commercial zones. Travelers from north to south of Bengaluru are going to experience significantly shorter travel time, major roads will be less congested, and last-mile connectivity will be improved for the hundreds of thousands of daily commuters.
Now, that the Red Line is officially in motion, Bengaluru’s dream of a seamless Metro network connecting every corner of the city is one step closer to reality.
