The Bangalore Metro Rail Corporation Limited (BMRCL) has begun geotechnical investigations along Sarjapur Road for the proposed 37.8-km Bengaluru Metro Phase 3A corridor, also known as the Red Line, which is planned to connect Sarjapur in southeast Bengaluru with Hebbal in the north.

The investigation will assess the characteristics of the soil and underlying rock formations along the proposed alignment before construction work begins. The findings will help engineers evaluate ground conditions and determine the technical requirements for building the elevated and underground sections of the metro corridor, according to the BMRCL officials.
