Overview

• BMRCL will add double‑decker flyovers on select stretches to ease future road congestion, a change that increases engineering complexity.
• The redesign is expected to raise the budget by about 5% and demand more land, with one official citing roughly 25% extra for stations and road‑widening.
• Phase 3 spans 44.65 km with 31 elevated stations across two corridors: JP Nagar 4th Phase–Kempapura and Hosahalli–Kadabagere.
• Construction is likely to begin in late 2025 or early 2026 and take about five and a half years once work starts.
• The line is projected to carry about 7.85 lakh daily riders with interchanges to the Green, Purple, Blue, Red and Pink lines, extending service to Magadi Road and the western Outer Ring Road.
