CMRL's Revised Phase II Corridor 5 Alignment Near Koyambedu To Enable Straighter Route

The Chennai Metro Rail Limited’s (CMRL) revised alignment for Corridor 5 of its Phase II project near Koyambedu has begun to take shape on the ground, according to a Times of India report.

Initially, the Madhavaram–Sholinganallur corridor curved after VR Mall to connect Kendriya Vidyalaya, cross the DMDK party office, and then headed towards Koyambedu.

However, the shifting of long-distance bus services from the Chennai Moffusil Bus Terminus (CMBT) to Kilambakkam significantly reduced projected ridership on this section.

In response, CMRL opted for a straighter route directly linking Kendriya Vidyalaya to Koyambedu, dropping the proposed Kaliamman Koil Street station and eliminating the earlier curve.

The realignment brings the new viaduct closer to Corridor 2, requiring substation modifications. The double-decker viaduct design for Koyambedu remains unchanged, with the completion itargeted for June 2026.

The revised alignment has also allowed the state highways department to expedite the long-awaited Rs 18 crore pedestrian skywalk project at the intersection of Jawaharlal Nehru Road and Poonamallee High Road.
