The completion of the 4-km elevated stretch between St. Thomas Mount and Adambakkam in the Chennai Metro Rail (CMRL) phase II project is anticipated in 2027. This stretch is part of corridor 5, one of the three corridors in the project, which aims to enhance transportation across the city.

CMRL officials emphasise the importance of promptly finishing this stretch since it will serve a large number of people in the area. However, constructing this short stretch poses challenges due to narrow and congested roads, as well as the presence of structures in close proximity to the alignment.

The construction efforts will be coordinated with the Southern Railway, as the proposed extension line of the Mass Rapid Transit System (MRTS) and the Metro Rail line share a common alignment for this segment. Although it is expected to be time-consuming, the authorities aim to complete the construction within the next four years.

Among the elevated stretches in the phase II project, the section from Poonamallee to Porur will be the first to be opened to the public after three years. Conversely, the St. Thomas Mount to Adambakkam stretch will be the last to be completed, with the target year being 2027.
