When the last two stretches connecting Anna Salai and north Chennai are opened in January,  Chennai Metro plan to extend its services till 11 p.m. This is to cater to the passengers using metro to get to the airport. CMRL expects more passengers after the extension in January and is also planning to increase the frequency from seven to 5 minutesduring peak hours.

The CMRL extension in late January will have 2 stretches – Washermenpet to Chennai Central (3.4 km) and AG-DMS to Chennai Central (4.1 km) – thrown open to the public

“Apart from that, we expect many more to start using our services when these two stretches would become operational by January. If there is a significant increase in traffic, we could even increase the services by an hour-and-a-half; but that will be decided later”, The Hindu reported, quoting a CMRL official.

When the 2 new Chennai Metro stretches are opened, the commuters can travel directly from Washermenpet to Chennai airport.
