Here are some possibilities of moving across parts of the city, while the issue gets sorted out:
1. Check the distance to the nearest route where share autos – mini vans – operate. You can get one somewhere close in T.Nagar, Valluvar Kottam, Loyola College, Nungambakkam on College Road, Luz-Mylapore, Inner Ring Road near Ashok Nagar, Tirumangalam, Vadapalani junction, Mogappair, and Velachery-St. Thomas Mount.
2. Use the Chennai Metro if you are going from a point close-by from the limited service, to Kilpauk, Anna Nagar, Tirumangalam, Koyambedu CMBT bus stand, Vadapalani, Ashok Nagar, St. Thomas Mount, Nanganallur and airport.
3. Ola and Uber had regular operations since morning, and it should be possible to get a cab, including share rides. Try Ola Auto and you just may be lucky.
4. Suburban/MRTS trains are an option touching Central, Velachery, Tambaram, and other regular points ranging from Chengalpattu to Gummidipoondi. Download the UTS app and Rs.100 to it, to go paperless (e-ticket) on the Beach-Tambaram route.
5. For inter-city movements, check out an app like Bla Bla Car, taking care to check out the record of people offering rides. Caveat emptor: Do not use this option if you are doubtful, or if you think you carry a higher risk, like a woman travelling alone.
6. Autorickshaws continue to operate, but you need good negotiating skills and knowledge of distances to avoid being fleeced.
