Give us a green patch
I propose to the Cantonment Authority, The City Corporation, The Railway and all other relevant authorities involved in town planning to convert the unused land-- starting from the turning of the Kamal Ataturk Road to the Airport Road and ending at the Cantonment Staff Road Railway crossing--- into a park for the general public.
I've noticed in China and many other places that they don't have unusually large parks, sometimes it's just a strip wide enough for people to complete a circuit of walking. Breathing spaces are required to free up the clogged city arteries.
If there were refreshment stands on either side, and an artificial lake , it would be a great place for people of Banani, Gulshan, Mohakhali and Cantonment areas to come for recreation and evening walks.
