Ha haa hope you didn’t think about the famed sandwich shops, these are the Underpasses below the railway tracks or the pedestrian ones in the main roads.

Chennai has quite a few especially connecting the suburbs which are across the Chennai – Chengelpet railway track and needs a few more on the Chennai – Thiruvallur or Chennai – Ennore direction.

The neighbouring Bangalore / Bengalooru is planning to patent their new technology to construct underpasses in main arterial roads for pedestrians. I hope we follow the idea of mooting more pedestrian subways here in Chennai too.
