Infrastructure development in Chennai, including Metro Rail construction and storm water drain works, has created various urban challenges. Initial reports highlighted pedestrian safety risks on Arcot Road due to a lack of footpaths and narrowed road space. In Ambattur, subway construction near the railway station faced delays caused by continuous waterlogging, forcing commuters to walk across active tracks.

As development continues, the focus has expanded to include the proposed Global Capability Centre (GCC) corridor in Tamil Nadu, targeting business areas such as Rajiv Gandhi Salai (OMR), Pallavaram-Thoraipakkam Radial Road, and Mount-Poonamallee High Road. To facilitate Chennai Metro Rail phase-2 construction and sewer pipeline repairs, authorities have implemented night-time traffic diversions on the OMR stretch between Tidel Park Junction and Indira Nagar Signal.
