Proposals for improving connectivity along the Madhavaram–Nallur stretch are linked to potential changes in taxation on construction materials. According to The Hindu, an elevated corridor on NH5 is likely only if the Tamil Nadu government waives GST for materials used in the project. The report also cites a retired highways department official who argues that, rather than an elevated corridor, building three flyovers could be a better alternative. The coverage presents the GST waiver as a key factor affecting the feasibility of the elevated option, while also highlighting that experts differ on the most suitable infrastructure design. The discussion reflects ongoing planning and deliberations around how to reduce congestion and improve traffic flow in the corridor, with different engineering approaches under consideration depending on cost and policy support. At this stage, the information points to conditional likelihood and competing recommendations rather than a finalized decision or start date for any specific works.
