Why it matters
SH 27, Palakkad–Anaimalai State Highway, crosses the border between Kerala and Tamil Nadu. A state road that runs through more than one state has no single owner — Kerala PWD and TN Highways each maintain the stretch inside their own state, so which department to contact depends on where along the road you are.
