Why it matters
SH 85, Rayakottai–Attibele State Highway, crosses the border between Tamil Nadu and Karnataka. A state road that runs through more than one state has no single owner — TN Highways and Karnataka PWD each maintain the stretch inside their own state, so which department to contact depends on where along the road you are.
