Why it matters
MDR 12, Mulleria–Badiadka District road, crosses the border between Karnataka and Kerala. A state road that runs through more than one state has no single owner — Karnataka PWD and Kerala PWD each maintain the stretch inside their own state, so which department to contact depends on where along the road you are.
