Why it matters
SH 4, Amarkantak–Katghora State Highway, crosses the border between Madhya Pradesh and Chhattisgarh. A state road that runs through more than one state has no single owner — MP PWD and Chhattisgarh PWD each maintain the stretch inside their own state, so which department to contact depends on where along the road you are.
