Why it matters
SH 72, Sector 1–Kala Amb State Highway, crosses the border between Haryana and Punjab. A state road that runs through more than one state has no single owner — Haryana PWD (B&R) and Punjab PWD (B&R) each maintain the stretch inside their own state, so which department to contact depends on where along the road you are.
