The Trans–Haryana Expressway or the Ambala–Narnaul Expressway (NH-152D) is a 227-km long, 6-lane wide access-controlled expressway, connecting the cities of Ambala and Narnaul in the state of Haryana. The expressway connects Gangheri village (on NH-152) in Kurukshetra district (near Ismailabad) with Surana village on Narnaul Bypass (NH-148B) in Mahendragarh district. It passes via Kaul, Pundri, Assandh, Dhatrath, Kalanaur, Charkhi Dadri and Kanina. It will reduce the distance from Chandigarh to Delhi, Narnaul, and Jaipur, thus decongesting NH-44 and NH-48.
