The Narnaul–Ambala Expressway, officially known as the Trans-Haryana Expressway (NH-152D), is a modern six-lane access-controlled highway connecting southern and northern Haryana. Stretching approximately 227 km, it links Narnaul in Mahendragarh district with Gangheri near Ambala, passing through major districts including Charkhi Dadri, Bhiwani, Rohtak, Jind, Kaithal, and Kurukshetra. The expressway significantly reduces travel time while improving connectivity between Rajasthan, Haryana, Punjab, and Chandigarh.
