Trans–Haryana Expressway
The Trans–Haryana Expressway or the Ambala–Narnaul Expressway (NH-152D) is a 227-km long, 6-lane wide greenfield 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. The alignment intersects with 15 National Highways, including NH-9, and several State Highways, including SH6, SH9, SH8, SH11, SH12, SH14, SH10, SH16A, SH20, SH24 and SH26. The area around the expressway is being developed as an industrial corridor, named as the Ambala-Kotputli Economic Corridor. Construction was started in July 2020, and was completed and opened for traffic on 1 August 2022. The industrial corridor consists of four road projects, which have:

 39-km section of NH-152 from Ambala to Ismailabad
 227-km long Ambala-Narnaul Expressway
 14-km section of Narnaul Bypass
 30-km section of NH-148B from Narnaul Bypass to Paniyala Mor (NH-48). Details
Costing ₹5,108 crore, it will have 70 metre right of way, 122 bridges and underpasses and 1,36,000 trees would be planted on either sides is being developed by the National Highways Authority of India (NHAI) under Bharatmala project. Grenfield alignment will reduce the Ismailabad to Narnaul distance by 35 km from the existing 265 km route to 230 km new route. Construction will create 1,500 full-time jobs for 3 years and 120 ongoing jobs will be created for the Toll Plaza staff. To reduce the environmental impact the fly ash will be used from the Tau Devilal Thermal Power Plant at Panipat, Indira Gandhi Super Thermal Power Project at Jhajjar and Rajiv Gandhi Thermal Power Station at Hisar.
