The National Highway Authority of India developed this stretch as part of its national highways development project. The GMR group which has constructed the expressway is the concessionaire for the collection of toll and the maintenance of the expressway.
Earlier the Ambala Chandigarh section of the highway was a two lane stretch, but with one of the highest traffic densities in the country with traffic coming in from the adjoining states of Punjab, Haryana, Himachal and Delhi, it was always very crowded. The construction of the modern four lane expressway over several bridges and flyovers has reduced the travelling time considerably. As it connects the industrial cities the commerce in the area has also received a boost.
The expressway is at the beginning stretch of the NH 22 which connects the town of Ambala in Haryana and Chandigarh. Chandigarh is the capital of Punjab and Haryana and the most important industrial hub of the region. Ambala is on the border of Punjab and Haryana and has one of the main railway junctions of the northern railway zone. Due to its geographical location the town is an important transit for traffic coming from the capital Delhi and bound for the popular tourist hill towns of Himachal such as Shimla, Chail and Kasauni. The roadways are the lifeline for the hilly and mountainous state of Himachal and NH 22 and NH 21, which connects Chandigarh to Manali, are the major roads which connect the state to the plains.
