It serves some of the largest cities and towns in southwestern Bangladesh, including Faridpur, Magura, Jhenaidah, Jessore, and Khulna.

Southwestern Bangladesh is laced with numerous rivers and streams, which results in N7 having the most bridges and culverts of any highway in the national system.

[2] Although sometimes called the Dhaka—Khulna Highway, the city of Dhaka lies across the river and 70 kilometres (43 mi) east of the end of the road.

[3][4][5] Beginning at the ferry terminal, N7 goes southwest for 14 km before it turns southeast and parallels the river as far as the junction with N803 just west of Faridpur.

[1] It makes a three-quarters loop around the north and west sides of Jhenaidah, with N704 splitting off at Arappur and N703 going into the centre of the city, before N7 turns south to Jessore.
