The bridge is located 12 km (7.5 mi) south of Herat's old city and downstream or west from Pul-i Pushtu.
The sisters had poultry, so they mixed egg shells with clay and, with much effort, constructed the bridge stronger than steel.
Prior to that construction, Pul-i Malan was the only bridge connecting Herat and Kandahar and was considered important because of that.

The Danish Committee for Aid to Afghan Refugees rebuilt the bridge using concrete and baked bricks, strengthening the foundation and roadway in the process.
