The bridge at Kushalgarh on the North West Frontier was built by the British in the months leading up to the outbreak of the 1st Afghan War (1839-1842). It replaced a ferry service. The bridge of boats was a vital artery for British forces during all their campaigns in the region, including the 2nd Afghan War (1878-1880).
