Located in the Maseru District of Lesotho, the road linking Semonkong and Mantsa includes many river crossings, with two of the most spectacular bridges in the world.
The bridges are concrete. The longest bridge is 46m long and the shortest one is 12m long. They are often flooded away in rainy seasons.
The bridges carry the unpaved A5 road, from Semonkong to Mantsa.
