Over 120 meters, this viaduct spans the Semois at a height of more than 40 meters. This bridge is one of the emblematic places of the Belgian TV series "La Trêve" broadcast on RTBF and France 2.

The "Conques" viaduct is located 1 km from the village center of Herbeumont.
Construction of the viaduct began in 1902 by the Chagnaud and Cox companies. The viaduct was the first completed structure for railway line 163a.
It took two years to build and is said to have used 9 million bricks. The brick construction of graceful, high arches, the central one reaching almost 40 meters above the Semois, is truly impressive. Although construction was completed in 1904, it would be another 10 years before the first trains (under German occupation) rolled over the viaduct!
