Description
Pont Henri is a single arch bridge dating from the 19th century. It has a span of approximately 10 meters and a width of about 4.5 meters between the parapets. The bridge features ashlar voussoirs that are around 400 millimeters deep. To the west of the arch, there is a blocked relief water hole with a diameter of about 1.5 meters. The structure is built from rubble masonry in local sandstone. The parapet walls are 1 meter high and have rock-faced copings, with the south parapet extending a short distance alongside the road at each end.
