The Yibna Bridge is a Mamluk arch bridge near Yibna, which crosses the river Nahal Sorek (formerly known as Nahr Rubin, or Wadi al-Tahuna). It is currently used by Route 410 to Rehovot. It is also known as the Jumping Bridge due to a bump in the middle of the bridge which causes cars to jump if speeding.[1]

History

The downstream-facing side of the bridge in 2010.

The bridge was one in a series of bridges built by Sultan Baybars in Egypt and Palestine. It was first studied in modern times by Charles Simon Clermont-Ganneau, who noted that an Arabic chronicle had referred to the construction by Beibars in 672 AH of two bridges build of a significant nature “in the neighbourhood of Ramleh”. The chief purpose of these bridges was to ease communication for his armies between Egypt and northern Syria.[2] The second of these two bridges is thought to be the Jisr Jindas.[2]

According to Clermont-Ganneau, the bridge was built in 671-672 AH (1273-1274).[3] The Archaeology of Society in the Holy Land cites the completion date as 1273.[4]

Max van Berchem, who examined it in the late 19th century, found that the bridge contained large amount of reused Crusader masonry, some of which carried mason´s marks.[5]

Description

The bridge is 48 meters long, and 11.5 meters wide.[6] It comprises three arches, two central piers with triangular upstream-facing cutwaters and downstream-facing buttresses with sloping cills.[7]

It is very similar in design to the more well-known Jisr Jindas, apart from the width of the piers.[7] The bridge has a more than 2:1 arch-span to pier-width ratio versus approximately 1:1 at Jisr Jindas.[7]

The bridge does not contain any decoration or inscriptions, similar to that found on Jisr Jindas. However, according to Andrew Petersen there is "a possible inscription or signature" on a stone at the south end.[7]
