Abstract

Pokoh and Jurang Gempal bridge are the bridges that are located on Wonogiri – Ngadirojo roads crossing over Bengawan Solo river connecting Wonogiri Regency and Ponorogo Regency/Pacitan Regency. But in the past 10 years, only one bridge operates and that is Pokoh Bridge. This is caused by the condition of Jurang Gempal Bridge that is no longer adequate since it was built in the colonial era, some parts of the construction aren’t function properly. With only one bridge that is operating, it oftenly lead to a high traffic density on traffic hours. Thus, the re-operating of Jurang Gempal Bridge can be the solution of this traffic density problem that occurred. However, there is a need to do a total change on the bridge construction by seeing the existing condition and the age of the bridge that is already too old. Jurang Gempal Bridge was planned to be located in the existing location that is 2x60 meter in bridge length. The upper structure of this bridge is using steel frame that is 9.0 meter in width (2x3.5 meter vehicle floor and 2x1.0 meter sidewalk) and 6.0 meter in height. Meanwhile, the sub-structure of this bridge is using an abutment that the height is 7.0 meter and a pier that is 9.0 meter in height. The hard soil that is positioned in 10 meter depth is the kind of a sand soil so the Bored Pile is used as the foundation of this Jurang Gempal Bridge.
