| Summary: | In order to improve the economy in the Yogyakarta to Bawen area, easy mobility access is needed because of the condition of the contours and the ravines that exist in the access between the two areas. The condition of the different contours is a challenge in making connecting roads, especially in areas that are forced to cross rivers or across ravines. In planning, the line requires several bridge constructions, one of which is the Gladak Mainroad Bridge, which is an option to connect the route to be built to support mobility and easy access. The Gladak Mainroad Bridge is planned to use precast I-Girder sections and pre-stressed concrete structures. However, in reality the extreme slope conditions and sandy soil tend to be obstacles to the construction of the bridge. Therefore, the authors are interested in making an alternative design of the bridge by using a box girder cross section using the Balanced Cantilever Cast In-Situ construction method. In planning alternative designs, a problem arises, namely how to obtain a cross-sectional strength that complies with the applicable regulations for the boundary conditions considered, especially for earthquake loads to build an earthquake-ressistant bridge. In this final project, regulatory references are used in the form of SNI and AASHTO. The results of the design alternative planning carried out are the engineering drawings of the bridge girder and the substructure of the building below.
