Padalarang Fly Over is an alternative that is used to overcome problems related to performance at the Padalarang intersection. This fly over connects the Kota Baru Parahyangan access road with the Padalarang toll gate, thereby reducing vehicle conflicts that occur at intersections. Padalarang Fly Over has a width of 24.24 meters and a total length of 292 meters, consisting of 6 bridge spans supported by 5 pillars and 2 abutments. This final project discusses the design of foundations that can withstand the loading of bridge structures and retaining walls that are able to hold the soil as needed safely. The cantilever retaining wall is used to hold the embankment of the approach road at points A1 and A2 at 6.378 meters and 4.628 meters. In the wall design, a design with a wall height of 7.778 meters and 6.028 meters and a plate width of 5.445 meters and 4.22 meters are used. The bored pile foundation is used with a diameter of 1 meter and 1.2 meters with a tip depth of 19-26 meters. In the foundation design, an analysis is carried out on the single axial compression bearing capacity, single axial tensile bearing capacity, lateral bearing capacity using LPILE software, pile group bearing capacity using Ensoft GROUP software, and foundation settlement.
