The Patikraja Bridge in Banyumas Indonesia is a truss bridge of the Pratt type, measuring 127 meters in length and 5 meters in width. It was built for trains during the Dutch colonial period and is currently being transformed into a public route for automobiles. As an alternate design, the bridge is redesigned with K-type steel trusses. The purpose of this paper is to explore the design of truss bridge including the dimensions of the steel profile that will be used. LRFD (Load Resistance Factor Design) is used in conjunction with SNI 1726:2016 loading (Indonesian National Standard). The profile of the wind bracing was calculated using the 500x200x10x16 and 500x500x25x40 profiles. The 500x500x25x40 H profile is used for the top side bars, diagonal side bars, and side bars. Steel profiles H 450x200x9x14 for the longitudinal girders and H 700x300x13x24 for the transverse girders were used. Bolt connection with bolts measuring 112 inches. The bridge deflection is 36 mm. The dimensions of the plate were determined to be 7x45x0.25m. The bridge's backrest pipe is made of 3 inch pipe. 725x740 mm elastomeric bearing. The slab measures 7 meters wide by 6 meters long. The body of the abutment is 2 meters thick and 8 meters long. The abutments for the pilecaps are 8 m broad and 9 m long. The wing wall measures 5.5 meters in width and 6.75 meters in height. For example, if the foundation on the abutment is 0.5 m in diameter and 10 m in length, there could be up to 18 foundations.
