Abstract: This paper will analyse the middle span of the 31m-in-length bridge. The calculation stages undertaken here were to design the form and dimensions using PCI Girder-Type Prestressed Concrete, to determine the prestress force, eccentricity as well as the number of tendons and routes of each cable, and to calculate the resulting stress of the beam cross-section and the resulting loss of prestress forces. There were 4 tendons of prestressed cables for the PCI Girder design, each of which consisted of 19 high quality wires, i. e. uncoated 7 Wire Super Strands ASTM A-416 grade 270 with the cross-section equal to 12.7 mm in width and the ultimate tensile stress by1, 860 Mpa, with a total of 76 strands. The tendon tensioning system implemented was the post-tensioning one where the prestress force was given when the concrete has already achieved the required age. The Bridge of Meureudu City experienced a total prestressed loss by 26.32 %. The tendon route was parabolic with the greatest moments by 7, 556.75 kNm derived from a combination of its own weight, additional dead loads, lane loads, the brake force and wind loads.
