<p align="justify">One of the problems at Tanjung Perak Port in Surabaya is the congestion of goods. This congestion was caused by the rapid development of container flow at the Tanjung Perak Port as a trading center in the Eastern Indonesia Region (KIT) which was not followed by sufficient port supporting infrastructure. Congestion occurs when many trucks simultaneously haul goods or containers from the depot to the harbor, which in turn fill the road over its capacity. Due to the congestion, the operational cost of trucking has increased. This problem can be solved by procuring freight train bridge as a transportation facility that can be built through the sea side. One of the train lines to be built is one that goes from the TPS to Kalianak station. The author of this final project will design the super-structures and sub-structures of the freight train bridge that connects the TPS and Kalianak stations mentioned aboves. <br /> <br /> <br /> The super-structure of freight train bridge is a steel bridge designed using the Load and Resistance Factor Design (LRFD) method. The design of the bridge’s structure includes the design of steel frame combined with arch, bolt joints connection, welded joints connection, hollow concrete pier, and solid concrete pier. The design process consists of loading, modeling, and detailed design. The super-structure modeling process is performed using SAP2000 for bridge frames, CSI Column for hollow bridge pier, and PCA Column for solid bridge pier. The results obtained from the design processes are the configuration and profile for the cross section of the bridge’s truss structure, the number and configuration of the bolts for the bolt type connection, the configuration and the welding length for the weld type connection, the pier cross-section dimension, and the pier reinforcement detail. <br /> <br /> <br /> <br /> The designed sub-structure is a deep pile foundation with a pile cap. Sub-structures design includes analysis of the axial bearing capacity of a single pile, lateral bearing capacity of a single pile, pile group analysis, detailed design of pile caps, and pile head settlement analysis. The pile foundation is designed using the Allowable Stress Design (ASD) method based on the load obtained from analysis result of super-structure for service load combinations. The modeling of the bridge <br /> <br /> foundation was performed using Ensoft L-Pile for lateral load modeling on a single pile and Ensoft G-Pile for pile group modeling based on the deflection constraints. After obtaining the configuration and the number of piles, the design is done at the pile cap dimensions and flexural reinforcement using manual calculations and the assistance of SAFE software to help confirm the calculations done manually. The analysis of soil settlement is perfomed with limits that was based on the bridge operational specifications. <p align="justify">
