NICTD RR over Galena River Bridge

LaPorte County, Indiana

NICTD wanted to replace the existing single-span box-beam structure over Galena River during a short-duration shutdown of the track. The existing bridge had severe scour undermining of the abutments. American Structurepoint provided a structure alternates cost study to help NICTD decide which type of structure would be most cost effective for this type of replacement. Options included a precast structure and a roll-in superstructure with precast end bents on driven piling. The project included a hydraulic analysis for the structure opening, all permit coordination, and creation of plans and bid specifications for the single-span precast concrete arch replacement structure. No track realignment work was needed.
