This project involves the removal of the existing 136 year-old single track bridge over the Fox River and replacement with two new modern commuter rail bridge structures.  The new structures are 555 LF long with 4 qty 137 LF built up plate girder spans supported by two cast in place abutments and three cast in place piers, all set on H-Piles. The project has two main phases.  Phase 1 included the construction of the new bridge structure, which is complete.  Once rail operations is relocated to the new structure, the existing structure will be diligently removed while rail operations continue.  Phase 2 includes the construction of the second bridge structure in the location of the old bridge.  The project site has unique logistical constraints with the US-20 bridge structure overhead, and power lines running through the work area.  For this reason ICC's experts chose to use a Self Propelled Modular Transporter (SPMT) for the built-up plate girder erection.
