Norfolk Southern


Bowman, Barrett & Associates Inc.

This project included the construction of two new three-span railroad bridges and approach embankments to replace the existing bridge carrying two Norfolk Southern Railway tracks over the East Arm of the Little Calumet River.

The new bridges are ballasted deck-girder type with piers and abutments founded on driven piles. They were constructed alongside the existing bridge which was removed upon completion of the project. The existing tracks and bridge remained in service throughout construction, with a 79-mph maximum timetable track speed.
The new abutment construction required that the existing tracks be supported by temporary earth retention walls tied through the track embankment. Portions of the earth retention system remain in place as permanent walls. The existing track embankment was widened and the tracks were shifted to meet the new bridge locations.
ICC was also responsible for all ancillary work including erosion control, temporary causeways, temporary access roads, cofferdams, temporary shoring and permanent seeding and tree planting.
