The new structure included a seven span steel plate girder structure with a reinforced concrete deck.  In addition to the structure replacement, an existing 8’ by 8’ box culvert carrying IL Route 89 over a tributary to Crow Creek was extended on both ends to accommodate the widened roadway design.

KEG personnel performed on-site inspection, including supervision, engineering layout, field inspection of materials, maintenance of records and documentation, and quality assurance. 

KEG staff worked with BNSF Railroad workforces to ensure safety measures were followed per their requirements. KEG also worked with the IDOT Resident Engineer in order to complete this project on a timely basis in accordance with IDOT’s Standard Specifications for Road and Bridge Construction.
