Mound Road/Spring Creek(Middle) Bridge (Currently under construction) Center Street/ Stevens Creek Bridge Meadowlark Bridge Taylor Road Bridge (Currently being designed for replacement in 2020) Grove Road Bridge Garfield Avenue Bridge/Illinois Central Railroad Yard Garfield Avenue/22°d Street Bridge Country Club/Lake Decatur Bridge BACKGROUND: City staff conducts routine bridge inspections of 29 bridges throughout the City. Bridge inspections are completed within guidelines set by the Illinois Department of Transportation(IDOT) and the Federal Highway Administration (FHWA). The routine inspections can lead to findings that require a more detailed review, structural analysis, and/or repair. West Mound Road Bridge During the inspection of the West Mound Road Bridge over Stevens Creek, significant spalling, delamination and cracking was found on the Northeast pier(see photo sheet in Appendix A), the pier has deteriorated significantly from previous inspections. Under the National Bridge Inspection System (NBIS) guidelines required by the Federal Highway Administration, the new findings produced a substructure rating of"5" (Fair Condition) on a scale of 0-9 (O=Required Closure, 9=New). While the overall condition of the West Mound Road Bridge is in good condition with new beams and deck being replaced in 2007. The piers need to be inspected and repaired to preserve the structure. The bridge is currently safe for traffic with no restrictions. The amount of pier repair is unknown until AECOM's review is completed. Grove Road Bridge The Grove Road Bridge over the Sand Creek Arm of Lake Decatur has significant pack rust on the outer I-beams and a severely delaminated concrete deck. Inspections also found the rocker bearings to be over rotated (see photo sheet in Appendix A). Under the National Bridge Inspection System (NBIS) guidelines required by the Federal Highway Administration, the new findings of the superstructure produced a superstructure rating of"5" (Fair Condition) on a scale of 0-9 (O=Required Closure, 9=New). The bridge's deck condition rating continues to be a 3 (Serious Condition). While the overall condition of the Grove Road Bridge is in fair condition and the bridge is currently safe for traffic with no restrictions, it is necessary to review and plan for rehabilitation or replacement of the structure in the future. The estimated cost and timing of required work is unknown pending AECOM's review. AECOM Technical Services AECOM is a local engineering firm that specializes in bridge engineering. AECOM has completed many successful bridge projects for the City. Since AECOM is local and familiar with each structure, City staff approached them to perform these structure reviews. Engineering Services Agreements West Mound Road Pier Repair: The design services are to prepare construction drawings and obtain approval from the Illinois Department of Transportation(IDOT) to perform the bridge construction work possibly in 2020. The Design Services Agreement will include the following services:
