Mound Road 1 Spring Creek{Middie} Bridge{Currentty under construction} <br /> Center Street/ Stevens Creek Bridge <br /> Meadawlark Bridge <br /> Taylor Raad Bridge (Currently being designed far replacement in 2020) <br /> Grove Road Bridge <br /> Garfield Avenue Bridge/Illinois Central Railroad Yard <br /> Garfield Avenue 122°� Street Bridge <br /> Country Club/Lake Decatur Bridge <br /> BACKGROUNTJ►: <br /> City staff canducts routine bridge inspections of 29 bridges throughout the City. Bridge inspections <br /> are completed within guide�ines set by the Iliznois Department of Transportation{ID{�T) and the <br /> Federal Highway Administration (FHWA). The rautine inspections can lead to findings that require <br /> a more detailed review, structural analysis, and/or repair. <br /> West Mound Road Bridge <br /> During the inspection of the West Mound Road Bridge over Stevens Creek, significant spalling, <br /> delaminatian and cracking was found on the Northeast pier{see phota sheet in Appendix A),the pier <br /> has deteriorated significantly from previous inspections. Under the National Bridge Inspection <br /> System(NBIS} guidelines required by the Federal Nighway Administratian,the new findings <br /> produced a substructure rating of"5" (Fair Candition) on a scale of Q-9 (O=Required Closure, <br /> R=New}. While the overall condition of the West Mound Road Bridge is in goad condition with new <br /> beams and deck being replaced in 2007. The piers need ta be ir►spected and repaired to preserve the <br /> structure. The bridge is currently safe far traffic with no restrictians. The amount af pier repair is <br /> unknown until AECOM's review is completed. <br /> Grove Road Bridge <br /> The Grove Road Bridge over the Sand Creek Arm af Lake Decatur has significant pack rust on the <br /> outer I-beams and a severely delaminated concrete deck. Inspections also faund the rocker bearings <br /> to be over rotated {see phata sheet in Appendix A}. Under the Natianai Bridge Inspection Systern <br /> (NBIS) guidelines required by the Federal Highway Administration, the new findings of the <br /> superstructure praduced a superstructure rating of"5" (Fair Condition) on a scaie of 0-9 (O=Required <br /> Closure, 9=New). The bridge's deck conditian rating continues to be a 3 {Serious Condition). While <br /> the overail condition of the Grove Road Bridge is in fair candition and the bridge is currently safe for <br /> traffic with no restrictions, it is necessary to review and plan for rehabilitation ar replacement of the <br /> structure in the future. The estimated cast and timing of required wark is unknown pending <br /> AECOM's review. <br /> AECOM Technical Services <br /> AECCIM is a local engineering firrn that specializes in bridge engineering. AEC4M has completed <br /> rnany successful bridge projects for the City. Since AEC4M is local and farniliar with each <br /> structure, City staff approached them to perform these structure reviews. <br /> Engineering Services Agrecments <br /> West Mound Road Pier Repair: <br /> The design services are to prepare constructian drawings and abtain approval from the Illinazs <br /> Depart!ment of Transpartation(IDOT)ta perfarm the bridge canstruction wark possibly in 2020. The <br /> Design Services Agreement will include the fallowing services: <br />
