Phase I Studies for Various Projects, Region One, District One
AEG performed a Hydraulic Analysis for Illinois Route 31 over an Unnamed Tributary to the Fox River in McHenry County. The proposed scope of work consisted of the removal and replacement of an existing main culvert and an adjacent relief culvert. This interim improvement will be constructed prior to the ultimate configuration improvement to replace these existing culverts in order to remove load restrictions at this location that are necessary due to damage to the structural integrity of the existing culverts. AEG prepared a Technical Memorandum for inclusion in the Unnamed Tributary (Outlet 23) Hydraulic Report describing the proposed interim improvement hydraulic design.
