Pedestrian Underpass Feasibility Study June 17, 1997 <br /> East Marietta Street and East Condit Street <br /> repaired area appears in need of additional repair. The south waIl, west of the bridge, has <br /> one section that includes a horizontal crack just above the sidewalk. The crack has water <br /> seeping through the wall. � <br /> In the area of the bridge, a single span thru-plate �rder bridge carrying four tracks of the <br /> Illinois Central Railroad, it was noted that water has seeped down the face of the <br /> abutments from the joint between the bridge deck and back wall. It appears that the � <br /> original waterproofing and/or deck joint in this area has failed_ <br /> It is suggested, should any modifications be made to the underpass, that a structural study <br /> of the noted problems be completed on the underpass prior to any design phase. <br /> A.s noted, there are five foot sidewallcs on both sides. Both sidewaiks are a continuation <br /> of walks from both east and west of the structure as we11 as sidewalks from Lon�view <br /> Place and the Phoenix Park area. <br /> Three aiternates are being considered for improving the existina Condit Street underpass. <br /> Alternate SA <br /> T�rimal l��odification to Underc�ass Structure. Condit Street <br /> As shown in Exhibit J, the width of the existing sidewalk on both sides of the underp�ss <br /> does not meet American Disabilities Act criteria. Also, the sidewalks do not meet width <br /> criteria for bicycle use. The profile of the sidewalk is approximately parallel to the street <br /> profile, thus having a maximum grade of about seven percent. This percent grade is below <br /> the minimum required by ADA, however, there are no landings or handrails to assist <br /> handicapped use. <br /> � Present lighting in the underpass is by overhead lighting mounted on wood poles along the <br /> north side of Condit Street and ornamental light poles along the north side of Longwood <br /> Place west of the railroad. <br /> During site survey work it was noted that, as shown in Exhibit I, there is no fencing or <br /> wall along the east or west right of way line of the Illinois Central Railroad north of <br /> Condit Street. A sidewalk is located behind the north retaining wall west of the railroad <br /> and a well worn path is located behind the north retaining wall east of the ra.ilroad parallel <br /> to Condit Street Several pedestrians were observed crossing the railroad above the • <br /> underpass. <br /> Minimal modifications could be made to the underpass to improve safety.
