Specifications include, but are not limited to:. The feasibility study also evaluated the potential to further grade separate of one of the railroad lines to eliminate rail congestion at this location. The Illinois Department of Transportation, the City and the railroads were involved with this study. While feasible from an engineering standpoint, the projects were prohibitively expensive with insufficient benefit. So there is no current prospect for these full bridge replacement projects. Furthermore, in the wake of issues with objects falling from the timber bridge onto traffic below, the railroads invested in excess of a million dollars to improve the structure and do not have any plans for replacement of the structure. Given the horizontal and vertical curvature of the roadway, combined with a lack of shoulder space, pedestrian and bicycle travel through the crossing is not currently feasible. However, due to demand and a lack of convenient detours, bicycles have been observed through the underpass and pedestrians have reportedly trespassed along/across the tracks in order to traverse the area. This proposed underpass would remove a key barrier and provide safe access for pedestrian and bicycle travel between downtown Des Plaines and areas west. The project would also provide a regional benefit, removing a barrier in the envisioned 20-mile Northwest Highway Regional Bicycle Corridor connecting six suburban transit-oriented downtown districts with the greater City of Chicago Bike Network. The feasibility study for the Northwest Highway S-Curve Ped-Bike Underpass is anticipated to include but not be limited to: coordination with the railroads and with IDOT; preliminary structural evaluation of the existing railroad structure for a potential culvert underpass, review and topographic survey of the proposed alignment; coordination with utilities with regard to conflicts; evaluation of potential alternatives and estimates of cost for the alternatives. However, the actual scope will be worked out with the selected engineering firm
