ERA provided Phase I and II engineering for the removal and replacement of the existing four-span bridge with a three-span PPC Deck Beam bridge supported on solid encased pile bents and integral abutments using Federal Funds. The project included 1600-ft of roadway reconstruction for the geometric roadway improvements, including the addition of concrete curb and gutters, a multi-use path, signalized intersection pedestrian modifications, and an on-structure bike path. The design of the suburban major collector roadway included raising the existing roadway profile to meet hydraulic freeboard clearances, while also bringing the existing vertical curves into compliance with current design criteria. The project also provided the local community with pedestrian and bicycle access to the adjacent forest preserve trail system. Phase I engineering consisted of a Project Development Report (PDR), Bridge Condition Report (BCR), Hydraulic Report, Environmental Studies, Forest Preserve coordination and several public information meetings. Phase II engineering consisted of construction documents, permitting, Plat of Highways (POH), Land Acquisition and Negotiations.
