The intent of this project is to remove and dispose of an existing steel truss & concrete deck superstructure on Du Lac Road, crossing over Cobbs Lake Creek, and to replace it with a new prefabricated steel girder & steel deck superstructure. To accommodate the new superstructure, the existing reinforced concrete abutments are to be extensively rehabilitated and modified, including new deep foundation elements (caisson piles). Work is required along the approach roadways to accommodate the new structure (excavation, backfilling, restoration, grading, fill, approach guiderail, etc.). Road closure gates and rural roadway entrances, needed to accommodate seasonal road closures due to flooding, are also included in the scope. The preceding is not exhaustive of all Work required under this Contract.
