Summary
Kaskaskia Engineering Group, LLC (KEG) was a subconsultant to Kimley-Horn and Associates, Inc. for the design of a new pedestrian bridge over I-35W in Minneapolis, Minnesota.
Project
KEG was responsible for the design and plan development of the substructure elements and retaining walls associated with the new pedestrian bridge. The existing structure consists of a 3-span cast-in-place concrete structure. The new structure consists of a 200-foot simple-span truss structure supported by high-wall abutments (Parapet Style per MnDOT) founded on steel H-piles.
KEG was tasked with the design and plan development for the abutments, along with the adjacent cast-in-place concrete retaining walls. Special attention was required to effectively tie in the cast-in-place concrete retaining walls with the adjacent MSE walls. In addition to this coordination, special architectural finishes were desired and detailed for all cast-in-place concrete.
