CDOT Division Street Reconstruction

Chicago, Illinois

DB Sterlin provided civil and structural engineering services for the Phase II design of bridge replacements and roadway improvements on Division Street from east of the Kennedy Expressway to Cleveland Avenue.  Civil engineering services included maintenance of traffic design, existing utility base-mapping, creation of 3-D model for existing and proposed sewer, utility coordination, existing and proposed signing plans, and ADA ramp and driveway grading design.  Maintenance of traffic design included several stages to accommodate the bridge replacement, including a temporary run-around onto temporary bridges set adjacent to the existing bridges to be replaced.  Major existing utilities included active ComEd and Water tunnels, an abandoned Water tunnel, large-diameter City of Chicago and MWRD sewers and junction structures, and relocation of an existing sewer outfall at the river bridge. DB Sterlin also provided coordination with ComEd for installation of new lighting service connections, modification of existing service connections, and relocation of existing utility poles and modification of overhead facility heights to eliminate conflicts with proposed lighting. Coordination with AT&T and Comcast was also required to adjust overhead lines and remove/relocate utility poles in conflict with the proposed work.

The proposed improvements will construct new tied-arch bridge structures on Division Street over the North Branch of the Chicago River and the North Branch Canal.  The project also includes roadway improvements along Division Street and Elston Avenue, including roadway widening, new sewers, and new lighting and traffic signals.
