V3 provided construction management services for the replacement of the 27th Street pedestrian bridge serving the station platform on the Metra Electric Line. The work included the removal of the existing substructure and superstructure and installation of a prefabricated steel bridge on newly installed foundations. The high voltage catenary lines, which were attached to the existing bridge, and signal coordination were two of the complications involved in this bridge replacement project. Adding foundations between active train tracks also provided a unique challenge. To minimize station closures, work was completed during night-time and weekend hours.
