This $70 million project along Metra’s UPRR North line entails the reconstruction of 11 railroad bridge structures and the construction of Metra’s Ravenswood Station. After performing design work through an open-ended contract with Metra, Benesch was enlisted to provide Phase III construction management services for the 100+ year-old structures on this same line.
This project involved extensive coordination with the Union Pacific Railroad, Chicago Department of Emergency Management, and local businesses and residents. The staging concept for the bridges involved keeping two tracks in service at all times with the new tracks relocated to the extreme edges of the existing right-of-way. Additionally, constructing the commuter pedestrian tunnel at Metra’s Ravenswood Station while maintaining rail traffic necessitated innovative construction staging in order to maintain operations and reduce impacts to commuters and the motoring public. One of the solutions to keep two tracks in service at all times involved an extensive sheet piling system, which was designed to facilitate staged construction.
