HBM Engineering Group, LLC played a crucial role in the structural design of approach structures and stairs for the 41st Street Pedestrian Bridge project, undertaken in collaboration with AECOM and commissioned by the Chicago Department of Transportation (CDOT). This pedestrian bridge project serves to connect the Bronzeville community to the Lakefront, spanning Lake Shore Drive and active railroad tracks. It links the new William Davis Park in Oakland with the Lakefront Trail in Burnham Park and provides access to the Oakwood Beach area.

Key Aspects of the Project:

1. Pedestrian Bridge Design: The project involved the design and construction of a pedestrian bridge spanning a significant distance and crossing over Lake Shore Drive and active rail lines. The bridge’s primary purpose was to provide a safe and accessible passage for pedestrians and cyclists between the Bronzeville neighborhood and the 41st Street Beach.

2. Approach Structures: The approach structures included the outer portions of the bridge that traverse the recreational parks on both sides of Lake Shore Drive and the railway tracks. These approach structures were integral to the bridge’s overall design and functionality.

Project Highlights:

The 41st Street Pedestrian Bridge project was characterized by its remarkable accomplishments and engineering feats. Overcoming the challenge of spanning 1,470 feet over active rail lines, catenary wires, and all eight lanes of Lake Shore Drive was a testament to the project’s innovative design and careful execution.

One of the most striking elements of the project was the bridge’s twisting approaches, forming a giant ‘S’ as it connected the Park Crescent community in Bronzeville to the 41st Street Beach. The inclined, fabricated steel arches that supported the bridge were not only functional but also added an artistic and aesthetic dimension to the project.
