Client: Chicago Department of Transportation

Location: Chicago, Illinois
Total Cost: $42.5 Million
Project Fee: $125,000
Services Provided:
  • Electrical Engineering
  • Lighting Design

SINGH, as a subconsultant, provided electrical and lighting design for the 41st and 43rd Street Twin Pedestrian Bridges over Lakeshore Drive in Chicago’s Bronzeville community. The 43rd Street Bridge will replace the current structure, built in 1938. 41st Street Bridge will be a new structure joining William Davis Park with the Lakefront Trail in Burnham Park, as well as providing access to the new Oakwood/41st Street Beach.

SINGH’s scope of work includes PS+E document preparation for railing mounted LED lighting design for the pedestrian path, architectural light pole design for supplemental lighting along the path, RGB color changing aesthetic bridge structure lighting, and modifications to Lake Shore Drive highway lighting. SINGH performed photometric computations, voltage drop computations, plan preparation, utility coordination, specifications and cost estimate. The project required the relocation of Metra’s medium voltage overhead transmission lines and communication lines to avoid conflicts with the new 41st Street bridge as well as medium voltage transclosure design for CDOT.
