Description 

1895 bridge continues to carry heavy traffic today on Lake Shore Drive (US 41) and the Lakefront Trail. Originally built just after World's Columbian Exposition, still retains many original or reproduced decorative elements patterned after those at the exposition - lampposts, balustrade railings, and pedestals that once supported elk sculptures.

Boat traffic under the bridge, to and from the 59th Street Harbor, is controlled by a traffic signal.

Major 1995 rebuild made structural repairs, and re-created some decorative elements. 2004 rehab added a north approach span over a new pedestrian path, and reduced roadway width from 6 lanes to 5 - 3 northbound and 2 southbound, with a new concrete median.
