| Title | BP Bridge, outline in rebar, May 9, 2003 |
| Description | The path of the BP Bridge was outlined in rebar, or reinforcing bar, which was later cast in concrete. The orange caps atop the rebar spikes were for worker safety. Below the rebar a seam is visible in the preexisting concrete rooftop. Built atop two stories of parking garages and railroad tracks, Millennium Park is one of the largest intensive green roofs in the world. |
