The BP Pedestrian Bridge is a girder footbridge in the Loop community area of Chicago, Illinois. It spans Columbus Drive to connect Daley Bicentennial Plaza with Millennium Park, both parts of the larger Grant Park. Designed by Pritzker Prize-winning architect Frank Gehry, it opened along with the rest of Millennium Park on July 16, 2004. Gehry had been courted by the city to design the bridge and the neighboring Jay Pritzker Pavilion, and eventually agreed to do so after the Pritzker family funded the Pavilion.

The pedestrian bridge serves as a noise barrier for traffic sounds from Columbus Drive. It is a connecting link between Millennium Park and destinations to the east, such as the nearby lakefront, other parts of Grant Park and a parking garage. BP Bridge uses a concealed box girder design with a concrete base, and its deck is covered by hardwood floor boards. It is designed without handrails, using stainless steel parapets instead. The total length is 935 ft, with a five percent slope on its inclined surfaces that makes it barrier free and accessible to all. Although the bridge closes in winter because ice cannot be safely removed from its wooden walkway, it has received favorable reviews for its design and aesthetics. (Read more...)
