World's Most Spectacular Pedestrian Bridges
BP Bridge, Millennium Park, Chicago
Get an overview of Chicago's most impressive architecture, not to mention Lake Michigan, when you set out from the brushed-steel Jay Pritzker Pavilion and amble along Frank Gehry's 925-foot-long bridge above Columbus Drive. Clad in shiny lizard-skin-patterned steel and paid for by its oil-company namesake, the overpass's only shortcoming is that it doesn't make it all the way to the water's edge—you're left to fend for yourself on traffic-filled Lakeshore Drive.
Companion Bridge: An ultra-skinny minimalist footbridge, designed by Renzo Piano, leads from Millennium Park to the architect's new wing of the Art Institute of Chicago.
