It's not exactly an architectural marvel, but it's apparently the longest purpose-built pedestrian bridge in N. America. It was constructed over an existing dam on the Arkansas River and lights up and night. We walked across it while visiting family in AR a few years back and it was a pretty cool experience.

There is also an old railroad bridge next to the Clinton Library that was recently converted to a pedestrian bridge:

We need someone to post some photos of the "Purple People Pedestrian Bridge" in Cincinnati, along with the fantastic curved suspension pedestrian bridge in Greenville, SC!

The Old Salem Timber Pedestrian Bridge in Winston-Salem, N.C.

Built through a partnership between Old Salem, the North Carolina Department of Transportation and the City of Winston-Salem. The bridge reflects the unique culture and historic character of Winston-Salem. The award winning bridge is a 120-foot modified Burr-arch truss bridge designed by David Fischetti and built using skilled craftsmen utilizing 19th century building techniques. The timbers used are reclaimed from a demolished fertilizer plant in Chesapeake, the 1886 Champion Paper Mill in Canton and 260 year-old timbers pulled from the cotton docks of Savannah Harbor. A Burr-arch truss was a bridge Moravian settlers would have built in the early 1800s as Winston-Salem grew. Burr-arch trussed bridges were built near other Moravian cities in Pennsylvania. Theodore Burr (1771-1822) obtained a patent for this bridge style in 1817. The first Burr-arch bridge was built across the Hudson River in New York in 1804. The Old Salem Timber Pedestrian Bridge was built in December 1998 at a cost of $1,950,910.

It connects a visitor center designed by architect Robert Venturi to the Museum of Early Southern Decorative Arts and the Old Salem National Landmark District (Winston-Salem's lower downtown), developed in the mid-1700s. The steps and ramps connect to the Winston-Salem Pedestrian Walkway System of bike and walking paths on the Visitor's Center side.

I've been on that bridge... it's railfan central, packed with balding bespectacled men carrying huge cameras.

It's a cool bridge, and I love the re-use of an older structure, but the fact that one end is in a private building is a point against it, since you can't use the bridge outside of Union Station's operating hours.

Two more nice ones in the greater Phoenix area:

This small pedestrian bridge over a canal in downtown Scottsdale. It was designed by the legendary (and loony) Palao Soleri:

Clever. I like how the series of ramps allows for smooth movement between the elevated plazas and the quays on both sides.

After revisiting this thread, the following pedestrian bridge is by far my favorite one posted so far. I love how it's carrying greenery and integrates well into the street scape with the shops nestled underneath.

here's my favorite pedestrian bridge in NYC.
