These are cool. I don't know how I missed this thread the first time around.

Here is the Yards Park bridge in Washington, DC. It's part of the Anacostia riverfront.

There are twin pedestrian bridges connecting federal buildings on Independence Avenue. They look a lot better in person.

Here is the Falls Park bridge in Greenville, SC, which was mentioned a few posts up.

Some really cool bridges so far, keep em coming!

This one in Vancouver was always one of my favourites. It crosses 5 lanes of traffic and a railroad track, yet the bushes on either side are so tall you don't even notice you've left the park until you end up on 7th Ave.

This is the view from the middle of the overpass, the first time I went over it I never even knew I had left solid ground.

inFORM studio: bagley pedestrian bridge

american practice inFORM studio has completed the 'bagley pedestrian bridge' located in detroit, michigan. the winning proposal of a competition driven initiative addresses inhabitants of communities located in the southwest of detroit whom have been divided and isolated from a rift generated by highway implementation. this new infrastructure provides a safe means of crossing the congested areas providing an elevated connection to the vehicular bridge which leads to windsor, ontario, canada.

Baltimore Inner Harbor Ped Bridge

I didn't see this posted yet. This could be pretty spectacular.

Inner Harbor bridge proposal leads way in GBC poll

Date: Friday, June 3, 2011, 10:32am EDT - Last Modified: Friday, June 3, 2011, 11:31am EDT Alexander Jackson Staff Reporter - Baltimore Business Journal

A proposal to build a pedestrian bridge across the Inner Harbor is leading the way in an online survey asking Baltimoreans to vote on their favorite idea for redeveloping Rash Field.

Here's the proposed Baltimore bridge. I love the idea. I've always lamented that one of Baltimore's harbor tunnels wasn't built as a suspension bridge instead.

What's the other slash running to the right behind Federal Hill? I like the idea that the bridge might be tied into the hill somehow.

Vertech Limited Bridge, Peeblesshire, United Kingdom
Ninety foot road bridge manufactured from waste plastic

When sending your plastic bottles for recycling, where do you imagine they’ll end up -perhaps as another bottle or even a plastic bag? One innovative Welsh company have just completed a European-first - by turning 50 tonnes of waste plastic into a record 90ft Thermoplastic road bridge suitable for heavy goods vehicles.

So many of the pedestrian bridges shown here seem to be both too expensive, and, show too much of the politician's inclination to "make a monument to me."

In my opinion, the best bridge design was largely worked out by US railroads by the 20s. Those bridges built by the railroads were built to support huge loads, whereas pedestrian bridges would not require such a huge amount of support weight due to the square/cube law. If classic truss systems which can be seen in almost any pre-sixties engineering handbook had a load limit 1/10 of a rail span, the mass needed for the trusses and truss support would require about 1/100th (the square root) the building mass per linear meter.

Keep pedestrian bridges light, under tension, and, free of oscillation harmonics. The simplest way to reduce oscillation is not to suspend the bridge- just mount it on support abutments.

Don't play with curves too much unless they are in the X,Y plane. Curves in the horizontal plane can have pretty complicated downward thrust problems... Build them with cheap materials- some old wooden rail trussels have lasted many decades (creosote replacement needed, of course). Steel tubing, IMO, is pretty cool, too, but, welding is more difficult. If concrete is used, make it pre-streesed, precast and truckable to the site. Stay away from too long spans, because pricing for increasing the spanlength is not linear, but exponential.

Those truss bridges also have a handsome industrial aesthetic. Incidentally, some of the best-looking bridges are stone and concrete arch bridges, but it appears they are too expensive to build anytime in the near future. Le sigh.

The ugliest type of bridge is the highway girder bridge, like this example (which is, incidentally, hardly ever used). What a boondoggle...

Shameless hometown plug, but san antonio has some pretty neat pedestrian bridges:

One of the original River Walk bridges from the '30s. Simple but pretty.

A bridge on the new northern part of the River Walk. It originally connected the towers of the Lone Start brewery (the building in the background)

The Hays Street Bridge, an old car bridge over the railroad on the east side.

excellent thread. there are some amazing pedestrian bridges around the world.

there are two pedestrian bridges under construction in portland right now. well, one pedestrian and one transit-bike-and-pedestrian.

the gibbs street pedestrian bridge will provide much needed access across i-5 and two major avenues to the tram and south waterfront. it's pretty unspectacular.

rendering:


this pic is from last month:



the portland-milwaukie light rail bridge will ... wait for it ... carry the new portland-milwaukie light rail orange line across the willamette, and be closed to vehicular traffic but open to pedestrians and bikes. this bridge, however, looks pretty great. construction on it just started recently, and it's supposed to open in 2015.

renderings:

probably no surprise that cleveland's version goes across a redeveloped old factory!

seems like calatrava set the standard for modern ped bridge style.

It's in the area of Rome where Hadid's MAXXI and Piano's Parco della Musica are, as well as some landmarks remaining from the 1960 Olympics. It seems like they're trying to create an architectural paradise a la Valencia.
