Impressive Pedestrian Bridges

Plans change. I gamble when I choose to mull over a thought and allow it to percolate in my mind. Sometimes the delay results in a better article. Other times, ideas not acted upon decisively will be overtaken by events.

Loyal reader "Rhodent" and I were communicating by email about a potential offshoot of "NOT as the Crow Flies." The contest would have focused on the greatest time or distance differences between walking and driving to a common point, where walking would have provided a distinct advantage. Ariel Dybner posted a comment just as we were structuring the query.

Ariel found a location in Great Smoky Mountains National Park on the "one-way twisty Rich Mountain Road out of Cades Cove." The drive would last 1 hour and 23 minutes. The walk would take 21 seconds. Checkmate. Abundant kudos to Ariel, and well played, and for being prescient enough to claim victory before we ever began. Now it’s back to the drawing board for 12MC though.

I decided to keep the pedestrians and ditch the automobiles. Where are places that motorized vehicles cannot go? Trails, certainly, although I’m on a bridge fixation at the moment. I’ll focus on some impressive pedestrian-only bridges, also commonly known as footbridges.


Notice that I didn’t use the title "longest" pedestrian bridges. Longest is surprisingly subjective and it abuts several definitional issues that I’m choosing to deflect. If one simply must put a fence around the topic then I guess Guinness World Records would be suitable: "On 3 October 2009, the 2.06-km (6,767-ft, or 1.28-mile) Poughkeepsie Bridge (also known as the Walkway Over the Hudson State National Park) in New York, USA, was re-opened to the public as the world’s longest pedestrian bridge. Hornibrook Bridge across Bramble Bay in Queensland, Australia, was longer but demolition started in the summer of 2010."

Let’s go there.

Walkway Over the Hudson; Poughkeepsie, New York, USA

Guinness mentioned the salient points. I’ll fill in some of the details.

Walkway Over the Hudson began service as a railroad bridge spanning between Poughkeepsie and Lloyd in New York, crossing the Hudson River to connect with the larger rail network. Originally it carried a less romantic name, the Poughkeepsie-Highland Railroad Bridge. It opened to rail traffic in 1889, served as a major corridor for passengers and freight, and closed after a fire in 1974. I’m not sure how a steel and iron truss bridge catches fire. I’ll assume there were wooden elements — perhaps track ties that kept the rails at a proper gauge — and offer the civil engineering historians in the audience an opportunity to ponder likely scenarios. It caught fire. It closed.

The bridge stood as a decaying hulk, a metaphor trapped in a post-industrial world, until a group of citizens reinvented it as a pedestrian park. They formed the nonprofit Walkway Over the Hudson to secure public and private funding for an adequate restoration. The bridge reopened in 2009 as the linear Walkway Over the Hudson State Historic Park, a dizzying 212 feet (65 m) above the Hudson River.

Check a search engine for the longest pedestrian bridges and the Walnut Street Bridge (map) will land near the top of the results. It spans 2,376 feet (724 m) with a deck 100 feet (30 m) above the Tennessee River. That’s quite impressive although it’s nowhere near the magnitude of the Walkway Over the Hudson.

A website with the creative name East Tennessee River Valley Geotourism describes the history:

The Walnut Street Bridge is Tennessee’s oldest non-military highway bridge still in use today, restored and revitalized as a pedestrian bridge and linear park. In only a generation, The Bridge has become the centerpiece, and a vital connector of Chattanooga’s riverfront renaissance… Since 1978, when it was closed to traffic for safety reasons after serving Chattanooga for 87 years, the Walnut Street Bridge sat disabled, deteriorating, dormant, and yet another reminder of the city’s decaying downtown. By the late 1980s, the city had taken steps to demolish the downtrodden bridge, but lacked the funding.

Geotourism. I might have to steal that term.

A private organization, The Parks Foundation stepped-in and saved the structure. The 1890 relic reopened as a pedestrian-only bridge in 1993. The deck was changed from asphalt to wood planking in 2010, and added to the charm. Where would we be without private nonprofit groups and foundations to rescue our historic landmarks?

Bob Kerrey Pedestrian Bridge; Omaha, Nebraska – Council Bluffs, Iowa, USA

Aficionados of the Bob Kerrey Pedestrian Bridge remark that it’s the longest footbridge that spans between two states. One must find superlatives where one can find them, I suppose. Even so it spans 3,000 feet (914 m) across the Missouri River with a deck of 60 feet (18 m), and that’s mighty impressive.

There are two points that intrigue me. First, this is a modern bridge (opened 2008) designed specifically as a footbridge. It is only fifteen feet wide which is sufficient clearance for legs and bicycles. It will never carry motorized vehicles. In that sense it reminds me of the Sundial Bridge although it’s more than four times longer. Second, the builders constructed a marker on the state line so that visitors can show-off when they’re standing in two states at the same time.

There’s a third element and I have mixed feelings about it. The walkway was built with Federal dollars so it’s a shining example of an earmark, or should one prefer a more derogatory term, pork. They named it for the Senator who secured the funding. I’m not pointing a finger at him personally because all politicians regardless of affiliation do the same thing.(1) I’ll simply note that this bridge cost on the order of $20 million footed by taxpayers living primarily outside of Nebraska and Iowa. I’d contrast that with the DIY approach used by nonprofits and foundations mentioned previously. It’s a beautiful structure that probably adds to the ambiance of the waterfront, maybe leading to economic growth and new tax revenues, so maybe it all works out in the end? Maybe.

SkyTrail "Canada’s Longest Pedestrian Bridge" (map) represents another claim on the continuum of Internet glory. It began as a railway trestle, 3,000 feet (914 m) long and 150 feet (46 m) above the South Saskatchewan River. The first Canadian Pacific Railway trains rumbled over in 1912 and continued to use it until 1987. It was converted to pedestrian use in 2003 and forms a part of the Trans-Canada Trail.

I like the name of the town, Outlook. The Encyclopedia of Saskatchewan explains, "the railway named the location Outlook for its spectacular vantage over the river valley." I need to walk that bridge someday.

Hornibrook Bridge (R.I.P.), Brisbane, Queensland, Australia

I’m not even going to comment on the unusual name of the bridge. It reminds me of the old joke about the similarity between cheap beer and a canoe.

Once it was considered the longest pedestrian bridge in the world, longer even than the Walkway Over the Hudson. While it existed, it spanned 8,806 feet (1.67 miles, 2.684 kilometres) across Bramble Bay, a solid couple thousand feet longer than the current claimant. Hornibrook Bridge was razed recently so that’s all moot now. It had been a popular attraction for fitness and fishing from its 1979 closure to automotive traffic to its demolition. Alas, no more.

Pedestrians were offered a convenient alternative and it always lacked a certain dramatic visual impact anyway, so that may have lessened the blow. The Houghton Highway runs immediately to the east and a second bridge was added to the highway in 2010. It included a protected pedestrian lane separated from vehicular traffic by a concrete barrier.

Google Street View coverage features an interesting period during the timeline, January 2010 (view). Catch it while it lasts, it’s destined to be overwritten someday. Currently, as of the publication of this article, it shows Hornibrook prior to its demolition plus the new Houghton Highway lanes (the Ted Smout Memorial Bridge) under construction and nearly completed. It’s easy to see why Brisbane added the new bridge — Street View shows two-way traffic on a three lane bridge, without any lane barriers to separate traffic coming at opposite directions and only an overhead crossbar with green and red lights to prevent head-on collisions.

Smout is amazingly close to Smoot. It must be a bridge thing.

Georgia Border Dispute

Several news outlets have highlighted a resolution proposed by Rep. Harry Geisinger of the Georgia General Assembly’s House of Representatives that would seek to move the Georgia border 1.1 miles further north. This has received coverage on both sides of the border from reputable publications such at the Atlanta Journal-Constitution (“Border war with Tennessee gets serious“) and the Chattanooga Times Free Press (“Tennesseans won’t volunteer for Georgia citizenship“). Serious issues and repercussions lay beneath the surface even though many observers dismiss this situation somewhat humorously with a smile and a smirk.

View Larger Map
Much of Georgia experienced a drought of historic proportions through much of 2007. Major reservoirs such as Lanier and Allatoona began to empty, imperiling the water needs of a parched Atlanta. Extreme to exceptional drought with little relief is now expected through the Summer of 2008. By nudging it border north just a tiny bit further, Georgia would be able to tap into the tremendous volume of the Tennessee River at an artificial lake, the Nickajack Reservoir.

Georgia House Resolution 1206 laid out a case that the border is supposed to run along the 35th parallel but was marked incorrectly by a flawed 1818 survey that relied on the imprecise technology available at the time. Georgia further claimed that attempts have been made over the years to rectify the situation but that it has never been adequately resolved. It then calls for boundary commissions to work towards establishing an accurate border both with Tennessee and North Carolina.

In addition to water access, this border adjustment would result in the creation of 40,000 new Georgia residents, with 30,000 coming from Tennessee. More than $2 billion worth of land and property would be carved from Hamilton County, Tennessee alone, including entire Chattanooga suburbs. Logically, Tennessee is opposed to the resolution and has responded rather forcefully in a resolution of their own. They are relying on the doctrine of “adverse possession.” Basically the border has existed this way so long that it’s become the true border in spite of the 35th parallel. Many Tennesseans consider this an assault on their sovereignty for the sake of what they considered irresponsible, uncontrolled sprawl and growth in Atlanta.

There are greater implications beyond Georgia and Tennessee. As populations continue to grow and as competition for resources increase, the battle over water rights long characteristic of the American West have begun to march to the East.
