 Another beautiful Austrian railway bridge in a picture perfect alpine setting, the Trisanna bridge (88 meters high) has a 394 foot (120 mtr) main span that has been reconstructed several times since the bridge first opened in 1884.  The original span was a truss-arch that was first strengthened in 1908 to handle heavier trains.  In 1922 the span was converted into a lenticular truss from the addition of an under slung truss chord below the deck.  For over 40 years the oval lenticular truss gave the bridge a signature look that made it a symbol of the eastern Arlberg rail line.  That finally changed in 1964 when a more conventional tied arch replaced the lenticular truss in a maneuver that only interrupted rail traffic for 10 hours.  The bridge is located just south of Pians, Austria.
-Constructed in 1964, the Jauntal bridge (87 meters high) was the last tall European railway bridge to be constructed before the high speed rail craze began in the 1980s.  The bridge has become the site of a popular bungee jumping operation.  You can find out more here: http://www.bungy.at/de/index_bungee.php

Both bridges cross deep valleys in the Thuringian Forest region. The main span is 513 feet (156.5 mtrs) and supports a thin deck consisting of a trapezoidal steel trough and a simply reinforced concrete slab. On a cost per mile basis, the A71 is the most expensive highway ever built in Germany. The Rennsteig tunnel is also on the A71. At 5 miles (8 kms) in length, it is the longest road tunnel in Germany.

+The late 1960s viaduct known as Tiefenbachtalbrücke (92 meters high) crosses a creek several kilometers north of Stromberg in the Rhineland-Palatinate region of Germany  with 7 steel girder spans of 172 feet (52.5 mtrs).
 The Lösterbachtalbrücke (90 meters high) was one of Germany’s highest Autobahn bridges when it opened in 1974.  Located near Nonnweiler, Germany, the 4-lane structure is reported by some sources to be over 100 meters high.  The wide, single 4-lane deck is largely supported by struts that connect to the main box beam core.

 Located on the A15 autostrada 8 miles (13 kms) north of Pontremoli, the Roccaprebalza Viaduct (90 meters high) was the highest double decker road bridge in the world upon its completion in 1975.  While hardly an attractive structure, it was still sad to see its replacement in 2008 by two separate viaducts for north-south traffic.  The highest double decker bridge in the world is still the Pit River bridge in the U.S. state of California which carries a highway and railway over Lake Shasta.

−	The New Park (10 Mile) bridge (98 meters high) was the largest component of a complete realignment and upgrading of the Trans Canadian Highway Route 1 through Kicking Horse Canyon in British Columbia. Steep gradients and tight turns were a constant problem along the original 2-lane highway in the vicinity of the original Park bridge deck truss. By creating a 4-lane divided highway and raising the elevation of the crossing, accidents and travel times were reduced. The nearby Yoho (5 mile) bridge was also completely rebuilt due to a dangerous “S” configuration on the alignment of the outdated 1959 structure.

−	At 295 feet (90 mtrs), Park Bridge’s pier number 4 is the tallest ever built in Canada. The right of way of the famous Canadian Pacific Railway runs along the Kicking Horse river 289 feet (88 mtrs) beneath the bridge. The Park bridge is located 8 miles (13 kms) east of Golden, British Columbia.

	The largest conventional trestle railroad bridge ever built, the mile long Lethbridge Viaduct (94 meters high) opened in 1909 across the Oldman river in the southern Alberta province city of Lethbridge. The crowning achievement of the Canadian Pacific railway, the bridge was actually a bypass to the original route that went south across the St. Mary’s river and over numerous coulees on a series of timber Howe truss trestles that were not built to last more than 10 or 15 years and required constant maintenance. A new direct crossing over the Oldman river shaved 5 miles (8.5 kms) off the original route.

	The A81 was one of Germany’s earliest high bridge autobahns. The Jagsttalbrücke (80 meters high) near Widdern is a perfect example. The simple piers support a 98 foot (30 mtr) wide deck cantilevered out on struts supported by a 17 foot (5.25 mtr) deep steel box beam. The bridge was completed in 1974.

 Beset by major construction delays relating to the construction of the main span, the final bridge will consist of twin box beam concrete arches 689 feet (210 mtrs) long, each supporting 3 lanes of traffic along I-580 south of Reno, Nevada.  Construction on Galena Creek initially started back in 2005 on the approach span piers with Edward Kraemer and Sons Inc. as the contractor.  Work was then halted in 2006 over a contract dispute with the Nevada Department of Transportation.  The contractor was worried that the main arch span could collapse during construction from high winds.  The two sides disagreed and decided to part ways.  It was not until 2007 that a new contractor - C.C. Myers of California - was brought in to take over.

 The solution was simple enough.  Instead of constructing the arch outward over the canyon in segments by the stayed cantilever method or by constructing wind prone falsework 300 feet (91 mtrs) high, the Galena creek valley would be filled halfway up, creating a giant rock embankment where a much lower and more solid falsework 150 feet (46 mtrs) high could be built on flat ground from one end of the arch to the other.  Once the bridge is completed, the embankment will be completely removed right down to the original creek bed, 300 feet (91 mtrs) below the road deck.

 The highest railway bridge on the famous Chihuahua al Pacifico railway in Copper canyon, the Puente Chinipas bridge (90 meters high) was completed in 1961.  Two bulky concrete piers support a 3-span truss with a maximum span of 295 feet (90 mtrs).  A number of years later, the lower half of the bridge was submerged in a reservoir.  The Copper Canyon line has several other tall bridges in the 50 to 60 meter height range including Cascada, La Laja and Fuerte.

 North America’s highest suspension footbridge, the puente Ojuela or Mapimi (90 meters high?) near Torreon in the state of Durango was originally built in 1898 to carry a mining car rail line.  The tracks were eventually pulled up and the gold mine was abandoned.  The structure was refurbished in 1992.  The main span of 1,030 feet (314 mtrs) is longer than any other pedestrian bridge in North America.  The height may be as low as 65 meters.
