I love bridges! I've always been interested in them. Maybe it started back when I was seven years old and heard about the moving of the London Bridge to Arizona, piece by piece...how cool is that! Or my fascination whenever I go over a really high bridge and see the great view from it. Or seeing some new innovation in bridge design or a good-looking bridge, be it in the daylight or at night. If you haven't already done so, please read through "THE SERIES EXPLAINED" section below and then work on this fun, informative, and easy puzzle.

THE PUZZLE
This is the fourth in a series of caches about bridges. This set is about interesting bridge designs.
The final coordinates for this puzzle are determined by finding the following answers.
Coordinates are: N43 AB.CDE W77 FG.HIJ.
A: Øresund Bridge (Danish) or Öresund Bridge (Swedish)
Across the Øresund strait between Sweden and Denmark
Longest combined road and rail bridge in Europe. It connects two major metropolitan areas: Copenhagen, the Danish capital city, and the Swedish city of Malmö, connecting the road and rail networks of the Scandinavian Peninsula with those of Central and Western Europe. A data cable also makes the bridge the backbone of Internet data transmission between central Europe and Sweden.
There are three pieces to the crossing:
- The bridge that runs nearly 8 kilometres (5 miles) from the Swedish coast to Peberholm.
- The artificial island of Peberholm.
- The 4-kilometre (2.5 mi) Drogden Tunnel from Peberholm to the Danish island of Amager.
Be sure to look through the wikipedia page and read about these three pieces.
A is the second digit in the height of the bridge, in meters.

B: Evergreen Point Floating Bridge
Seattle, Washington, USA
The Evergreen Point Floating Bridge carries Washington State Route 520 across Lake Washington from Seattle to its eastern suburbs. The 7,710-foot-long (2,350 m) floating span is the longest floating bridge in the world, as well as the world's widest measuring 116 feet (35 m) at its midpoint. The bridge opened in April 2016 and replaced another floating bridge of the same name at the site, which was 130 feet (40 m) shorter.
B is the first digit in the number of anchors that secure the bridge to the lake bottom.

C: Puente de la Mujer (aka Women's Bridge)
Buenos Aires, Argentina: A portion of the bridge rotates 90 degrees to allow water traffic to pass.
C is the number of millions in US dollars that the bridge cost.

BONUS VIDEO: See the bridge in operation. Be sure to check out the size of the boat that passes through.

D: Mathematical Bridge
Cambridge, United Kingdom
Although it appears to be an arch, the Mathematical Bridge is composed entirely of straight timbers built to an unusually sophisticated engineering design, hence the name. The arrangement of timbers is a series of tangents that describe the arc of the bridge, with radial members to tie the tangents together and triangulate the structure, making it rigid and self-supporting.
D is the third digit in the year of the second rebuild.

E: Hörn_Bridge
Kiel, Schleswig-Holstein, Germany
The Hörn Bridge is a three-segment bascule bridge with a main span of 25.5 metres (84 ft) that folds in the shape of the letter "N".
E is the second (or third) digit in the year that the bridge was built.

F: Newport Transporter Bridge
Newport, South East Wales
Also known as a ferry bridge or aerial transfer bridge. A suspended gondola carries motor vehicles (including buses and multi-sized trucks), cyclists and pedestrians across the river. For this location, the design was chosen because the river banks are very low at the desired crossing point where an ordinary bridge would need a very long approach ramp to attain sufficient height to allow ships to pass under, and a ferry could not be used during low tide at the site.
F is the first digit in the total length, in meters, of the bridge.

BONUS VIDEO: See the bridge in action.

G: Humpback Covered Bridge
Alleghany County, Virginia, USA
The Humpback Covered Bridge is one of the few remaining covered bridges in the United States that was built higher in the middle than on either end; hence the name of "humpback". The supports incorporate a unique curved multiple kingpost-truss system that is not found in any other surviving wooden bridge in the U.S.
G is the third digit in the year the bridge was built.

H: Haarlem Submerged Bike Bridge
Haarlem, Netherlands
Innovative idea to solve a need for an unobstructed bicycle path. See article and its video for details.
H is the first digit of the height, in centimeters, of the waterproof steel "box" the cycle path was built in.

I: Kawazu Nanadaru Loop Bridge
Kawazu, Japan
Solution for getting vehicles up a mountainside when a straight road won't work. This bridge takes traffic through a change in height of 147 feet.
I is the first digit in the number of degrees that vehicles rotate through.

J: 3D-Printed Bridge
Gemert, Netherlands
While there have been other 3D printed bridges created before this one, this is the first one printed using reinforced concrete. It involved printing about 800 layers of the concrete material, which was both reinforced and pre-stressed.
J is the second digit of the span, in feet, of this bridge.

THE SERIES EXPLAINED
To share my interest in bridges I've created this series of 12 caches. For each cache you'll look up information for 10 bridges. The bridges are from around the world, and no bridges are repeated throughout the series. So 12 caches with 10 bridges...120 bridges for you to enjoy!
The caches will be released throughout the winter months, allowing you to spend some time sitting nice and cozy in your pajamas & bunny slippers, researching the answers and watching videos or viewing photographs about each bridge. And I even give you links to where you can find the answers! Once you've solved it though you'll need to take off the bunny slippers, bundle up and go find the cache.
I've tried to make the hides as winter accessible as possible for the location. Happy caching!
