Astounding Japanese Highways, Bridges & Interchanges
Japan saw most of its infrastructure bombed back to the stone age in
the final years of World War II, which makes the country's post-war
rejuvenation all the more astounding. Huge, complex public works
projects saw a concrete & steel web of highways, bridges and
interchanges blossom from the wreckage of war.
Today, shaped by the demands of restrictive space and economic boom &
bust, Japan's hardened transportation arteries display artistic forms
that go far beyond their functions.
Above left is the Hakozaki Junction, part of the Metropolitan
Expressway in Tokyo, and at right is the Hokko Junction in Osaka...
These images illustrate the solution engineers used when building
multi-lane highway interchanges in some of the world's most crowded
cities in Japan: go vertical!
Ken Ohyama has made it his mission to chronicle some of the more
striking Japanese roadworks in a Flickr series called Interchange and
a book of his photos available from Amazon. One of the more
outstanding examples is The Hokko Junction shown above - a part of the
Hanshin Expressway near Japan's second city, Osak
Also in Osaka is the Higashiosaka (East Osaka) Loop of the Hanshin
Expressway. The photographer's technique gives the sweeping curve of
the roadway an almost tubular appearance
When engineers have space to work with, they take full advantage. This
wide field view of the Higashiosaka interchange shows the almost
organic complexity of a busy cloverleaf, resembling a living
creature's circulatory system with the vehicles acting as blood cells.
Highways upon highways... without any end in sight:
One interesting feature of Japanese elevated highways: they often run
above rivers or sea channels, using the available space above the
water. Here are some of these "highways on the sea"
The incredible Japanese road infrastructure really took off in the
1960s - check out the vintage photo on the right:
Such "Bladerunner" sights are commonplace now, brimming with urban
energy -
By the way, for the tricky "urban density" photography, head over to
this page... and see if you can spot something wrong with the image
there.
Slipping Sideways
Some sections of the Hanshin Expressway suffered severe damage during
the 7.2 magnitude Great Hanshin Earthquake which hit the Kobe, Japan
area in January of 1995, killing over 5,500 people and costing over
$200 billion.
On the bright side, the affected sections of the highway did not
"pancake", as happened in the 1989 Loma Prieta quake, but instead
slipped sideways and tumbled over. Either way, one doesn't want to be
driving through a highway interchange or junction when a big quake hits!
Recession, what recession?
Public works spending has long been the Japanese government's
preferred way to spend budget surpluses, boost employment, keep the
ruling party's supporters in the construction industry loyal, or all
of the above. The highway depicted below is one of those projects,
steadily overtaking a quiet city street like Godzilla in slow motion
Which came first, the highway or the building? The question is moot as
both have learned to accommodate one another. The Hanshin Expressway
takes a shortcut through the 5th to 7th floors of Fukushima's Gate
Tower building, also known as the Bee Hive.
The story goes that the original building's owner wanted to knock it
down and rebuild, but was told by city planners that the space was
being allocated to a newly planned exit of the expressway. Both sides
refused to budge, and the compromise was completed in 1992.
Tokyo residents can easily avoid using the highways and expressways
which crisscross the city, thanks to one of the world's largest and
most efficient subway systems, but when traffic is light they can be a
pleasure to drive. The view can be pretty intense, as in the time-
lapse photo below
Urban density in Tokyo is simply astounding
The Rainbow Bridge and the longest suspension bridge
Dark Roasted Blend has been covering some rather fascinating bridges
before. Here are a few more - a spectacular sample from Japan. The 570
meter (1,870 ft) long Rainbow Bridge spans the northern (inner) part
of Tokyo Bay and has been a city landmark since it opened in 1993. Two
roadways, a transit line and pedestrian walkways all use the bridge,
resulting in a seemingly chaotic tangle from certain angles.
It's at night, however, that the Rainbow Bridge comes alive with
signature color! Spotlights mounted at strategic locations bathe the
bridge's superstructure in prismatic glory. Best of all, the lighting
is solar powered with energy stored during the day powering the light
show at night
Announced in 1969, the massive Kobe-Naruto highway route project
stretches 81 kilometers to connect Japan's main island of Honshu with
the much smaller island of Shikoku to the south. The jewel in the
crown is the 4-kilometer long Akashi Kaikyo Bridge, which cost $3.6
billion to build over the ten year period between 1988 and 1998
Of course, any discussion of Japanese highways wouldn't be complete
without mention of Mount Fuji. The mountain's iconic snowy peak is
visible from Tokyo - on clear days, at least - but though it's
certainly possible to reach the dormant volcano's doorstep via
highway, taking the Shinkansen bullet train is a better bet
ooroo
Bad typists of the word, untie.
