The Twin Falls-Jcrome bridge
across the Snake river in Idaho bears
the proud title of the highest bridge
in the world, 476 feet from bridge
floor to surface of the water. It
is 1,400 feet in >ength longer than
the International Bridge at Niagara.
Romance surrounds its location.
The dsep canyon of t‘ e Snake river
formed an almost impossible barrier
to the pioners from the days of
Lewis and Clark to the covered
wagons of the old Oregon Trail. It
threatened the loss to us of the
Oregon country. Many of Dr. Whit- i
man's party went south to Califor
nia, with only a few brave souls
holding to the Oregon Trail throurh
the perils of crossing at this point.
Nation’s Bridges Tell
Story of Progress
The highest, longest and largest
bridges of the world arc in America. ■
and according to economic authori
ties, are necessary and typical of !
American progress. The process of
overcoming natural barriers is un
der way and has been accomplished
by large construction companies.
The most spectacular engineering
feats of the age are such works as
the Twin Falls-Jerome bridge in
Idaho, the “Bridge of the Gods," I
across the Columbia river; the mile
long Camdcn-P’r.iladelphia bridge
with the largest span in the world,
and even the old Brooklyn bridge
in New York City.
Others are being planned, such as
the proposed span across the Golden
Gate in San Francisco, and one pro
* je^ Led to connect New York and
New Jersey across the Hudson river
at 179th street, Fach of these, it
is estimated, will have a span twice
the length of any span exising to
Longest Swing Span
The Chehalis river bridge at Aber
deen has a swing span of 303 feet,
the greatest in Washington. This
great reach swings on a central pivot
in the middle of the stream. It was
designed by M. M. Caldwell, bridge
engineer of Seattle, who also de
signed the Gateway bridge.
The Wishkah river bridge in Aber
deen, Wash., differs from the swing
span type of bridge in that it is of
'‘jack-knife’’ construction or Straus
Bascule type. The mam span lifts

Steel Men Encounter
On Gigantic Projects
Samuel H. Hedges, an engineer
who has served the Northwest in
many of its greatest projects, was
asked about the effect of the safety
movement on steel workers. He re
plied, “It has given the men as much
pride in doitg a job without acci

“Lives actually lost in the ‘steel

In Span's Design
The Pasco-Kennewick bridge,
crossing the Columbia river at Pasco,
Wash., was one oi the first toll
bridges in that part of the country.
It took the place of the old ferry
plying between Pasco and Kenne
wick. The total length of the struc
ture is approximately 3,000 feet,
with 1,530 feet of steel structure
Its construction was notable in an
other way, from the standpoint of
architectural design. It was in this
bridge that the designer M. M.
Caldwell, of Seattle, introduced what
seemed n radical change, but which
has since been accepted a> a stand
ard of art design in brilj e construc
tion. It was the change from the
; old fashioned piers to piers of
beauty. The Pasco Kennewick bridge
was built with the arch pier, which
most recent books on foundations in
I corporated in their descriptions of
i modern pier design work.
Air Supply In
In Tunnel Project
Unusual extremes were faced in
the building of the Duwamish river,
tunnel for the city of Seattle. Con
stant air pressure waa necessary to:
make it possible for the men to work
on this project, and even then their
lives were in danger at every step '
The extreme difficulty was caused
by having to work tnrough mud,j
with a cover of only anout 17 feet
and 20 feet of water. With this
treacherous cover, air pockets were
dreaded every minute. If the air
had escaped and the water had come
in, lives would have been sacrificed.
Every known precaution was brought
into play, while the strange job
was inched along a little at a time
to its final completion.
An outstanding record was made in
the building of the world’s highest
bridge in Idaho, wher- the only ma
jor accident occurring was a frac
tured elbow! Even this happened
on solid ground, after the most dan
gerous work of building the bridge
itself was completed.
Great Steel Span
Is Still “Bridge of
Gods” Over Columbia
One of the world's longest bridges,
the great steel “Bridge of the Gods'*
ut Cascades, is also one of the most
| romantic and picturesque in the
world. Stretching its 1,570 feet far
across the Columbia in the upper
Columbia river gorge, the grent
span takes the place of the legend
ary natural archway which was trod
by Indian warriors.
A great volcanic lattle between
the two mountain* on each side of
the canyon, Mr. Hood and Mt. Adams,
destroyed the huge natural bridge,
according to the legend, and the

fall of the Willamette Indians.

spot, commanding the same wild, pic
turesque view. It is widened out at

the great scenic vistas of the world.
This famous bridge connects!
Washington and Oregon a: a strate-,
gic point, where scientists admit the
sheer cliffs rising high on both sides
of the river may give some basis
in fact to the romantic legend.
Great mountainous arms reach into
the air on both north and south
banks of the river, forming a set

of the Gods” is of steel construction

Some 2,000 tons of steel were used
[ in its construction.
