spillway from the Missouri Bridge.
is rapidly nearing completion. The
3 spillway contractors are COOPER
ating on this construction. The
new road will reduce the distance
from the east truck ramp of tho
Missouri River Bridge to the spill
way to about ~ miles and will
eliminate excessive GRADES. An
elevatine grader drawn by a trac-
tor, q road grader with tractor,
2 draeline excavators with fleets of
small dump trucks, and 8 bull
dozers have been used on the
construction.
Since the completion of the pilot
tunnels by the Mason . Walsh Co...
the principal work under way from
the upstream portals is that of ex-
cavation for the Concrete foundations
of the control gate shafts. For
these foundations. stopping and
drifting operations are in progress
preparatory to the setting of tenn
porary steel bracine.
The crews of the Mason & Walsh
Co. on the shaft excavations are
becoming adept at their work and
are making excellent progress.
The 2 main shafts have been ex-
cavated IS feet below the surface
OF the ground, while the Z emereen-
cy shafts have reaceed a depth of
~ feet. During the week. 5000
cubic yards of shale were excavated
at these points. This indicates
GOOD progress iDasmuch as every
shovel full of material must first
be loosened with pneumatic pave
ment-breakers. The muck is not
hoisted to the top of the ground.
but is pushed by small bull.dozers
into glory holes" (the pilot shafts
which were previously excavated
in the centers). Todate. over 81, 900
Gu. yds. OF shale have been handled
in the shafts. Duriak tie past week
l57.60z lbs. Of structural steel and
liners have been placed in the
shafts makips . total OF. 71o.2o0
lbs. placed to date. Over 10000
Of cement have been used for
groutine behind the linar plates.
A considerable amount Of work
was accomplished during the week
at the outlet portals. The top six
foot sections Of 7 blocks of the head
walls and the mid-section of one

poured. The concrete floor. or
channel lining. was extended 80

slabs, $500 cu.yds. of concrete we're
'equircd. The excavation has been
made for so additional slabs.
