Hoover Dam Bypass Project
– Boulder City, Nevada – In the spring of 2005 we
were awarded a subcontract by Obayashi Corporation (Project General
Contractor) to participate in the construction of one of the largest
arch bridges in the world. The Hoover Dam Bypass Bridge has been
in the works ever since the tragic day of Sept 11, 2001. Since
that fateful day, interstate traffic has been greatly restricted
for crossing the Hoover Dam. All semi trucks and other large vehicles
have been rerouted to other highways around the dam for security
reasons. The rerouting has added hours of extra travel time for
these drivers, so the need for the Hoover Dam Bypass Bridge was
very apparent. The Hoover Dam
Bypass Bridge will be the 4th largest concrete arch bridge in
the world. It will span the canyon just below the Hoover Dam.
Our part of this $130 million project will be to erect the 350’
tall twin cable ways that will carry the bridge material across
the canyon. In addition to the cableway erection, we will erect
all the vertical precast concrete columns, horizontal steel tub
girders, and we will install the stay in place metal decking.
This project is scheduled to be complete by late 2007 or early
2008.

Arch Bridge - Hurricane, Utah - During the
first quarter of 2003, OLSENBEAL erected a 300' wide 40' tall
arch spanning the Virgin River Gorge between Hurricane and LaVerkin,
Utah. The Gorge is over 120' foot tall.
We erected from the south abutment with our MAXER attachment and
from the river floor as well. We used 50 ton temporary holdback
towers during erection to hold the individual arch pieces out
until the middle. We are currently finishing the post deck work
and will begin the rehabilitation of the existing arch structure.

OLSENBEAL finished with the Utah I-15 Reconstruction Project
in April of 2001. In 1997, we combined with four steel fabricators
and one detailing firm to form the I-15 Steel Structures, LLC.
Over the next four years, we erected 65,000-tons of steel and
over 175,000 lineal feet of pre-cast girders for a combined total
of 154 bridges. Being the sole erector for this project was a
daunting responsibility, but OLSENBEAL was up to the challenge.
We finished the erection of all bridges on time or, in most cases,
ahead of schedule. We met and exceeded expectations in our role
for completing this major highway expansion. OLSENBEAL received
the NSBA steel bridges special project award for our part
in the I-15 reconstruction project.
Special Project Category Winner!
• In June of 2001, OLSENBEAL completed another challenging
project - the construction of a steel plate girder bridge that
spanned across the CC&V gold
mine canyon - located in Victor, Colorado. One major obstacle
on this project was crane access. Due to the steep sloping, rocky
sides of the canyon, we were limited in the locations for our
crane pads. Canyon winds and weather conditions also made this
project a challenge, but we were able to erect it on time and
remain within budget. This bridge is the tallest steel plate girder
bridge in Colorado. At its tallest point, this bridge is elevated
250’ off the ground, it is over 1,200 feet in length, and weighs
approximately 2,436,000 lbs. (Steel).
 OLSENBEAL
has been building Steel and Pre-cast bridges since 1987. Since
our beginnings as a company, OLSENBEAL has always looked for the
fastest, safest, and best way to erect bridges. In 1989, we erected
the Eagle Canyon arch bridge in Southern Utah. This
arch bridge challenged our erecting crew, as we did not have access
to the canyon floor. We came up with a suspended holdback tower
system as a remedy.
