T
he iconic Siuslaw River
Bridge has reigned over
Florence since its completion
in 1936. Now, Oregon Department of
Transportation (ODOT) is overseeing
improvements to increase the integri-
ty and longevity of the bridge. The
main components of the Cathodic
Protection Project, scheduled to be
completed in March 2019, are repair-
ing damaged concrete and replacing
bridge railings. Additional features
include seismic improvements and
safer and more accessible sidewalks.
The Siuslaw River Bridge is one
of five major bridges constructed
along the Oregon Coast Highway
(Highway 101) during Franklin D.
Roosevelt’s presidency. Engineer
Conde B. McCullough created a
unique Art Deco design for each of
the bridges, emphasizing symmetri-
cal patterns, geometric forms, elegant
arches and sunburst motifs.
“I just love our bridge,” said
ODOT Public Information Officer
Angela Beers Seydel. “It’s beautiful.
I was so sad when they took down
the Alsea Bay Bridge. That’s why
we’re doing this. We can’t lose
another one.”
Due to corrosion, ODOT demol-
ished the original Alsea Bay Bridge
in Waldport in 1991 and replaced it
with a more modern, durable span.
“There’s pain in keeping the
bridge updated, but it’s something to
keep investing in. There’s a reason
these bridges are iconic,” Beers
Seydel said.
ODOT awarded Hamilton
Construction Co. the primary bid for
the Siuslaw River Bridge project.
The secondary contractor is Great
Western, who specializes in the zinc
application process of cathodic pro-
tection. The process involves sand-
blasting and cleaning concrete before
coating surfaces with zinc.
According to ODOT, installing a
zinc surface coating on coastal
bridges protects the reinforcing steel

tiny birds, weighing little more than a
penny, have made an impressive jour-
ney of more than 3,500 miles from
wintering sites in Mexico.
The name “rufous” refers to their
rust-colored feathers which, in males,
are especially vivid and accompanied
by a fiery orange throat.
Arriving in our yards, these little
gems join the larger, green Anna’s
hummingbird, which overwinters in

“That’s the delight about the coast,
however. You have a rainy day and
turn around and it will be sunny.”
During April, crews will be work-

will begin to move north.
Beers Seydel said people driving
on Highway 101 should expect some
lane closures during the day for
bridge rail replacement and other
work. Delays may be up to 20 min-
utes, but will normally be five min-
utes or less.
When ODOT began the bid
process in 2014, a letter sent out to
the community said, “Overall, the
bridge preservation project is both
for historic preservation and safety.”

Gems of springtime
al and often described by field guides
as pugnacious and feisty.
They may even chase larger hum-
mingbirds away from feeders, but who
can blame them? We’re all a little
grumpy after a long-haul journey and
they’ve done it powered only by flower
nectar.
In addition to being accomplished
travelers, rufous hummingbirds are
notable for their memory and learning
abilities associated with locating food
sources. As they zoom around our
yards, they may appear to be randomly
flitting between flowers or feeders, but
the birds are actually making decisions
on where to find nectar.
For instance, they can remember
which flowers have been emptied and
avoid visiting them until the nectar has
had time to replenish. Such efficiency
in feeding is important for sustaining an
animal whose resting heartrate can be
around 500 beats per minute.
While we often associate humming-
birds with red flowers, and most back-
yard feeders are red, biologists have
shown that the birds rely more on
flower location rather than color when
choosing where to feed.
Experiments using artificial flowers
show that rufous hummingbirds return
to a location where they were previous-
ly successful in finding nectar even if
the color of flower in that location has
changed.
This location-based memory appears
to be based on recognition of nearby
landmarks similar to how you could
still find your favorite coffee shop even
if it had been painted a different color
since your last visit.
We are lucky to host such amazing
birds in our own backyards, and their
brightness is a very welcome sight at
the end of a gray Oregon winter.
So get your feeders out and enjoy
these little springtime gems.
