USACE Tillamook Bay Oregon

Tillamook has a more interesting history than most towns of its size and obscurity.

While most towns north or south of it on the Oregon coast have catered to the vacationer, with beachfront motels and seafood restaurants, Tillamook remains a working town.

And although it is situated along U.S. 101, which is the famous Coast Highway, Tillamook is back from the ocean, in a wide flat valley filled with cows and lumber.

There are also a series of prominent mud flats.

But the predominant impression is of green: vast pastures filled with cows. Tillamook is primarily a dairy town, with several cheese factories.

There is a short-line railroad with a diesel locomotive painted in the black-and-white patchwork of a Holstein cow. Tillamook Cheese Factory

Self-guided tours of the Tillamook Cheese factory are available, with samples of curd and Cheddar. The factory produces 40 million pounds of cheese each year. You can watch it being made in 40-pound cubes and then cut by automated cheese slicers into smaller familiar sizes. An small army of snood-headed women watches over the assembly line to keep track of errant chunks of cheese and misshapen cubes.

I briefly considered buying a whole 40-pound block but changed my mind when I discovered it would cost about $120.

The high school football team is known as “The Fighting Cheesemakers.”

Tillamook was also the site of the worst natural disaster in Oregon history, in 1933 with the first of a series of devastating forest fires known as the ”Tillamook Burn.”

The fire had a 15-mile front and in only two days destroyed 255,000 acres. And the fire raged for four weeks.

Fires recurred every six years until 1951, causing them to be named the ”six-year jinx.” Ultimately, 325 square miles were burned. It cost $13 million to reforest the blasted areas, which now look green and woodsy.

Natural devastation also did in the vast land speculation known as Bayocean. Beginning in 1906, a series of investors cooked up a scheme to turn a sand spit at the mouth of Tillamook Bay into a vacation paradise, with cottages, hotels and a gigantic natatorium with heated water.

Lots were sold, buildings were built and sales were slow, in part because there was no way to get to the development. There were neither roads nor trains, and the yacht that was supposed to carry passengers across the bay was too large to pass over the mud bars.

But more devastating was the fact that the builders hadn’t taken into account the nature of spits: They grow and shrink with the waves, and it wasn’t long before Bayocean’s cottages fell into the aggressive surf. There was a brief period of prosperity in the community during the ’20s, but by 1932 the natatorium collapsed into the sea. In 1952, a storm split the spit into three smaller islands. The last vestiges of construction on the spit were wiped out in 1960. Today, it is just a story they tell in town.

I doubt many in Tillamook still sing the popular song from 1925, Tillie From Tillamook: ”Tillamook Tillie got wild one day, packed up her things and went away. She got weary of the birds and the bees and living on Tillamook cheese.”

According to the song, she moved to Manhattan and the chorus sings out: ”Wooden shoes, a hole in her sock, knees that knock-knock, knock-knock. She’s lopsided and she got that way getting up at break of day. Tillie, Tillie, Tillie, sweeter than the new mown hay. She’s the crash of Broadway today!”

Another piece of Tillamookana, however, is still there to see, just south of town: the world’s largest wooden building. It is a blimp hangar built during World War II for the Navy. There used to be two of them, but one burned down in 1992 when its contents, $300,000 worth of straw, caught fire. The conflagration was so intense that the fire drew 80 mph winds into the hangar.

The remaining hangar for now contains the Tillamook Air Museum, with a handful of World War II-era planes, a couple of blimps and some helicopters, along with interpretive exhibits that tell the story of the hangars and the blimps that were used during the war to patrol the Pacific looking for Japanese submarines.

The building is 1,080 feet long, 300 feet wide and 195 feet high and covers 7 acres. You can’t miss it as you drive along 101. There are geological features listed on maps that are smaller than this great humpbacked mega quonset hut.

Forget the bridges of Madison County, the bridges worth writing about are on the Oregon coast.

As the coastline meanders in and out along the Pacific, the roadmakers were faced with two problems: how to climb the rocky headlands and how to bridge the broad, flat river estuaries. They took care of the headlands with dynamite and pick, but the rivers were something else.

First, they were unusually broad, combining, as they do, elements of river, estuary and tidal mud flat. The soft ground didn’t make it easy to anchor a bridge. Second, the usual material for building bridges in the early part of this century was iron, which tended to rust out very quickly in the salt-spray air of the coast.

Consequently, most rivers were crossed only by ferry, even after the Pacific Coast Highway was dedicated in 1923. It wasn’t until federal matching funds were made available for highway construction, and later the Works Progress Administration kicked in, that the final T’s were crossed and the last bridges were installed.

Now, bridges ordinarily don’t get me excited. I like a good bridge as much as the next guy, but I can’t claim to be a fanatic. conde mccullough

But the bridges that cross the Oregon coast are different. They are some of the most beautiful bridges ever built. And the credit goes to one exceptional man: Conde McCullough, a South Dakota-born engineer who presided over the Oregon Highway Department as bridge engineer during those critical years.

His designs are admired both for their engineering skill — he was an innovative engineer and used many new techniques, including prestressed concrete, for the first time, or very nearly so — and for their aesthetic grace.

I cannot speak with any authority on their technical aspects, but I can say that, taken as a whole, they are the most beautiful set of highway bridges I’ve ever seen.

McCullough had a few recognizable habits. He used a good deal of Art Deco ornament on the bridges. Many have decorated pylons at the entrance to the bridge. Others have abstract floral scrollwork carved into their girders.

And these certainly make the bridges distinctive.

But it isn’t the ornament that makes them so satisfying to look at; rather it is the incredible sense of proportion and rhythmic movement McCullough managed to enshrine in his steel and concrete sculptures.

Anyone who has taken notice of the mint-green steel arches between molded concrete abutments that cross the river mouths on the Oregon coast will be able to recognize McCullough’s handiwork whenever else he sees it.

The bridge over Coos Bay, for instance, which now is named the McCullough Memorial Bridge, is a series of long arches like the path of a bouncing ball. Over them the roadway passes, rising slightly and connected to the arches underneath with a series of vertical beams, just the same graceful thickness as the arches themselves.

And across the main span, an equally graceful series of steel girders crosses the roadway in a series of gothic arches, crossing themselves in a way reminiscent of the great crossed arches of Exeter Cathedral in England.

As you drive across, you can’t help but have the feeling that you are driving down some great dignified nave.

His bridge over the Rogue River is a counterpoint of tall, Roman-aqueduct-style arches against the longer bouncing-ball arches of the spans themselves. Built in 1931, it was the first structure in America to be constructed with the Freyssinet method of pre-stressing concrete and has been designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers.

Three different types of arch work together in the Cape Creek Bridge at Devil’s Elbow State Park, and in the Yaquina Bay Bridge at Newport, the 3,223-foot structure is a graceful ascending line of highway supported by long, flowing arches, with a center-span arch that leaps high above the roadway. The center span is further set off by the concrete ”finials” that top off the support span.

A lot of money has been spent on public art, but very little is of such lasting significance as these civil projects created by an engineer who was also an artist. When McCullough died in 1946, he left a more lasting and distinct personal signature on the state than any political or social leader.
