We take many things for granted in our daily lives here along the rivers and bays where the Columbia River meets the vast Pacific.

None more so than the practical magic of the bridge.


A long, long time ago, a man or woman following a hunting trail came across a stream flooded after a spring snowmelt. Crossing the stream would mean getting wet and it was already chilly and night falling soon. They shuddered at the thought of the wet, of struggling against the currents that might dash them against the rocks, or wash away their spare and valuable handmade tools. They spied a tree that had fallen across the stream — the root-wad on the near bank, the crown of the tree disappearing into the forest on the other side.

In between, the trunk of the mighty tree connected one side to the other — high and dry above the raging waters. They saw a way to make their path safer and better.

The bridge was born.

In time, the natural bridges like this would be replaced by humans creating their own — crude tools felling a tree or dragging a log and piling rocks to make a crossing when no natural bridge was available. It is unlikely that the bridge was man’s first invention, but it may have been the first that involved creating something so long lasting, practical and significant.

There is a bridge still standing that dates to 860 BC that was crossed by the likes of Homer and St. Paul, that still carried the daily vehicle traffic of commerce and civilization until it was closed to cars and trucks in 2006. You can walk or ride your bicycle across it today.

Trial and error, math and geometry — from the strong back of the perfect arch to the sinews of steel cable — bridge design advances on the cutting edge of our practical knowledge while proven designs endure. The Astoria Bridge is the longest continuous through truss bridge in North America. Yet its riveted steel girder triangles look little different from bridges generations older.

The invention that connected the world

It is the invention that first tied the world together.

Bridges fascinate me not so much in their structure, but in the human cooperation necessary for their genesis. In the ancient world, bridges were built for commerce — like the stone caravan bridge in Turkey — as well as to conquer: Roman legions marched with engineers that erected bridges as they advanced across the Western world. A ferry or a ford is a bottleneck for cultural interaction — a limitation on human travel that perpetuates isolation. A bridge allows a free flow of movement that can melt this isolation.

You don’t need to venture to the ancient world to see an example of this. Think about the dozen bridges that cross the lower Columbia River connecting Washington and Oregon. These two states have had very different cultures since their inception, different ideas of taxes and tolls and cooperative planning — not to mention competing economies.

That these two states were able time and time again to bridge the river between them speaks to how an overarching practical necessity for connection can build a cathedral to cooperation.

That is how I see bridges, after all.

Lifetimes of toil to construct

The striking thing about cathedrals is how they spanned generations in their making — that the craftsman who laid the first stone, or the architect that designed it never lived to see its completion. Aside from their religious significance, they are monuments to intergenerational cooperation.

While bridges take far less time to construct, they rarely appear overnight. The Astoria Bridge took more than 40 years from conception to ribbon cutting. The Brooklyn Bridge was designed by John Roebling but chief engineering duties were passed on to his son, Washington, after he was felled by tetanus. Washington was incapacitated by injuries suffered during construction, so Washington’s wife — Emily Roebling — became chief engineer serving both as on-site project manager and political liason to see the massive project through.

First conceived in 1800 — it was not completed until 1883 because the East river’s busy ship traffic required a span high enough to allow a constant stream of world commerce to pass under it. So too does our four mile long span of the Astoria Bridge arch its back 197 feet off the water to allow the endless movement of world trade to glide under its girders. Imagine the problem given to its engineers — design this bridge to be high enough that ships can pass under it — not just sailing ships of yesterday or the modern cargo ships of 1964 — but all the ships of the future as well.

I have talked with people who remember what it was like before these bridges we take for granted, who remember the wooden truss bridges, the swing bridges and draw bridges that would daily bring travel to a halt to allow water traffic to pass. I have talked with those who remember when the ferries were replaced by the Astoria Bridge and I myself have seen the way the removal of the toll across that bridge changed patterns of commerce and commuting in the region.

Crossing and considering bridges

I love to run the Columbia Crossing each year — to take my time to appreciate the marvel of the Astoria Bridge. So too do I love the Grays River Covered Bridge dinner — an annual 4H fundraiser that transforms the last covered bridge over a public road in Washington into a rustic celebration of local talent and bounty.

I love stopping at the top of the nameless practical bridges on my daily runs or motorcycle rides around the valley.

I get a thrill on a hiking trail when some wood structure deep in the forest carries me across the creek. I study it and wonder at the work that must have gone into transporting its materials miles into the woods — assembled just to await the passage of my hiking boots.

It is hard to build a bridge single handed.

I know first hand. A few years ago, I worked to build a sturdy bridge across the seasonal creek behind my house — something strong enough to ride a horse across. Even though the creek I needed to cross was only five feet deep and eight feet wide, it was hard to work the heavy railroad ties into place. Hard to make it solid and level while jumping from one side to the other. Building such a simple span over such a shallow creek gave me renewed respect for bridges I cross everyday — that make my life here possible.

By necessity, then, bridges are monuments to human cooperation and belief in future and practical investing in progress.

Those are things worth celebrating, worth wondering at and worth appreciating the next time you cross a bridge.
