Small Timeline 

1929

February: Legislature authorizes a Tacoma Narrows Bridge.

1938

Nov. 26: Construction begins on the bridge.

1940

May: Two months before completion, workers notice a bounce or "galloping" of the bridge in winds as light as 4 mph. Some chew on lemons to combat nausea.

June: Carpenter Fred Wilde dies of a head injury after falling 12 feet. Days later, a bridge worker falls 190 feet into the water and survives.

July 1: Opening ceremony. Engineers proclaim no danger in the $6.6 million bridge's "bounce." Tolls: 55 cents one-way for car and driver, 10 cents per passenger.

Nov. 7: Just 4 months old, "Galloping Gertie" collapses. In gusts of 42 mph, the roadway at 10 a.m. begins a lateral twisting motion. An hour later, a 600-foot section of road in the western half of the center span breaks free and falls into the water. Minutes later, the rest of the central span falls.

1943

June: The bridge's tear-down and salvage operation is complete. Steel is reused to help relieve shortages during World War II.

I remember reading something to that effect as well Nathan. Although the towers appeared to be unaffected in the old photos, upon inspection they were found to be compromised.

I would have to read the histories again to confirm my memory, but as I recall the specific reasons the towers were scrapped, were that although they did not collapse, they sustained damage as the cables and deck were torn apart and fell into the river. Imagine all the weight of the deck and girders, plus the tension of the cables as that all ripped apart and fell into the river.

I'm kind of surprised that they scraped the towers and cables. I always assumed that the towers, at least were reused.

A small correction. At the time Gertie stood, Washington State Route 16 was then known as Primary State Highway 14A. WA16 didn't become signed as such until Washington reassigned state highway numbers in a renumbering program that took effect in 1964.

It should be changed in the record for historical accuracy, that it crossed the Narrows at Primary State Highway 14A.

Gallopin' Gertie looked pretty nice on opening day!
