Near This Location In The 1930's James E. Love And Horace D. Hume Of Garfield, Washington, Invented The Flexible Floating Cutterbar And The Tined Pickup Reel To Harvest Low-Growing, Fragile Crops. These Devices Were Developed For The Local Crops Of Dry Peas And Lentils And Were Then Adopted Nationwide To Soybeans And Other Low-Growing Crops That Tangle And Lodge. These Mechanisms Reduced Dry Pea Harvesting Costs By 28% And Crop Loss From 50 To 10%. These Inventions Were Reported To Save The Equivalent Of 2,750,000 Acres Of Soybeans Annually.
The Purdue University Airport was the first collegiate owned airport in the United States. It hosted Amelia Earhart for her final adventure, was the training ground for test pilots such a Jimmy Johnson and Ivan Kincheloe, balloonist Malcolm Ross, and astronaut Neil Armstrong. Purdue University Airport and its people and programs pushed aviation’s evolution to new heights and helped expand the frontiers of flight. During WWII, hundreds of U.S. Army and Navy members were trained at the airport.
With the dawn of the automobile age at the beginning of the Twentieth Century, the entire nation started to demand better roads. In the 1910s, motorists and businessmen in Utah became aware of the possibilities of tourism as a business. Soon the state of Utah and the federal government responded with a decades-long program to improve transportation to and within Zion National Park.
Several factors argued for a road through Zion National Park:
When this 1,850-foot concrete-arch highway bridge was built on the White River in a remote region of northern Arkansas - prior to the construction of upriver, flood-control dams - flash floods occurred frequently, sometimes causing the water to rise as much as one foot per hour. Construction under these conditions presented a clear danger, so project managers specified both a design and an innovative construction method appropriate to the problem of building across a perilous stretch of unpredictable river.
The Salginatobel Bridge, spanning the Salgina Valley ravine, is the earliest surviving three-hinged, hollow box arch bridge designed by Robert Maillart.
The Detroit-Windsor Tunnel is a 5,160-foot structure that carries traffic under the Detroit River between Detroit, Michigan and Ontario, Canada. Privately financed, built, and owned, it was completed in 26 months, 10 months ahead of schedule.
The total length of the Columbia-Wrightsville Bridge is 7,374 feet. Its construction required 100,000 cubic yards of concrete and 8 million pounds of steel reinforcing rods.
