This Creative Development Which Was Responsible For The Survival Of The Cotton Industry In The United States Occurred In General Nathaniel Greene's Plantation Near Savannah 10 Miles Northeast Of This Marker. Separation By Hand Labor Of The Lint From The Seed Of The Desired Upland Variety Of Cotton Produced Only One Pound Per Day Per Person. Eli Whitney, A Native Of Massachusetts And Yale Law Graduate, Came To Georgia To Teach School In Late 1792, At Age 27. Mrs. Catherine Greene, Widow Of General Greene, Invited Whitney To Her Plantation, And Urged Him To Design A Cotton Gin.

First Central Station in South Carolina
Society: IEEE Main Category: Electric Sub Category: Era: 1880-1889 DateCreated: 1882 United States Electric Illuminating Company Charleston State: SC Zip: 29401 Country: USA Website: http://www.ieeeghn.org/wiki/index.php/Milestones:First_Central_Station_in_South_Carolina,_1882 Creator: Maxim, Hiram

The United States Electric Illuminating Company of Charleston started up South Carolina's first central station for incandescent lighting in October 1882 -- only one month after Thomas Edison opened his famous Pearl Street plant in New York City. In the following years, the company's parent firm was a major force in the growing electrical industry.

El Camino Real - The Royal Road
Society: ASCE Main Category: Civil Sub Category: Roads & Rails Era: 1000-1599 DateCreated: 1519 Mexico City to Santa Fe State: NM Zip: 87501 Country: USA Website: https://www.asce.org/project/el-camino-real---the-royal-road/ Creator: Spain, Kingdom of

El Camino Real (literally, "the royal road") is the oldest and longest historical trail in the Western Hemisphere. The transportation link has, through the centuries, been called various names, including El Camino Real de Tierra Adentro (literally, "the road to the interior" because the U.S. frontier was seen as the country interior to Mexico), the King's Highway and the Royal Highway. It became a transportation lifeline that helped integrate Spanish and European culture in the Southwestern U.S.

El Camino Real (The Royal Road) Eastern Branch

Historically, a camino real (Royal Road) is defined as a road that connects Spanish capital with Spanish capital, a distinction not shared with roads connecting ordinary Spanish or Indian villages. The term Camino Real implied that the status and privileges granted to the villas and capitals it connected were extended to the main routes of travel through use by officials and others acting in the interest of the crown. Unlike ordinary Indian and Spanish villages, villas like San Antonio and others along the route had charters that prescribed royal privileges.

Zuiderzee Enclosure Dam

The first Zuiderzee Enclosure Dam ran from North Holland to the island of Wieringen, successfully barring the sea for over 50 years and protecting a large area north of Amsterdam. The total Zuiderzee project was the largest land reclamation effort in the Netherlands, developed over a period of about 80 years, beginning in 1918 and reaching completion in 1996. The huge dyke/dam was considered one of the greatest engineering feats of its time.

White River Concrete Arch Bridge
Society: ASCE Main Category: Civil Sub Category: Bridges Era: 1930-1939 DateCreated: 1930 White River Cotter State: AR Zip: 72626 Country: USA Website: http://www.asce.org/Project/White-River-Concrete-Arch-Bridge/ Creator: Marsh, James Barney

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 United States Capitol is among the most symbolically important and architecturally impressive buildings in the nation. Construction of the original Capitol began in 1793, but it has been through several additions and alterations. Over its lifetime, the Capitol building has been built, burnt, rebuilt, extended, and restored.

The Triborough Bridge Project is a three-branched waterway crossing that connects Manhattan, the Bronx, and Queens at a junction of the East River and the Harlem River in New York City. The complex structure includes a suspension bridge from Wards Island to Queens, a vertical lift span from Randall's Island to Manhattan, a fixed span (designed to be convertible to a lift span) across the Bronx Kills, viaducts, and an innovative three-legged roadway interchange.

Sewall's Bridge

Sewall's Bridge is a singular example of an era when wooden trestle bridges carried highway traffic across New England waterways. It is the earliest pile-trestle bridge for which an authentic construction record exists, and the oldest for which builder's drawings survive. Spanning the York River, it was named for Major Samuel Sewall, Jr., the civil engineer who designed and constructed it.
