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.

The San Jacinto Monument commemorates the decisive 1836 battle near the banks of the Buffalo Bayou and the San Jacinto River that allowed Texas to win independence from Mexico. It is the world's tallest monument, rising 15 feet higher than the Washington Monument.

In 1936, Daughters and Sons of the Republic of Texas led lobbying efforts to allocate funds for a monument that would mark the importance of the Battle of San Jacinto. Ground was broken on April 21, 1936 - 100 years to the day after the victorious battle.

Ever since the Gold Rush days of the 1850s, San Francisco Bay area residents and businesses had lobbied for a bridge joining San Francisco and Oakland. Early studies indicated that the bridge was impractical and infeasible; but in October 1929, President Herbert Hoover (himself an engineer) and California Governor C. C. Young appointed the Hoover-Young San Francisco Bay Bridge Commission to study the question more closely.

The Port Washington Power Plant of the Wisconsin Electric Company was the most thermally efficient steam power plant in the world for many years following its opening in 1935. Its design reflected the cumulative experience of the utility's engineers in burning pulverized coal at the Oneida Street Plant and the Lakeside Station in Milwaukee.

Norris Dam impounds the Clinch River, a mountain tributary of the Tennessee River. The facility stands as a tribute and symbol of the birth of the Tennessee Valley Authority (TVA). Given broad jurisdiction over resource development in the watershed (a 40,000-square-mile basin comprising parts of Virginia, North Carolina, Georgia, Alabama, Mississippi, Kentucky, and Tennessee), the TVA was formed to plan for flood control, improve navigation, and produce hydroelectric power.
