Grand Central Terminal

Spearheaded by Chief Engineer William J. Wilgus and constructed under challenging conditions with no interruption of existing train service, Grand Central Terminal was a triumph of innovative engineering in the design of urban transportation centers. Its novel, two-level station, made possible by electric traction, streamlined both train and passenger movement by separating long-haul and suburban traffic and employing an extensive system of pedestrian ramps throughout the facility.

Lake Pontchartrain Causeway

In the 1940s and 1950s, New Orleans experienced growth. Unfortunately, access from the north to the City continued to be limited by Lake Pontchartrain. Driving around the Lake was a time consuming effort. During this time period, a renewed interest developed to provide a direct connection across the center of the Lake to the north shore. As a result, the Greater New Orleans Expressway Commission was formed to build the Lake Pontchartrain Causeway Bridge. The original bridge (southbound) was opened on August 30, 1956.

Newark Airport

In May 1927, the same month of Charles A. Lindbergh's famous transatlantic flight from New York to Paris, a fact-finding commission appointed by the U.S. Secretary of Commerce concluded that Newark would be the ideal location for an airfield to serve the greater New York/New Jersey metropolitan area.

Civic leaders wasted no time; construction began on the Newark Airport in January 1928. Nine months and $1,750,000 later, 68 acres of soggy marshland had been filled and converted to an 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:

The original wooden Union Bridge

The Union Bridge was built in 1804 by Theodore Burr and was the first to cross the lower section of the Hudson River connecting Waterford and Lansingburg, New York. The wooden bridge's key feature was the arch that started below the deck at the abutments and ran near the top of the top chord at mid span. This was the first time in the United States that anyone had used an arch in combination with a truss in order to provide both stiffness and strength. Burr later patented his truss/arch pattern in 1806 and 1817.

UTICA MEMORIAL AUDITORIUM

The roof system of this building, designed by Lev Zetlin and opened in 1960, was the first of its kind in the world. Before the mid-1950's, the use of long-span cable structures was generally limited to suspension bridges. The only other significant cable roof structure preceding the Utica Memorial Auditorium was the North Carolina State Fair Livestock Judging Pavilion, completed in 1953.

The Dalles Lock and Dam

The Dalles Lock and Dam was one of the largest, most complete, and complex multipurpose projects of its kind in the United States at the time of its construction. It provided an example for future projects benefitting navigation, recreation, water for irrigation and hydropower, fish migration, and flood mitigation. The unusual "L" configuration of the project enabled reduced construction dewatering and created a permanent shallow stilling basin that aids fish passage.

Taken together, the 1940 and 1950 Tacoma Narrows bridges mark a significant turning point in the design of long-span suspension bridges. The original 1940 structure was designed with one of the shallowest and narrowest stiffening elements of any long-span suspension bridge yet built. The structure failed dramatically in a rather moderate 42 mph windstorm on 7 November 1940, only four months after opening for traffic.

On October 23rd, 1852 a notice was sent to practitioners of civil engineering in and near New York City requesting their participation in developing an association that would serve the professionals who design and construct America's built environment. Twelve men responded to this invitation, meeting on November 5 in the office of Alfred W. Craven, chief engineer of the Croton Aqueduct  Department. These men became the founders of the American Society of Civil Engineers and Architects, later renamed the American Society of Civil Engineers (ASCE).
