Replacing an Icon
Since 1852, the Portage Viaduct has carried a rail line across the Genesee River Gorge, near the town of Portageville, New York. First made of timber, then replaced with a wrought iron structure after...

Bridging the Genesee River Gorge Has a Complex History (part of "Replacing an Icon")
In the early 1850s, the Buffalo and New York City Railroad, a subsidiary of what would later be known as the Erie Railroad, expanded westward from the New York City area toward Buffalo, New York. As part...

Teaching Cars to Drive
The Michigan-based American Center for Mobility is located at a former World War II bomber factory, later an auto plant, that was environmentally challenged after decades of industrial use. Though the...

A Ladder At Its Core
The ladder-core system is a novel structural system for supertall towers that was created by SOM for Tower 1 at Shum Yip Upperhills, a mixed-use development in Shenzhen, China. The system features eight...

Civil War and Labor Strikes: The Baltimore and Ohio Railroad Martinsburg Shops
The B&O roundhouse complex in Martinsburg, West Virginia, contains key examples of America's 19th-century railroad infrastructure—and was ground zero for America's first national strike....

Artificial Intelligence Boosts Engineering Tech
Artificial intelligence is boosting a variety of emerging engineering technologies, ranging from applications that record and identify archaeological remains to roadway damage and urban blight....

Tunnel Safety (part of "Transformative Tunnel")
As part of meeting the stringent safety requirements of the Washington State Department of Transportation (WSDOT), the State Route 99 tunnel is designed to be one of the safest ever constructed, with state-of-the-art...

Dry Dams in the Desert: Chasing Land Subsidence and Earth Fissures with Geophysics
Homogenous embankment dam flood retention structures (FRSs) were built throughout central Arizona desert basins in the mid-twentieth century to protect mostly agricultural lands and military installations...

Avoiding Impacts of Collapsed Mines on Railways: A Multidisciplinary Geophysical Detective Approach
The presence of abandoned mine workings can pose a significant risk to the use and development of surface structures above them, including railway lines. Typically, the adverse and often sudden effects...

A Good Cause for a Causeway: How Geotechnology and Project Delivery Restored a Roadway Embankment Crossing a Historically Challenging Soft Ground Site
As part of a Minnesota Department of Transportation (MnDOT) design-build project, a causeway was constructed in 2017 to replace an aging bridge in the southwest metropolitan area of Minneapolis. The causeway...
