Bridge Rehabilitation and Replacement: Engineers Explain Methods Used on the Seabrook Strauss Bascule Bridge
By Gregory P. Taravella, P.E., and James W.H. Costigan, E.I. The Seabrook Bridge is a Strauss Heel-Trunnion Bascule Bridge located in New Orleans and owned by the Port of New Orleans. Built in 1923, the through-truss bridge originally carried two railroad tracks inside the trusses and two single-lane roadways cantilevered outside the trusses.

An Olympian Achievement: Los Angeles Zeroes in on Emissions-Free Bus Fleet
When Los Angeles hosts the Summer Olympic Games in 2028, city officials are hoping its zero-emissions bus fleet will share a bit of the spotlight with the world’s best athletes. Los Angeles Metropolitan Transportation Authority (Metro) is starting the journey to create a comprehensive Zero Emissions Bus Program through an analysis of its network of 165 bus and bus rapid-transit routes and 12 maintenance facilities. The goal is to convert to a complete zero-emissions bus fleet by 2030. To a...
Stormwater Management System Protects University of Michigan Campus
The system protects university buildings from potential floods while benefiting the environment and the city of Ann Arbor. The University of Michigan’s Central Campus is a gathering spot for students and visitors. It’s also a stormwater collection point in the downtown Ann Arbor, Mich., area, particularly during large storm events. A new underground stormwater infiltration system was designed to protect the campus and adjacent historic buildings from a 100-year storm event while pr...
Four Places Putting Green Infrastructure to Work for Local Communities
Figure 1. A map shows areas that would be flooded by 1.5 meters of sea-level rise, which is how much sea levels could rise by 2100 if emissions aren’t curtailed. By Emily Cassidy and Suzanne Ozment Water is a source of growing tension and violence in places where it’s scarce. At the same time, sea-level rise and flooding threaten millions of people living near coastlines and low-lying areas. Traditional infrastructure such as concrete dams and seawalls isn’t sufficient to...

Building a Smarter City: Baton Rouge Shows that Bigger Isn’t (Necessarily) Better
According to the IESE Cities in Motion Index, New York City, London, Paris and Tokyo topped the list of the world’s “smartest cities” in 2018. When megacities (with populations of more than 8 million) top these types of rankings, it’s easy to lose sight of the areas of real opportunity. In fact, much of the innovation and explosive growth in the Smart City arena is happening in small and midsize cities. This makes sense. Although megacities have the staff and budgets to really embrace some...
CAVTEC Moves Connected and Autonomous Vehicles Forward
Smart mobility solutions—such as connected infrastructure, autonomous vehicles, data-driven mobility and intelligent transport systems—are gaining ground in the transportation industry. To further these emerging smart mobility solutions, Space Institute Research Corp. (SIRC), an independent research and development organization at the University of Tennessee Space Institute (UTSI), recently partnered with Stantec to develop the Connected and Autonomous Vehicle Technology Evaluation Cente...
Grid Modernization Will Require Active, Holistic Network Management
As concerns about aging infrastructure in the electric industry fester, the promise of grid modernization is gaining increasing sway as power suppliers pursue optimized uptime and resilience while satisfying consumer cravings for lowered carbon footprints. Utility business models are changing to accommodate growing volumes of renewable energy coming onto the grid. New services are being demanded by customers, and new and divergent forms of energy are testing the flexibility and capacity of th...
Reef Re-Creation for Shoreline Protection
The Terrebonne Bay Shore Protection Demonstration Project points to one technique to help reduce shoreline erosion as well as promote oyster reef building. As climate change and subsidence begin to endanger America’s coastal communities, city and state governments are struggling to stand their ground as it literally sinks below them. Larger cities such as Miami and Atlantic City are constructing seawalls and water pumps to fight back against the rising waters, but community member...
Mobile 3D Scanning Technology Gaining Traction in Home-Renovation Market
A complete 3D point cloud of an entire property is viewed in CloudCompare. As residential real estate prices continue to climb in many parts of the United States, property owners are increasingly investing in renovations and additions to their existing homes. To meet the demand, architects seek digital as-built documentation of the structures so they can design the new construction. Many are asking for mobile 3D scanning by name as the technology they prefer to quickly capture the...
