Pearl Harbor Memorial Bridge: Innovative Design Wins Awards, Moves More People
The original “Q Bridge” was built over the Quinnipiac River in New Haven, Conn., in 1958, but within 30 years its six lanes were insufficient for the growing traffic. Shortly before it was officially dedicated as the Pearl Harbor Memorial Bridge in 1995 (to commemorate the attack on Pearl Harbor), local officials had decided it was time to replace the structure with a new bridge. For two decades the Connecticut Department of Transportation (CONNDOT), the Federal Highway Administration, the...

The airport built to support this production is considered by some historians to be the first modern airport. Though no longer used to make...
A High-Visibility Project: Examining the Historic and Beautiful New Portageville Bridge
By Mark Scacco, P.E. In 1852—the year women were being arrested for wearing pants (Emma Snodgrass in Boston) and the first edition of Peter Roget’s Thesaurus was published—the Erie Railroad Company built the first bridge to cross the Genesee River Gorge in what would eventually become Letchworth State Park in Western New York, about 60 miles east of Buffalo. Claimed to be the world’s largest timber bridge, it served the rail line until it burned to the ground in May 1875. In June and Jul...
The Right Tool for the Job: Multiple Tools Complicate Reality-Capture Landscape
When it comes to capturing existing conditions, the first question in everyone’s mind seems to be “to scan or not to scan?” With all the technologies out there, the next question is usually “which tool is best for the job?” Complicating the ability to answer these questions is the accelerated pace at which new technology developments and commercially available products enter the market. When overwhelmed by choices—especially new, unproven and expensive options—we’re often moved to inaction, m...
Battling Corrosion Problems in Harsh Middle East Environmental Conditions
Figure 1. Migrating corrosion inhibitors form a protective layer on the surface of embedded steel reinforcement. By Julie Holmquist Harsh environmental conditions create an added challenge to the durability of structures in Middle Eastern regions such as the United Arab Emirates (UAE) and Qatar.

Manhattan’s Irish Hunger Memorial Receives Waterproof Renovation
