Tsunamis might be infrequent and localized, but their impact on coastlines can be catastrophic. Over the past 10 years, engineers have been gearing up to better prepare structures and communities for inundation. With the inclusion of tsunami-resistant design provisions in the Minimum Design Loads and Associated Criteria for Buildings and Other Structures, ASCE/SEI 7-16 and the adoption of this standard into the 2018 International Building Code, as well as the design and construction of the first structures to meet these codes, their work has been rewarded.

Conducted as part of a unique public-private partnership, the recently completed $1.4-billion upgrade of a nearly 6.5 mi long section of Interstate 35W in Fort Worth helps reduce congestion along a busy transportation corridor. Part of the regional system known as the North Tarrant Express, the project adds managed toll lanes and expands and renovates existing highway infrastructure, all of which will be managed by a private entity for decades to come.
