The Marc Basnight Bridge at North Carolina’s Outer Banks is mentioned in the Focus article on specialty post-tensioning contractor Schwager Davis Inc. on page 6. The bridge is 14,800 ft long with 11 spans of post-tensioned segmental concrete box girders and 71 spans of prestressed concrete girders. It was featured in Project and Concrete Bridge Technology articles in the Fall 2019 issue of ASPIRE®. Both articles can be found at this link.

The Concrete Bridge Preservation article on page 46 provides an overview of externally applied fiber-reinforced-polymer composites and their applications, limitations, and design considerations. The article also discusses international design guidelines, including Externally Applied FRP Reinforcement for Concrete Structures, Bulletin 90, published by fib (International Federation for Structural Concrete). This webpage provides a link to the detailed table of contents and information for purchasing the bulletin.

As mentioned in the LRFD article on page 50, Article 5.13 of the American Association of State Highway and Transportation Officials’ AASHTO LRFD Bridge Design Specifications has incorporated by reference the provisions for anchoring to concrete from the American Concrete Institute’s Building Code Requirements for Structural Concrete (ACI 318-14) and Commentary (ACI 318R-14). Under the sponsorship of the National Cooperative Highway Research Program, PCI developed a five-part webinar series for bridge engineers on the requirements for designing, detailing, and installing concrete anchors. This webpage provides a link to access to a Dropbox folder that contains the recorded webinar series, course handouts, and additional resources.

The Concrete Reinforcing Steel Institute has a free mobile app, “Rebar Reference,” which can be obtained at this link. The app, available for both Android and iOS mobile devices, serves as a ready reference guide and provides general information pertaining to steel reinforcement. The features of the mobile app are described in detail in the Concrete Bridge Technology article on page 38.
