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 New Mexico Department of Transportation created this video of construction activities on the U.S. Route 54
Canadian River Bridge project. The three-span cast-in-place, post-tensioned segmental box-girder bridge is featured in the
Project article on page 24.
The American Segmental Bridge Institute’s Construction Practices Handbook for Concrete Segmental and Cable-
, third edition, is a “how-to” guide for the industry and is featured in the Concrete Bridge Technology
article on page 36. The handbook is available as a free download from this webpage.
The FHWA article on page 42 discusses available tests for alkali-silica reaction as well as a new, faster test being
developed by the Chemistry Research Laboratory at the Federal Highway Administration (FHWA) Turner-Fairbank
Highway Research Center. The FHWA’s Alkali-Aggregate Reactivity (AAR) Facts Book
(FHWA-HIF-13-019) is available
for download from this webpage.
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 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.
