The 106-span Pensacola Bay Bridge replacement is the focus of the Project article on page 20. This is a link to the official
project website, which has several videos composed of animations, film, and renderings showcasing construction
activities, in-service experiences, and community outreach programs related to the project.
This is a link to a YouTube video of the virtual public meeting for the Massachusetts Department of Transportation
Acceler-8 Interstate 90 project, held on February 9, 2021. The meeting presents, in detail, project aspects and schedule.
The project, which used accelerated bridge construction techniques, is the focus of the Project article on page 24.
Concrete repair is a topic of both a Concrete Bridge Technology article on page 40 and a Concrete Bridge
Preservation article on page 34. The American Concrete Institute (ACI) has published several Repair Application
Procedures (RAP) bulletins authored by ACI Committee E706 Concrete Repair Education. This link provides access to
RAP-6: Vertical and Overhead Spall Repair by Hand Application
. Other bulletins include RAP-1:
Repair by Epoxy Injection
, RAP-4: Surface Repair Using Formand-Pour Techniques
, and RAP-8:
Installation of Embedded
The County article highlighting Clare County, Mich., on page 37 presents the use of a generic ultra-highperformance
concrete developed by a University of Michigan research program funded by the Michigan Department
of Transportation. This is a link to download the research program and field study report,
Commercial Production of
Non-Proprietary Ultra High Performance Concrete.
The Concrete Bridge Technology article on page 40 describes how the North Carolina Department of Transportation
(NCDOT), with the assistance of local precasters, has implemented standard repair procedures for certain
fabrication defects in precast concrete members. This is the link to a NCDOT web page that lists these standard repair
procedures and their applications. Other state agencies may have similar standard repair protocols or procedures.
The Professor’s Perspective article on page 52 describes the precast concrete curriculum at Idaho State University. The studio
concept for precast concrete education was developed by the PCI Foundation. This website showcases activities of various
studios at universities across the country and gives access to educational aids for all instructors interested in precast concrete.
The Perspective on page 10 discusses how life-cycle assessments can be an important tool in moving toward carbon neutrality
for concrete structures. This is a link to the life-cycle assessment webpage on the Massachusetts Institute of Technology
Concrete Sustainability Hub website. The page contains links to news, research, and webinars relating to life-cycle assessment.
The Sargent Beach Bridge is featured in a Project article on page 18. The bridge used a spliced girder to span 300 ft, and the
drop-in girder was temporarily supported by embedded steel corbels. This concept was also used on the Phoenix Sky Harbor
Airport’s Sky Train bridge. Details of that project are described in a Concrete Bridge Technology article in the Summer 2020 issue
. This is a link to download the article.
The Spring 2022 issue of ASPIRE® included both a Project article and Concrete Bridge Technology article on the Selmon
West Extension in Tampa, Fla. This is a link to the American Segmental Bridge Institute monthly webinar page, which
provides access to a recorded webinar on the design and span-by-span erection of the project’s extradosed finback
This is a link to a memorandum issued on April 18, 2022, by the Office of Management and Budget to provide
implementation guidance to federal agencies and other entities of the revised “Buy America” rules for infrastructure
projects. The memorandum also outlines how aspects of the Infrastructure Investment and Jobs Act are affected.
The American Association of State Highway and Transportation Officials (AASHTO) has published the second
edition of the LRFD Guide Specifications for Bridges Carrying Light Rail Transit Loads.
This new edition of the guide
specifications clarifies live loading and derailment loading and improves alignment with the
AASHTO LRFD Bridge
, ninth edition, with which they are to be used. This is a link to the AASHTO online store, which
provides the publication’s table of contents and introduction, in addition to purchasing information.
