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.
The Project article on page 16 presents a 10 mile U.S. Route 2 rehabilitation effort in remote northern Montana, which includes several bridge rehabilitation and replacement projects. This is a link to the plans for the Lohman E & W 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.
The Interstate 90 Acceler-8 project in Massachusetts, described in the Project article on page 24, used Northeast Extreme Tee D beams to reduce project costs and accelerate construction. This is a link to the Northeast Extreme Tee (NEXT) Beam web page on the PCI Northeast website.
The repair of the West Seattle Bridge is one of the case studies presented in the Concrete Bridge Preservation article on page 28. This is a link to a Seattle Department of Transportation web page that provides information on the repair project, including a narrated video. The web page also includes links to the bridge replacement study, additional repair videos, and detour information..
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: Structural Crack Repair by Epoxy Injection, RAP-4: Surface Repair Using Formand-Pour Techniques, and RAP-8: Installation of Embedded Galvanic Anodes.
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 FHWA article on page 58 is based on the Federal Highway Administration report Truck Platooning Impacts on Bridges: Phase I–Structural Safety (FHWA-HIF-21-043). The report can be downloaded via this link.
The FHWA article on page 58 explores the effects of truck platooning on bridges. This link accesses an FHWA article in the Summer 2019 issue of ASPIRE that describes the truckplatooning concept.
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 of ASPIRE. This is a link to download the article.
