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 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.
