The Selmon West Extension in Tampa, Fla., is the focus of the Project article on page 12 and the Concrete Bridge
Technology article on page 44. The segmental concrete structure is creative in its style and used a progressive spanby-
span erection technique. This link provides access to a presentation on the project given at the American Segmental
Bridge Institute’s (ASBI’s) Fall 2021 Convention. The video presentation includes an animation of the erection of the
precast concrete box segments using specialized equipment.
The Project article on page 22 features the replacement of the superstructure of the California State Route 99 over
21st Avenue Bridge in Sacramento County. The bridge could only be closed for a short period due to heavy commuter
and industrial traffic, so the demolition and removal of the superstructure was completed in 18 hours. This is a link to
a video of the removal of the last girder. The new bridge was reconstructed with 35 precast, prestressed concrete box girders.
Slag cement was a key component in the rehabilitation of the Lake Tillery Bridge, a historic arch bridge in North
Carolina featured in both a Project article (page 18) and a Creative Concrete Construction article (page 53). This is a
link to a web page with details of the slag cement mixture and the rehabilitation, as well as additional photos.
The FHWA article on page 68 discusses the use and standardization of building information modeling in the
transportation industry. This is a link to download the publication Demonstration of Bridge Project Delivery Using
(FHWA-HIF-21-031), the basis of the article.
In the Professor’s Perspective article on page 60, Dr. Tyler Ley of Oklahoma State University shares his vision for educating
the future workforce through YouTube. This is a link to his YouTube channel, which offers numerous videos on concrete materials and design.
This is a link to the ASBI archive of their monthly webinar series on topics such as “An Introduction to Today’s Concrete
Segmental Bridge Technology.” The Selmon West Extension is a concrete segmental bridge and is featured in both a
Project article on page 12 and a Concrete Bridge Technology article on page 44.

The American Association of State Highway and Transportation Officials (AASHTO) has released a
Specifications for Bridges Subject to Tsunami Effects
. With these guide specifications, designers now have a means to
quantify forces associated with a tsunami event. This is a link to the AASHTO online store, which provides the publication’s
table of contents and introduction in addition to purchasing information.
The report for the National Cooperative Highway Research rogram Synthesis 571 Load Rating of Bridges and Culverts with Missing or Incomplete As-Built Information
is available at this link. The report presents the current tate of practice and techniques (such as nondestructive
evaluation, load testing, and engineering judgment) used by tate departments of transportation for load rating of bridges
and culverts with missing or incomplete as-built information.
