The mile-long St. Croix River Crossing has the second extradosed bridge to be built in the United States as its main unit. The structure was constructed by a joint venture of Ames Construction, which is featured in the Focus article on page 6. The link leads to the Project article in the Fall 2018 issue of ASPIRE® that describes in detail the St. Croix Crossing structure.
As mentioned in the Focus article on page 6, Ames Construction was a partner in a joint venture for the first Arizona Department of Transportation public-private-partnership project, the construction of the South Mountain Freeway (Loop 202). This website has details and photos of the project.
The Perspective article on resilient design on page 10 discusses the benefits of resilient design and how it differs from sustainability or green design. The Federal Emergency Management Agency’s Guidelines for Performance-Based Seismic Design of Buildings (FEMA P-58-6) can be downloaded from this website. Although the publication addresses seismic performance of buildings, the principles are also applicable to transportation structures and any hazard event.
This website has a video showing a bird’s eye view of the construction progression of the Wekiva Parkway Bridges, including those featured in the Project article on page 14.
The Concrete Bridge Technology articles on pages 28 and 32 discuss design and construction details of strut-and-tie models. This link is to an article from the Fall 2018 issue of ASPIRE® that explains the fundamentals of strut-and-tie modeling.
Bundling of bridge projects is discussed in the Federal Highway Administration (FHWA) article on page 42. FHWA’s recently published Bridge Bundling Guidebook can be downloaded from this website.
Based on a fall 2018 webinar, this FHWA document provides resources on project bundling. Bridge bundling is the subject of the FHWA article on page 42.
This Texas Department of Transportation website contains standard drawings for bridge construction, including prestressed concrete beams and railing details. The use of standard details as a costeffective measure is mentioned in the State article on page 50.
As mentioned in the LRFD article on page 54, Article 5.13 of the American Association of State Highway and Transportation Officials’ AASHTO LRFD Bridge Design Specifications has adopted the provisions for concrete anchorage from the American Concrete Institute’s Building Code Requirements for Structural Concrete (ACI 318-14) and Commentary (ACI 318R-14). Under the sponsorship of the National Cooperative Highway Research Program, PCI developed a fivepart webinar series for bridge engineers on the requirements for designing, detailing, and installing concrete anchors. This link provides access to a Dropbox folder that contains the recorded webinar series, course handouts, and resources.
