Description

Education Session #7: TRRA Merchants Bridge Main Span and East Approach Replacement/Retrofit
The presentation covers the history and design phase of the TRRA Merchants Bridge over the Mississippi River in St. Louis, MO. The 3 main truss spans being replaced over the main channel measure 520' in length and will open traffic again to 2 tracks. The east approach steel trestle spans were filled with light-weight cellular concrete providing an innovative solution to minimize rail traffic interruptions.
Nick Staroski, P.E., S.E., TranSystems

Education Session #8: Hanging on to the Past - Modeling and Load Rating of Existing Pin & Hanger Bridges
Catching popularity in the early 1900’s, steel pin and hanger bridge assemblies became an efficient and common way to design steel bridges. However, the Mianus River Bridge collapse in 1983 infamously highlighted that these fracture critical members are prone to catastrophic failures. This presentation will discuss how to evaluate and maintain structures with these details by focusing on behavior, modeling requirements, and load rating methods.
Mateusz Pec, and Enji Paul Papazisi, P.E., HNTB

Pearl Session #3: California High Speed Rail Construction Package 2-3 – SR-43 Concrete Tied Arch Bridge
The California High Speed Rail Construction Package 2-3, delivered currently under a design/build project, provides for over 65.5 miles of high-speed rail infrastructure through California’s Central Valley from Fresno to Bakersfield. Designed for a high-speed rail of 250 mph, the project includes several unique concrete bridge types, among them a concrete network tied arch bridge selected to satisfy very tied horizontal and vertical clearance requirements as it spans over SR-43 while maintaining highway traffic below.
Hadi T. Al-Khateeb, PhD, P.E., S.E., Jacobs

Education Session #9: Frances Appleton Pedestrian Bridge, A Case Study in Leveraging Cast Steel Connections for the US Steel Bridge Community
The award-winning Frances (Fanny) Appleton Bridge is an elegant steel bridge with an exemplary combination of functionality and esthetic value with use of state-of-the-art technologies adeptly executed through collaboration among all members of the expert design and construction team. This presentation will demonstrate how castings can be successfully incorporated into construction to support the US steel bridge community in realizing exceptional projects. Lessons learnt from the project will illustrate how the resources being developed by the new AASHTO/NSBA TG17: Steel Castings will accelerate adoption and successful use of cast steel connections in design and construction of bridge structures in the US.
Matthew Conso, EIT, CWI, and Jennifer Anna Pazdon, P.E., MASSDOT/Cast Connex
