Education Session #4: US 54 Canadian River Bridge, Logan, New Mexico
The new US54 Canadian River Bridge is an exciting first for the state of New Mexico and a new chapter for the area’s transportation future: A Cast-in-Place segmental bridge. This bridge, built in balanced-cantilever method, is designed to replace the 1954 fracture-critical steel truss structure while also minimizing impacts to the Canadian River, the river’s protected inhabitants, the surrounding wetlands as well as adjacent historic and pre-historic archaeological sites.

Education Session #5: Jefferson-7 Bridge Bearing Replacement Evaluation
This presentation introduces the complex structural analysis and evaluation to a 7-span highly skewed highway bridge with tall piers. Some rocker bearings are deteriorated, some are extremely tilted. The goal was to investigate the possible causes of the bearing issues and evaluate the structural safety during the bearing jacking and replacement.

Pearl Session #1: Guidance for Navigating Routine Steel Bridge Design
Engineers frequently report having trouble finding and properly addressing all the various design provisions within the AASHTO Bridge Design Specification. As a result, it has been more difficult and time-consuming to design routine steel I-girder bridges, easier to make mistakes in the calculations, and harder to find those errors during checking. This presentation is intended to introduce bridge engineers to the new “Navigating Routine Steel Bridge Design” guide developed specifically to address this issue.

Education Session #6: A Bascule Within a Bascule: Replacement of the Hinged Sidewalk on Lake Shore Drive Bascule Bridge
This presentation discusses the out of box innovation to widen the existing sidewalk from 8 feet to 20 by tunneling through the existing bridge houses and designing a bascule within a bascule for each leaf. The presentation focuses on the iterative design process the project team used to develop the hinged sidewalk replacement to allow for the lakefront trail widening over the Chicago River.

Pearl Session #2: Transition in Superelevation: I-490/I-90 Interchange Ramp Bridges
This presentation shares the design and construction of the two ramp bridges over I-90 as part of a new trumpet interchange to provide full access between existing I-90 and proposed I-490. Key accomplishments were: delivering the design and contract documents on an accelerated schedule, optimizing the structure alignment and type for efficiency and economy, accommodating superelevation transitions on the bridge decks, and utilizing design details that reduce future maintenance needs of the bridges.
