The 3,500–foot long 6th Street Viaduct is a transformative landmark in Los Angeles constructed in 1932. Concrete elements of the original viaduct cracked and deteriorated over the next 75 years as a result of an internal Alkali Silica Reaction (ASR) caused by the reactive aggregate used in the concrete. Because of this ongoing and irreversible chemical action, it was determined that replacement was necessary during seismic vulnerability studies that determined the structure was susceptible to failure during major seismic activity. Additional geometric design, safety and functional deficiencies resulted in the decision to demolish and replace the bridge with a new 6th Street Viaduct. Presenters will discuss how the project met the following goals:

• Preserve 6th Street as a viable east-west link between Boyle Heights and Downtown Los Angeles
• Reduce vulnerability of the 6th Street Viaduct in major earthquake events
• Integrate the viaduct with the surrounding community
• Increase the role and functions of this urban viaduct
• Enhance and encourage multi-modalism transporation
• Resolve design deficiencies of the 6th Street Viaduct

Carbon capture, utilization and storage (CCUS) encompasses proven technologies that have been used in some sectors for decades as well as new, disruptive technologies that have yet to be commercialized. However, CCUS has yet to be deployed widely at scale. Despite economic challenges, the future of CCUS looks more promising than ever due to net-zero goals set by governments and corporations worldwide. This presentation will explore different types of CCUS technologies used in heavy industries like power, steel, cement and oil and gas and how the existing market drivers are helping to create a more sustainable world.

Part 1 of this 2-part webinar takes a look at how justice, equity, diversity, and inclusion intersect with the infrastructure industry. Their importance and relationship with each other is explored, while the process of how to achieve and measure equitable outcomes is provided.

Part 2 begins by comparing and contrasting how various infrastructure sectors were affected by the shock of COVID-19, before focusing on how an emphasis on resilience is required to safeguard infrastructure assets from future "black sheep" events.
