Interview with Program Manager Julie Allen

Concrete Pour on Bridge Project 

This month, we conducted an interview with Julie Allen, the Program Manager for the Sixth Street Viaduct Replacement Project, to learn more about her role leading the largest bridge project in the history of the City of Los Angeles:

What do you do on the project? 

Julie Allen: I am the Program Manager, which means I am responsible for leading the team that will deliver this project for the City of Los Angeles. This includes managing the design and construction, developing and monitoring the budget and expenditures, and obtaining concurrence and approval from numerous stakeholders.

When did you start working on the project? 

Julie: January 2015.

How do you overcome challenges that arise while you’re working?  

Julie: The City has an amazing team on this project including both the Bureaus of Engineering and Contract Administration. We work together and collaborate to address and resolve the many challenges that have arisen throughout the project. We have tremendous structural and construction expertise that has been instrumental in identifying and solving technical problems.

What’s helped you most while working on the viaduct? 

Julie: Given the size, complexity, and political exposure of this project, the guidance and support from the City Engineer, Gary Lee Moore, has been invaluable.

What motivates you to complete this difficult and challenging project?

Julie: Visualizing the completed viaduct, with the arches all lit up; with pedestrians, cyclists, and vehicles all safely utilizing the beautiful, new structure. That keeps me motivated to successfully deliver the project.

What’s your favorite part of the project?

Julie: Witnessing so many people from different agencies working together to create much-needed infrastructure, and the ability to leave a lasting, iconic landmark for many generations to appreciate and enjoy.


Starting at 4:00 a.m. on the morning of November 13th, our team completed an eight-hour concrete pour at Bent 7, at the juncture of Mission Road and Sixth Street. The pour was at the arch rib floor beam knuckles. 


About the Project

Stay Involved!

The Sixth Street Viaduct Replacement Project is constructing a new, 3,500-foot long viaduct connecting Boyle Heights and the Arts District across the Los Angeles River. The original viaduct was built in 1932, but had significantly deteriorated due to "concrete cancer"; it was demolished in 2016. The new viaduct will have ten pairs of lit arches, bike lanes and wider sidewalks, along with stairway access and bike ramps connecting to 12 acres of recreational and open space under the bridge. The $488 million dollar project is the largest bridge project in the history of the city. The bridge is funded primarily through the Federal Highway Administration, with additional City support. The viaduct will be completed in 2022.
