In the early morning of March 26, 2024, the massive cargo ship Dali lost power as it left the Port of Baltimore. The ship collided with one of the supports holding up the Francis Scott Key Bridge over the Patapsco River and the bridge collapsed, killing six construction workers and severely disrupting the flow of people and goods around Baltimore. In the immediate aftermath of the tragedy, officials began the process of planning for a new bridge, and now UMBC students are getting an up-close look at the massive project.

A year and half later, three Retrievers visited the bridge site, observing as workers demolished parts of the remaining structures in preparation for building a new bridge. Emily DiMarzio, a rising junior studying environmental science and geography, and Cristian Mena and William McConnell, both rising seniors studying mechanical engineering, were all selected to join The Key Bridge Rebuild Internship Program this summer. While their trip to the bridge this August was partly photo-op, it also represented their experiences throughout the summer, which included regular trips to the bridge and surrounding sites to learn about the ongoing work there.

The Key Bridge internship program launched this year as a partnership between the Maryland Transportation Authority (MDTA) and the Maryland Higher Education Commission (MHEC). This summer nine students from four Maryland universities, including Retrievers DiMarzio, Mena, and McConnell, got hands-on experience in project management, environmental analysis, construction oversight, and community outreach.

“It hurt when the bridge went down,” says McConnell, who grew up in Baltimore and now lives with his wife and three kids in Catonsville. “You could practically see it from our neighborhood, and now see that it is missing. So when the opportunity came along to apply for this internship, I jumped on it.”

Bridge building boot camp

At the start of the internship, the students were divided into teams based on their interests. McConnell and Mena were on the structural and geotechnical team, which worked to review, analyze, and visualize data that was collected earlier in the year while boring into the layers of sediment where the structural supports for the new bridge will go. DiMarzio was on the environmental compliance team that performed reviews of permitting documents and requirements and observed how the requirements are met during construction.

A large part of the process was coming up to speed fast on the bridge-building process.

“I’ve learned so much—I feel like a bridge expert after this summer,” laughs Mena.

McConnell noted that all the interns on the structural and geotechnical team came from mechanical engineering backgrounds. “It was nice for us to be exposed to and learn a lot about the civil engineering field,” he says.

The interns went on regular trips outside the office to see the bridge-building process in action. They visited the Chesapeake Bay Bridge, which was being redecked, and visited the Key Bridge site multiple times.

They also visited the Turner-Fairbank Highway Research Center in McLean, Virginia, where they saw how researchers were testing a 3D model of the new bridge to better understand how the force of waves will affect the sand around the bridge’s supports.

“I thought that was super cool,” says Mena. “That was one of my favorite project sites.”

“The UMBC students are great to work with,” says Jason Stolicny, the deputy director of project development at MDTA who served as their supervisor this summer. “They show a genuine interest in learning and gaining exposure to new things.”

Community outreach

As part of the internship, DiMarzio, Mena, and McConnell also worked together to develop a hands-on workshop for students at Cherry Hill Middle School in Baltimore as part of the UMBC Summer Math Program through the George and Betsy Sherman Center. They prepared a presentation on different bridge types and the workers who come together to build and maintain them. They also worked with students to design and build model bridges. The workshop was part of a summer enrichment program that UMBC runs in partnership with Baltimore City Public Schools. The interns’ workshop fit into a curriculum about bridges that Malaysia McGinnis ’21, geography and environmental science, and M.A. ’24, secondary education and teaching, a teacher at Cherry Hill and Sherman Scholar, had designed for the summer program.

“There was one kid that stood out to me because during the whole presentation, he looked like he was asleep and so he kind of reminded me of myself,” says Mena. “So after the presentation I partnered up with him in the activity. He was super bright and answered all the questions I asked him. Hopefully, I inspired him to see his career choices and to continue learning and growing.”

MDTA plans to continue the Key Bridge internship program until the bridge has been rebuilt, which is currently anticipated to be in fall 2028.

“It was an honor to be part of the first group of interns,” says McConnell. “I hope we helped set the stage for future interns to have really great experiences too.”

Mena contemplates what it will feel like to see the new bridge spanning the river: “That’s going to be quite a sight. I think it’ll be pretty meaningful because even though I contributed in a very small way, it’ll stand in our community as something bigger than ourselves and a symbol of what we can do when we put our minds together.”
