The Carroll Street Bridge officially reopened to pedestrians and cyclists on June 15, restoring a vital connection across the Gowanus Canal in Brooklyn, New York. Closed since 2021, the bridge is a rare surviving retractile bridge originally constructed in 1889 and one of only four of its kind remaining in the United States.

H&H served as Engineer of Record for the reconstruction of the new eastern abutment supporting the historic bridge. The team designed and detailed the new concrete abutment, adjacent soldier pile and lagging walls with precast panels, and the moment/approach slab. Throughout the project, H&H coordinated closely with the New York City Department of Transportation and the Gowanus Remediation team to refine structural details and support efficient construction within a constrained urban environment.

“It was a great experience to work on this project, navigating the complexities of designing within a constrained work area,” said Corey Greco, Senior Bridge Engineer. “Even more rewarding is seeing the positive impact it has on the community through the reopening of Carroll Street.”

The reopening marks an important milestone for the surrounding community, restoring pedestrian and bicycle access across the canal while preserving one of Brooklyn’s most distinctive historic transportation structures. Congratulations to the H&H project team and all project partners on the successful reopening of this historic landmark.
