Frederick Douglass-Susan B. Anthony Memorial Bridge

Erdman Anthony provided preliminary and final design services for the reconstruction of and capacity improvements to 3.5 miles of I-490, a major six-lane highway that bisects Rochester, including 20 bridges in this section from the Erie Canal to the Genesee River. As part of this project, Erdman Anthony designed the Frederick Douglass-Susan B. Anthony Memorial Bridge (Troup-Howell Bridge) as a replacement for the existing bridge. The new bridge is 1,180 feet-long, with an arch span of 433 feet. The three-member steel arch structure is the first of its kind in the United States. Design features contributing to the bridge's appeal include a low profile that enhances sight distance along I-490, rounded support beams and cable support linkages to enhance visual interest, and a fanned array of support cables to echo the shape of the arch.
