PITTSBURGH — A city bridge was renamed in honor of Rachel Carson, a major figure in the modern environmental movement.

City council voted Tuesday to rename the Ninth Street Bridge the Rachel Carson Bridge.

Carson, a native of nearby Springdale Borough and author of "Silent Spring," was named by Time magazine as one of the 100 most important people of the 20th century for her work.

"She gives us the vocabulary to help us articulate questions and understand our world better," said Nancy Gift, acting director of the Rachel Carson Institute at Pittsburgh's Chatham College, Carson's alma mater.
