This stone bridge, one of Charles Schweinfurth's four bridges traversing Doan Brook and the parkway (today Martin Luther King Jr. Blvd.) alongside it, carries Wade Park Avenue. Grade separation was a popular principle of landscape architect Frederick Law Olmsted, whose ideas influenced Rockefeller Park designer Ernest Bowditch. A stone staircase enables pedestrians to ascend or descend at this point. | Creator: Detroit Publishing Company | Date: ca. 1908 | Source: Library of Congress Prints and Photographs DivisionDownload Original File
