| 摘要： | Originally constructed from 1924 to 1928 to span the Allegheny River in Pittsburgh, Pennsylvania, they were the first self-anchored suspension bridges constructed in the U.S. and remain the only trio of identical, side-by-side bridges in the world. Listed on the National Register of Historic Places, the Three Sisters Bridges are virtually identical in appearance and feature unique aesthetic characteristics. The original pylons and dedication plaques, for example, were designed by Stanley L. Roush, architect of many of Pittsburgh's iconic bridges and buildings constructed in the early 1900s. For decades, the three bridges were simply called the 6th Street, 7th Street, and 9th Street Bridges. The 6th Street bridge has since been renamed the Roberto Clemente Bridge, in honor of the Pittsburgh Pirates legend. The 7th Street and 9th Street bridges have been renamed to honor Pittsburgh natives Andy Warhol and Rachel Carson, respectively. |
