In Arcadia, a steel railroad bridge transitioned the Atchison, Topeka and Santa Fe Railway between the I-210 and street grade. This bridge, between Baldwin and Santa Anita, was deemed unsafe following the 1994 Northridge earthquake and removed by Caltrans. The Phase 2A project constructed the "Iconic Freeway Structure or Gold Line Bridge" (IFS), as the replacement bridge. Designed by Minnesota artist Andrew Leicester, the bridge was unveiled in December 2012. Leicester's design was chosen from 17 others in a competitive process. The artist worked with L.A. design consultant AECOM as well as the bridge's builder, Skanska USA, on the final design and construction. The woven-basket look of the bridge's support columns emulate the woven baskets of the native Chumash people of the San Gabriel Valley while the underside of the bridge evokes a Western diamondback rattlesnake.
