The construction of this segment involved replacing a steel railroad bridge at the point where the Atchison , Topeka and Santa Fe right-of-way departed from I-210 in Arcadia . Caltrans deemed the structure unsafe following the 1994 Northridge earthquake , and it was replaced by a new structure known as the '' ' Gold Line Bridge , ' '' designed by Minnesota artist Andrew Leicester . The woven-basket look of the bridge 's support columns emulate the famed woven baskets of the native Gabrielino/Tongva of the San Gabriel Valley while the underbelly of the bridge is supposed to evoke a Western diamondback rattlesnake
