New art pieces at Idaho’s first diverging diamond interchange showcase that the Chubbuck interchange is one of a kind. The $10.8 million project connects U.S. 91/Yellowstone Highway over the I-86 system. The metal art pieces adorning the interchange include a moose, a pronghorn and several birds of prey. “We worked with the contractor on design. They worked with a Utah artist who translated our ideas into fabricated pieces,” said Alissa Salmore, Idaho Transportation Department’s Region 5 senior environmental planner. Additional bridge aesthetics included concrete color for the parapet, piers, island paving and retaining-wall panels.
