The 2016 ornament celebrates the 100th anniversary of the "Cyrus Avery Route 66 Memorial Bridge", the 11th Street bridge.
It was the first auto route across the Arkansas river and first major multi-span concrete bridge in Oklahoma, replacing a wooden wagon bridge. In 1996, it was added to the National Register of Historic Places.
The back piece shows a close view of one of 18 graceful, concrete arches spanning the river. Art Deco details are shown in the guardrails and lights.
The front piece shows the bronze sculpture titled "East Meets West", located in the adjacent Cyrus Avery Centennial Plaza. Created by Robert Summers, it depicts the Avery family riding west in a Model T encountering an east-bound horse-drawn wagon.
