The bollards are illuminated and contain graphics that relate to elements in an interpretive video created for the Welcome Center. Visitors to the Welcome Center will first view the video and then be able to experience the Loess Hills of Iowa via the walking trail west of the building. Visitors will also be able to relate elements seen in the video to the same scenes portrayed in six interpretive bollards along the trail. Large, dynamic interpretive signs and graphics educate visitors and showcase significant landmarks of Harrison County. The Lincoln Highway panel describes the historical impact of the road on the nation, and how it led to the intricate interstate system that we have today. The Loess Hills graphics educate the public about the vast plant and animal species that have created a habitat within these hills.   Strategically located to seize views of the transportation corridor including the Lincoln Highway and railroad, the outside artwork speaks to the main story line of the history of the Lincoln Highway, crossing 13 states in 3389 miles, established in 1913. Functional railing sections serve as sculptural signage and a marker element on the site.
