I-78 PA Metric (Pennsylvania) (Road Sign) T-Shirt: Design
This t-shirt showcases a bold and ironic design centered around the non-existent I-78 PA Metric road sign. The artwork immediately grabs attention by presenting a familiar element: a standard Interstate highway shield. The iconic red, white, and blue shield, instantly recognizable as signifying an Interstate highway, forms the foundation of the design.
The core of the design cleverly subverts expectations. Instead of the expected imperial units (miles) and distance markers in miles, the sign boldly displays the number "78" in large white numerals, representative of Interstate 78. However, the background is intentionally designed to evoke the illusion of a metric sign, with kilometers highlighted. This deliberate contradiction creates a visual paradox, immediately signaling the historical absence of metric signage on I-78 in Pennsylvania and throughout the United States (except for the very limited case of I-19 in Arizona).
The design’s symbolism lies in its playful commentary on American history and the resistance to adopting the metric system. The presence of "78" in the design is a declaration of the road's identity, while the "Metric" wording is a wry nod to what never was. The absence of kilometers symbolizes the historical rejection of the metric system in American road signage, and the design's humorous tone adds a layer of irony, making it a conversation starter for road enthusiasts and history buffs alike.
