Illinois Interstate 55 highway marker sign

Description

If there is one road serving as Illinois’s main street today, it is surely Interstate 55. It follows the path of the historic Route 66, cutting diagonally across the state from the Mississippi River in the southwest to just short of Lake Michigan in the northeast. Interstate 55 is a vital part of Illinois’s transportation network, connecting the St. Louis and Chicago metropolitan areas to the state capital, Springfield. In Illinois alone, the route is nearly 300 miles (473 km) long.

Celebrate a true icon of American highway history with this Illinois Interstate 55 route sign, meticulously recreated to the exact 1957 standards from the dawn of the Eisenhower Interstate Highway System. Long before today’s simplified shields—which often have the state name stripped from them—this bold, classic design defined an era. Originals are becoming increasingly rare, which makes this faithful reproduction a must-have for collectors, decorators, and transportation history enthusiasts.

Unlike cheap imitations that cut corners on materials and accuracy, this Illinois Interstate 55 sign is crafted with uncompromising attention to detail. There’s no flimsy tin, no incorrect fonts, no distorted layouts—only a museum-quality piece that looks just as stunning up close as it does from across the room. Even the most discerning collector will be tempted to lean in and admire the precision.

Our Illinois Interstate 55 sign is flat printed on heavy-duty 14-gauge steel, featuring completely accurate fonts and layout based on original specifications. The finish is non-retroreflective and protects the sign from the elements, making it ideal for both indoor and outdoor display. Pre-drilled mounting holes ensure quick, easy installation. Available sizes include:

• 12 in. × 12 in. – Perfect for decorators with limited space or budget
• 18 in. × 18 in. – The smallest size specified in the original 1957 signage manual
• 24 in. × 24 in. – A common modern display size
• 36 in. × 36 in. – Oversized for maximum visual impact and visibility
