A trip along Canal Street is a front row seat to Chicago’s rich history as a transportation hub. From Union Station to the old Post Office, ornate landmarks speak to the architecture the city is so proud of. The Canal Street Bridge is one of those marvels – built in 1914, the railroad bridge is the only vertical-lift bridge that spans the Chicago River, able to be raised up 111 feet to allow river traffic below to flow uninterrupted. A true feat of engineering, as is the frame that shares its name. Carved from rich acetate, rounded endpieces transition seamlessly into sculpted temples, proving once again that form and function work together beautifully to create a frame perfect for everyday wear.
