TL;DR
In 2014, Marcin Wichary documented a day chasing Chicago’s historic movable bridges, showcasing their engineering marvels and cultural importance. This report details the event, confirmed facts, and its relevance.
In April 2014, Marcin Wichary and a team of enthusiasts spent a day exploring and documenting Chicago’s historic movable bridges, capturing their mechanical beauty and operational details firsthand. This event highlights the city’s rich engineering heritage and ongoing fascination with these structures, which remain vital for transportation and cultural identity.
Wichary’s account details a day spent following the sequence of Chicago’s 27 movable bridges, including bascule and lift bridges, as they opened and closed to allow boat traffic. The exploration began at the Ashland Avenue Bridge and included notable sites such as the Cermak Road Bridge, Canal Street Bridge, and the historic Randolph Street and DuSable Bridges. The team coordinated with bridge operators, observing the precise mechanical ballet involved in their operation.
Confirmed facts include the mechanical design of these bridges, many of which were built over a century ago, and their reliance on carefully balanced counterweights that require minimal motor power. The Amtrak rail bridge, with its unique lift design, was also documented. Wichary’s team even gained access inside some bridges, observing control rooms and witnessing the operation up close, including standing next to a rising road deck.
Why It Matters
This exploration underscores the engineering ingenuity of Chicago’s historic bridges, many of which are over 100 years old yet still operational. For readers, it highlights the importance of preserving such infrastructure as both functional assets and cultural landmarks. The bridges symbolize Chicago’s industrial past and continue to serve as a testament to early 20th-century engineering innovation.
Additionally, the event demonstrates the ongoing public interest in these structures, which are both functional and visually captivating. It emphasizes the importance of maintaining and understanding critical infrastructure, especially as some bridges face aging challenges and potential upgrades.

Background
Chicago’s movable bridges have been a key part of the city’s transportation network since the early 1900s, designed to accommodate both road and water traffic. The 2014 exploration follows a long history of these bridges, which are celebrated for their mechanical complexity and aesthetic appeal. Prior incidents, such as the 1992 accident involving the Michigan Avenue Bridge, highlight the importance of ongoing maintenance and operational safety.
This event also coincides with broader discussions about infrastructure preservation in aging cities, emphasizing the need to balance historical integrity with modern safety standards.
“Seeing these bridges in action was a humbling experience, a mechanical ballet that has persisted for over a century.”
— Marcin Wichary
“It’s like conducting a symphony—each movement precise and deliberate.”
