Franklin Delano Bridge: Chicago’s Historic Link Over the River

Spanning the Chicago River, the Franklin Delano Bridge, also known as the Outer Drive Bridge, stands as a testament to Chicago’s engineering prowess and urban planning vision. This double-deck bascule bridge not only facilitates the flow of traffic along Lake Shore Drive but also embodies the city’s commitment to functional design and aesthetic appeal. Since its inauguration in 1937, the bridge has played a pivotal role in connecting Chicago’s bustling downtown with its scenic lakefront, becoming an integral part of the city’s transportation network.​

A Monumental in Urban Development

The construction of the Franklin Delano Roosevelt Bridge was a significant milestone in Chicago’s urban development. Prior to its existence, traffic congestion plagued the city, particularly along Michigan Avenue. The bridge was envisioned as a solution to this problem, providing a direct route over the Chicago River and alleviating the bottleneck. Its completion marked a major achievement in the implementation of the Plan of Chicago, a comprehensive blueprint for the city’s growth and modernization.​

President Franklin D. Roosevelt presided over the bridge’s dedication on October 5, 1937, highlighting its national significance. The event was celebrated with much fanfare, including a ceremonial spray from the fireboat Fred Busse, named after the mayor at the time of the Plan of Chicago’s release in 1909. In the first half-hour following the opening, approximately 36,000 vehicles crossed the Franklin Delano Bridge, underscoring its immediate impact on the city’s transportation dynamics.

Engineering Marvel and Architectural Design

The Franklin Delano Bridge is a double-deck bascule bridge, a design chosen for its efficiency in accommodating both vehicular and maritime traffic. The bascule mechanism allows the bridge to lift, permitting ships to pass through—a crucial feature for a city with a bustling port. The upper deck was designed for automobile traffic, while the lower deck accommodated trucks and service vehicles, effectively segregating different types of traffic to improve flow and safety.​

Architecturally, the Franklin Delano Bridge was adorned with decorative elements that enhanced its visual appeal. Notably, the bridge featured obelisk-like light fixtures and classical posts topped with bronze sculptures. These sculptures, created by Hungarian-American artist Miklos Simon, included representations of dinosaurs, dolphins, and compasses, symbolizing the nearby Field Museum, Shedd Aquarium, and Adler Planetarium, respectively. These artistic touches reflected Chicago’s dedication to integrating art into public infrastructure.

Challenges and Subsequent Improvements

Despite its initial success, the Franklin Delano Bridge’s design presented challenges. The roadway’s sharp angles led to numerous traffic accidents shortly after its opening. This issue persisted until 1986, when the completion of a new S-curve corrected the hazardous turns, improving safety for motorists.

In 1994, a major rehabilitation project led to the removal of some decorative elements from the bridge. To preserve these artworks, they were relocated to Buttercup Park, where they continue to be appreciated by the public. This move exemplifies Chicago’s commitment to preserving its artistic heritage, even amidst urban development and change.

A Lasting Legacy in Chicago’s Infrastructure

Today, the Franklin Delano Bridge remains a vital artery in Chicago’s transportation network, seamlessly connecting the city’s north and south sides. Its blend of functional engineering and artistic design serves as a reminder of the city’s rich history and its ongoing pursuit of innovation. As both a practical thoroughfare and a historical landmark, the bridge embodies the spirit of Chicago—a city that values progress while honoring its past.​

Whether commuting across its spans or admiring its architectural details, those who encounter the Franklin Delano Roosevelt Bridge experience a piece of Chicago’s storied legacy, a structure that continues to stand as a symbol of the city’s resilience and ingenuity.
