On October 20, 1926, Chicago Mayor William Emmett Dever officially opened Wacker Drive, describing it as “the greatest improvement of its kind in the world’s history.” The newly constructed double-deck roadway transformed eight blocks along the south bank of the Chicago River, replacing a congested area of poultry stalls, vegetable vendors, and dilapidated buildings with a Beaux Arts boulevard. This newly opened section linked directly to the two-level Michigan Avenue Bridge completed six years earlier, offering a modern thoroughfare that significantly improved traffic flow in downtown Chicago.

Wacker Drive was named after Charles H. Wacker, a prominent figure in Chicago’s beer industry and longtime chairman of the Chicago Plan Commission. The commission had been formed 17 years earlier to advance the vision articulated in the 1909 “Plan of Chicago,” authored by Daniel H. Burnham and Edward H. Bennett. The plan called for beautifying and modernizing the city, including creating elevated boulevards along the Chicago River modeled after the Seine in Paris. Wacker was instrumental in advocating for these improvements and detailed his support in “Wacker’s Manual of the Plan of Chicago,” which became educational material for local students.

The opening of Wacker Drive was the culmination of years of planning and controversy. The area, formerly known as South Water Street, had been a bustling commercial district since the 1830s but had become increasingly congested and unsightly by the early 20th century. Efforts to clear the area faced legal challenges, tenant protests, and disputes over property compensation. When demolition began in 1924, city officials faced resistance from merchants reluctant to relocate. Despite opposition, the project proceeded after voters approved $28.6 million in bonds in 1919, with $3.8 million allocated to this specific development.

The original stretch of Wacker Drive, which extended from Michigan Avenue west to Lake Street, cost $24 million (approximately $457 million in today’s dollars). Its construction was a major engineering feat, involving excavation down to bedrock 118 feet below the surface and extensive use of structural concrete. The roadway’s upper level featured broad traffic lanes and promenades overlooking the river, while the lower level accommodated six lanes of traffic and loading docks, with additional basement parking between Michigan and Wabash avenues.

Although praised for significantly improving urban infrastructure and riverfront aesthetics, some historians note that Wacker Drive fell short of Burnham’s grand vision. Only the south bank received a double-deck design, and the comprehensive network of riverfront boulevards extending far north and south was never realized. Despite this, Wacker Drive underwent expansions in later decades, including a southern extension completed in 1958 connecting to the Eisenhower Expressway and an eastern extension in the 1970s reaching Lake Shore Drive.

By the early 21st century, Wacker Drive had become an iconic element of Chicago’s transportation network and cultural landscape, featured in films such as “The Blues Brothers” and “The Dark Knight.” Efforts to revitalize the adjacent riverfront began under Mayor Richard M. Daley in the 1990s, with subsequent development of the Chicago Riverwalk under Rahm Emanuel transforming the once-neglected area into a prominent public space. The Riverwalk’s success continues to reflect the enduring influence of Burnham and Bennett’s original vision for a more connected and scenic Chicago.
