<P> Much of the film was shot on location in and around Chicago between July and October 1979, including Wauconda, Illinois, where the car crashes into the side of Route 12 . Made with the cooperation of Mayor Jane M. Byrne, it is credited for putting Chicago on the map as a venue for filmmaking . Nearly 200 movies have been filmed in Chicago . "Chicago is one of the stars of the movie . We wrote it as a tribute," Dan Aykroyd told the Chicago Sun - Times in an article written to mark the film's 25th - anniversary DVD release . </P> <P> The first traffic stop was in Park Ridge, Illinois . The shopping mall car chase was filmed in the real, albeit shuttered, Dixie Square Mall, in Harvey, Illinois . The bridge jump was filmed on an actual drawbridge, the 95th Street bridge over the Calumet River, on the southeast side of Chicago . The main entrance to Wrigley Field (and its sign reading "Save lives . Drive safely, prevent fires .") makes a brief appearance when the "Illinois Nazis" visit it after Elwood falsely registers the ballpark's location, 1060 West Addison, as his home address on his driver's license . (Elwood's Illinois driver's license number is an almost - valid encoded number, with Dan Aykroyd's own birth date embedded .) Jake's final confrontation with his girlfriend was filmed in a replica of a section of the abandoned Chicago freight tunnel system . The other chase scenes included lower Wacker Drive, Lake Street, and Richard J. Daley Center . </P> <P> In the final car chase scene, the production actually dropped a Ford Pinto, representing the one driven by the "Illinois Nazis", from a helicopter at an altitude of about 1,200 feet--and had to gain a Special Airworthiness Certificate from the Federal Aviation Administration to do it . The FAA was concerned that the car could prove too aerodynamic in a high - altitude drop, and pose a threat to nearby buildings . The shot leading up to the car drop, where the "Illinois Nazis" drive off a freeway ramp, was shot in Milwaukee, Wisconsin, near the Hoan Bridge on Interstate 794 . The Lake Freeway (North) was a planned but not completed six - lane freeway, and I - 794 contained an unfinished ramp off which the Nazis drove . Several Milwaukee skyscrapers are visible in the background as the Bluesmobile flips over, notably the U.S. Bank Center . </P> <P> The Palace Hotel Ballroom, where the band performs its climactic concert, was at the time of filming a country club, but later became the South Shore Cultural Center, named after the Chicago neighborhood where it is located . The interior concert scenes were filmed in the Hollywood Palladium . </P>
