bascule trunnion bridges. The bridge at Adams Street and its neighbor at Jackson Boulevard are the only two single deck bridges in the city that represent the Plan of Chicago's ideal" downtown river bridge. The Jackson and Adams bridges are also among the oldest spans still in use along Route 66 and two of the busiest in Chicago—therefore probably in the state—due to their heavy volume of weekday pedestrian and commuter traffic crossing the bridges to and from nearby Union Station. Museums and attractions Illinois is home of various museums devoted to the history of US 66, such as the Berwyn Route 66 Museum in Berwyn, the Joliet Area Historical Museum's Route 66 Welcome Center, the Illinois Route 66 Association Hall of Fame and Museum in Pontiac, and the Cruisin' with Lincoln Visitors Center, inside the McLean County Museum of History in Bloomington, Illinois. Vehicles used by late Route 66 travelling artist Bob Waldmire, including a Volkswagen Type 2 minibus that inspired the creation of Pixar animated character Fillmore in the film Cars, are part of the museum collection in Pontiac. Two other museums of interest in Pontiac are the International Walldog Mural and Sign Art Museum and the Pontiac–Oakland Museum. The newest Route 66 museum is the Litchfield Museum and Route 66 Welcome Center, which opened in 2012 across from the Ariston Cafe. This museum houses an extensive history of the city of Litchfield and offers guided tours and special events. Route 66 in Illinois is also famous for some very quirky jumbo-size attractions, such as the former Bunyon's Paul Bunyan statue, a "Muffler Man" giant originally from a Berwyn hot dog shack that now stands in the quaint downstate community of Atlanta; the similar Gemini Giant in Wilmington; the largest wind farm East of the Mississippi River, Twin Groves Wind Farm, just east of Bloomington, with more than 240 turbines across ; the Railsplitter Covered Wagon in Lincoln, the world's largest according to Guinness Book of World Records; the Route 66 mural in Pontiac that depicts the world's largest US 66 shield; and the Tall Bunny at Henry's Ra66it Ranch in Staunton. There are a number of other attractions along Historic US 66 that are in the process of being restored, such as Sprague's Super Service gas station in Normal and The Mill on 66 restaurant in Lincoln. Both sites have received numerous grants and philanthropic donations, but
