The High Road Bridge is a road bridge over Long Run Creek in Lockport Township, Illinois. It is the world's first road bridge built using the hybrid composite beams (also known as Hillman-Composite Beam) (HCB's) invented by John R. Hillman and developed by the HC Bridge Company LLC. The HCB's are stronger, lighter and more corrosion resistant than the traditional concrete or steel beams. The HCB beam with a life span of 80 to 100 years and with minimal or no maintenance to the bridge girders is a cost competitive alternative to steel and concrete beam. It was designed by Teng & Associates and constructed by Herlihy Mid-Continent Company in 2008. The 17.4 m (57 ft) long, single-span bridge consists of six HCBs supporting a conventional 20 cm (8 in) thick reinforced concrete deck.

Old Chicago was a combination shopping mall and indoor amusement park that existed in the southwest Chicago suburb of Bolingbrook, Illinois from 1975 until 1980. It was billed as "The world's first indoor amusement park", and it was intended to draw visitors all year round, rain or shine. It opened to great fanfare and over 15,000 visitors on June 17, 1975, with an enormous building that housed major rides, such as three roller coasters and a Ferris wheel, as well as a turn-of-the-century-themed shopping mall with design reminiscent of the architecture of Louis Sullivan, such as his work for the 1893 World's Columbian Exposition in Chicago. However, only six months after opening, the complex ran into financial troubles due to construction cost overruns. The opening of a competing amusement park in Chicago's north suburbs (known today as Six Flags Great America) hurt attendance, and the lack of large anchor stores failed to draw enough local and repeat shoppers. Despite management changes, the center continued to lose money. By 1978, the mall began closing on Mondays and Tuesdays, and in early 1980 the entire amusement park shut down and the rides were sold, only five years after opening. Efforts to find alternative uses for the huge building failed, and the structure was demolished in the spring of 1986. Its address was 555 S. Bolingbrook Drive, Bolingbrook, Illinois 60439.
