| | Multilevel streets in Chicago - Wikipedia, the free encyclopedia |
 | | Downtown Chicago, Illinois, both north and south of the Chicago River, has some double-decked and even a few triple-decked streets, the most famous and longest of which is Wacker Drive. |
 | | The first raising occurred from 1855 to 1858, when streets and buildings were raised between four and seven feet above their former elevation, just a few feet above lake level, where they were constantly muddy. |
 | | On January 3, 2005, the upper and lower levels were closed at Kinzie Street for reconstruction (in conjunction with the Trump Tower Chicago development). |
