the previously common dirt roads. Public road planning in Chicago began in 1910 when the Chicago Plan Commission was created to implement Daniel Burnham and Edward Bennett's plan. The double-decked portion of Wabash Avenue north of the Chicago River was built in 1930, in conjunction with the single-level Wabash Avenue Bridge. On January 3, 2005, the upper and lower levels were closed at Kinzie Street for reconstruction (in conjunction with the Trump Tower Chicago development) but have since been reopened. The city's famed Billy Goat Tavern, immortalized by John Belushi in a Saturday Night Live sketch as the Olympia Cafe, is located on the lower level of Michigan Avenue.
