Wacker Drive is getting a $366 million facelift.
Beginning in April and slated to last three years, the project includes work on the artery's upper and lower levels from Randolph to Congress Parkway. A separate service drive will also be created on the lower level with increased space and better lighting.
The governor's office says the work will include increasing clearance on the street's lower segments and replacing entrance and exit ramps.
The announcement comes less than a week before the state's primary election. Also Wednesday, Quinn announced an $8 million project to renovate the site of Northern Illinois University's campus shooting two years ago.
