The Chicago Department of Streets and Sanitation says the next phase will start on Monday. The program started with about 55,000 homes on the North Side last month.
The new system aims to be more efficient, make crews more productive and save taxpayers money in operation costs. Streets and Sanitation Commissioner Thomas Byrne says residents may have their garbage picked up on a different day but service will still be weekly. Last week crews posted "Change in Garbage Service Day" notifications in affected areas.
Chicago Mayor Rahm Emanuel says the new system shows the city is "choosing efficiency over politics to protect taxpayer resources."
Households in wards 33, 38, 39, 41 and 45, as well as small portions of wards 30, 35 and 40 are affected.
