Eleven of those are in the South Side 19th Ward, the local alderman said.
CPS said 15 out of 30 intersections were affected.
Alderman Matt O'Shea says he was blindsided by cuts he calls drastic and unsafe in his ward's school communities.
"That's unconscionable, to go more than three days now without an explanation," O'Shea said.
Alderman O'Shea says there's been no communication from CPS to elected officials, school leadership, or parents, for that matter, whose children this affects, less than three weeks before the start of the school year.
The alderman says he reached out to the district three days ago, and still hasn't heard back.

Alderman O'Shea said, unfortunately, the district can do this without input or feedback from the public.
"The Chicago Public Schools has made a decision that their children can now try to traverse their way to school every morning and not cross Pulaski Road or 103rd Street or Western Avenue, where you have four lanes of speeding traffic. This is unbelievable; there needs to be an investigation, and CPS needs to be held accountable. And we need to be bringing people before the City Council to talk about this," O'Shea said.
The alderman has asked the Inspector General for Chicago Public Schools to launch an investigation, and for City Council to also call hearings on the matter.
The cuts come as CPS must close a huge deficit this summer.
CPS said in a statement:
"Chicago Public Schools (CPS) remains steadfast in its commitment to protecting classroom instruction and putting students first- even as the District confronts a $734 million budget deficit heading into Fiscal Year 2026.
"To minimize the impact on schools and students, CPS has taken a disciplined, student-centered approach to reduce spending. So far, the District has identified more than $165 million in savings through targeted central office cuts, including reductions to vendor contracts, operational spending, and administrative staffing-both filled and vacant positions.
"These are difficult but necessary decisions. No cut to public education is ever made lightly. Every dollar we save centrally helps protect students, teachers, and classrooms from deeper disruption.
"As part of these reductions, CPS eliminated about 100 of the District's more than 700 (732) crossing guard positions on June 27, following a comprehensive review of Chicago Department of Transportation (CDOT) safety data. It's important to note that no CPS school has lost its crossing guard program."
