CHICAGO (CBS) — The CTA Yellow Line between Skokie and the Rogers Park neighborhood will be out of service for a few days, after an embankment was washed out due to a construction accident, the CTA said.
CTA spokeswoman Tammy Chase said the soil under the McCormick Boulevard viaduct – between Howard and Oakton streets – eroded and collapsed Sunday night, due to a construction project not controlled by the CTA.
The Metropolitan Water Reclamation District of Greater Chicago was working on a disinfection project at the nearby O’Brien Water Reclamation Plant, when an “open cut retention system conduit was compromised,” according to MWRD spokeswoman Allison Fore.
“The District is working with its contractor and CTA to resolve any issues as soon as possible. We apologize for any inconvenience this incident has caused,” Fore said.
The MWRD accident caused a washout of the ground under the Yellow Line tracks at the McCormick Boulevard viaduct, and the Yellow Line was shut down as a precaution.
“Soil erosion and what looks like a partial ground collapse has made the track unstable and unsafe,” Chase said.
