A 100-ton hydraulic drill rig toppled over on Chicago Transit Authority elevated tracks near the Bryn Mawr station on Chicago's North Side on Oct. 6 around 3:30 P.M., falling into an alley at street level. Disassembly and removal of the collapsed drill rig was underway on Oct. 7. The drill rig was being used as part of an ongoing CTA modernization project.
No injuries were reported, but power lanes were damaged and CTA service at the Bryn Mawr station was suspended for several hours. The CTA restored normal service the evening of Oct. 6 including stops at the Bryn Mawr station. An 18-unit residential building directly east of the station was evacuated and contractor Walsh-Fluor is paying for residents' stays in hotels until it's determined that it is safe to return.
