Zone

Haul roads

Crews and equipment will enter and exit work zones, transporting material to and from the site. Flaggers will be on site to assist with traffic flow around the work zones as needed. There will be dust while the work activity is being performed, and the contractor will implement the necessary procedures to mitigate the dust. View the haul roads map to see where transportation of materials will occur. 

Noise monitoring

The contractor is installing monitors to measure pre-construction noise levels, followed by noise monitoring post-construction to ensure construction noise isn’t excessive.

The short and long-term monitors will be placed in locations south of 95th Street along the Dan Ryan to Eggleston Avenue; and then along the Union Pacific Railroad freight tracks south of the Dan Ryan Expressway to the area south of 130th Street and Cottage Grove Avenue.

Advance utility relocation

CTA since 2024 has been relocating utility equipment to clear the way for new track and station construction to avoid delays in the project when major construction is under way. The work has included:

  • New underground trenches and relocating power and communication lines
  • Shorter poles will be installed to provide service to adjacent properties
  • Relocating power transformers on poles to underground

The area of this work is located across the project area from 95th Street to south of 130th Street.

Security

Safety and security for the community is a top priority, including proactively ensuring that properties that are awaiting demolition are secured and do not become nuisances for neighbors.

To do this, we work closely with a property management company, East Lake Management, that secures and regularly monitors and inspects all CTA-owned properties, addressing any issues that arise and swiftly responding to any questions or concerns raised by community members.

East Lake secures properties by conducting comprehensive site surveys, removing debris, boarding up windows, changing locks, mowing and weed removal graffiti removal, and snow removal. Any issues spotted or reported will be immediately addressed. Any criminal activity that is suspected or observed is immediately reported to Chicago Police.

While we make consistent efforts to be a good neighbor and steward of CTA properties, we strongly encourage neighbors to if they see something, say something by calling East Lake Management at (312) 842-5500. Any illegal or nuisance activity is unacceptable to CTA and we strongly recommend neighbors to call 911 if they believe they are in danger or witness what they believe to be criminal activity.

REDefine Southside Partners Joint Venture (RSPJV), the CTA’s construction manager for the Red Line Extension Project, will also install video cameras to monitor and document work activity on the RLE construction site. The sole purpose of the cameras will be to monitor and document work activity on the RLE construction site.

Construction activity notices (CANs)

As we work hard to build the Red Line Extension, we know that our construction can and does affect people who live and work nearby. This is why we provide advanced notice to communities in the RLE project footprint about work that we will be doing. These Construction Activity Notices (CANs) are also emailed to affected residents and businesses and physically posted in work site areas.
