Adjacent Construction (placeholder)

Construction Near Us

If you're performing construction near where our trains operate or which might affect bus services or riders' access to our services, you'll need to work with one or more groups at CTA before we, our service or our customers are impacted.

Construction near 'L' train rights-of-way

If you're performing construction above, on, below, or adjacent to CTA's rights-of-way (where our trains run), you're required to attain appropriate flagging, inspection, and/or rail safety training to ensure that your project will be conducted in a manner which does not present a hazard to our infrastructure, the public, the operation of transit vehicles, or a hazard to you or your workers.

Before starting work, you'll need to meet with a CTA representative to determine requirements for flagmen and other tradesmen, if required, and any other necessary items related to the work activities next to our facilities, in order to receive approval for your proposed work activity.

Getting details

For complete details on how to get the necessary authorizations for working along our right-of-way, including more details on requirements, fees and how to apply, see our  Right of Way Requirements document (.pdf).

Regarding technical requirements working around our right-of-way, also see: Adjacent Construction Manual (.pdf)


Construction near/affecting streets used by our buses

If you’re performing construction in the public right-of-way where CTA buses operate in the City of Chicago or surrounding areas, CTA must be notified. CTA requires at least two weeks' notice of the following in order to coordinate bus service adjustments and provide notice to bus operators and customers:

  • Pre-construction meetings
  • Phase changes and re-starts of existing projects
  • Bus reroute requests
  • Bus stops or shelters affected by construction
