Construction activity notices (CANs)

As we work hard to modernize the system for our riders, 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 RPM 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.
