Metrolinx GO Expansion Program - Reconstruction of Birchmount Road Bridge - Temporary Road Closures and Transportation Impacts

The reconstruction of the Birchmount Road bridge is required to accommodate expanded rail infrastructure while maintaining long-term roadway connectivity serving surrounding residential neighbourhoods and employment areas. The report seeks City Council approval for the long-term temporary lane closures and associated temporary traffic by-law amendments required to accommodate construction staging, maintain public safety, and support the delivery of this critical infrastructure project. The report also identifies mitigation measures to manage transportation impacts and maintain safe and reliable access for pedestrians, cyclists, transit users, motorists, emergency services, and local businesses throughout the construction period.
