The Mississauga Transitway consists of busways and bus-priority lanes. The first segment of busway parallels Highway 403 from the western terminus at Winston Churchill Boulevard to Erin Mills Parkway. From there, buses use dedicated shoulder lanes on Highway 403 and Centre View Drive to reach MiWay's existing City Centre Transit Terminal on Rathburn Road. The longer second busway begins east of Hurontario Street, paralleling Highway 403 to Cawthra Road and then following Eastgate Parkway on its north and west side to Eglinton Avenue East, and Eglinton on its north side to the eastern terminus at Renforth Drive in Toronto.
