Metro Toronto Roads and Traffic (later Metro Transportation) was a department within the former Municipality of Metropolitan Toronto.
The department was responsible for maintaining major arterial roads, bridges and local freeways systems (Gardiner Expressway, Don Valley Parkway and W.R. Allen Road) in Metropolitan Toronto and all traffic signal-controlled intersections. Metro roads were akin to county roads, but were not signposted with numbers.
The department did have influence over the design of the city. One example is the width of Yonge Street. When the Toronto Eaton Centre was built, it was setback from the street as to allow the possibility of a future lane of traffic[citation needed]. It wasn't until the late 1990s that the mall was allowed to expand out towards Yonge.
Metro Toronto Roads and Traffic bronze plaques are found on bridges throughout Toronto, but some are being replaced with City of Toronto signs as they are refurbished by Toronto Transportation.
