The Richview Expressway was only partially completed due to concerns of under-utilization and opposition from local residents. Even though Richview Expressway was never built, it did result in widening of a section of Eglinton Avenue from Black Creek Drive to Highway 427.
The Richview Expressway has also been known as the Hamilton Expressway, since the original routing for Highway 403 (a main route for Torontonians to travel to Hamilton) was planned to terminate at the present site of the interchange between Highway 401 and Highway 427. If the original routing of Highway 403 had been carried out, then Metro's Richview Expressway would have been considered a municipal extension of Highway 403.
