What was the Speed of the Highway 401 (MacDonald Cartier Highway2) in the 60's?

I will need a website source to prove this one, I haven't been able to find it anywhere, The highway is located in Canada and is over 800km long. I learned all kinds of neat stuff about it but not what the speed limit was in the 60's.





Fustrated!!|||50mph (78kmh)

During the entire construction, two lanes of the freeway were kept open at all times with a posted speed limit of 50 mph (78 km/h), not an easy feat with all that construction! By 1967, the new configuration of Hwy 401 was complete from Hwy 400 on the west to Yonge St on the east. In the following years, the collector-distributor system was applied to all of the 401 from the Hwy 403 %26amp; Hwy 410 interchange in Mississauga on the west to Meadowvale Ave in Scarborough in the east. In some places today, the freeway is a staggering 18-lanes wide! In the early 1990s, this configuration was extended eastward along the 401 well into Pickering with further eastward expansion in the planning stages.


Today the stretch of Highway 401 that passes through the Greater Toronto Area ranges from 6 to 22 lanes.other than that it has no limit.
