The Vancouver stretch of Highway 1 (Grandview to McGill) could *easily* be 90 km/hr.
When you consider how much safer cars are now compared to 20 years ago, and all of the improvements to the highway (widening, larger shoulders, merge length, sightlines), it's clear politics rather than engineers are driving the speed limits.
I don't buy the argument that the tunnel necessitates a lower limit, it's straight as an arrow and relatively short and will have dedicated add/drop lanes (compare that to the 91/91a interchange which is a hairpin curve with weaving entering and exiting traffic and still manages to operate at 90 km/hr).
I have a sneaking suspicion the limit is staying at 80 because of concerns about noise, rather than safety.
