That might actually work. Now I wonder whether the non-existence of AB-89 is coincidental or intentional.

I think at this point, the availability of AB-89 is coincidental as most numbers are lower. AB-88 used to be AB-67, but was renumbered in 1988 and designed as the Bicentennial Hwy in honour of Fort Vermillion's bicentennial. Then there's AB-93...
I couple years back I emailed Alberta Transportation with that same idea. I was told that it was considered in 1990s when the North-South Trade Corridor was established (resulting AB 4/2/43 being upgraded) but was decided against because they have a policy against concurrencies and the impact on local residents in changing highway numbers. I can appreciate the impacts on local residents, but that hasn't prevented other renumbering projects in the past and would further solidify the N-S Corridor in Southern Alberta. As for concurrencies, I can appreciate wanting to avoid overkill on concurrencies, like what you might see in other jurisdictions, especially in the U.S. (US 87/US 89/MT 3/MT 200 east of Great Falls, MT comes to mind), but policies can also evolve over time as needs change. It's ~55 km from Hwy 2 north in Fort Macleod to 43 St/Hwy 4 South in Lethbridge, which doesn't seem like an overly long or redundant concurrency. The fact that a sign like this in Lethbridge is needed,
