Let's talk about one-way streets

It'll definitely reduce wear and tear a lot, but most arterial roads need to get repaved every 10-15 years or so regardless. King St east of the RHVP to Centennial is in pretty rough condition despite not having a large amount of truck traffic already and it was last rebuilt in 2009, for example. It's currently scheduled to get repaved in 2026, so a 17-year service life. And honestly, it should probably have been more like a 12 year service life.

Local roads are what can last a lot longer, usually 30-40 years between resurfacings. Not having trucks helps, but a street like Main with the huge volumes of cars and buses which will still use it will still need regular work.

Plus removing them from downtown will increase wear and tear on other roads where they will be instead like Burlington St and the RHVP / LINC.

Honestly Hamilton gets screwed by having to maintain a good chunk of it's freeway network itself. It costs millions annually to maintain the RHVP and Linc, and in most other municipalities in Ontario those would be provincially maintained. Kitchener for example has it's entire freeway network provincially maintained, which saves an absolute ton of money for the municipality as a decent chunk of road mileage in the city is done on roads not maintained by the municipality. Hamilton is looking at some big bills to pay for widening the highways towards the end of the decade too, which would also normally be a provincial expense.
