So to go with this conversation here are the planned upgrades for highway 1 near chase.
Looks like the preferred options are to be grade separated (one protected T will be constructed west of these projects).
Here is the preferred option for the western portion of Chase. Grade separated:

Here is the runner-up option, also grade separated:

There will be another access point east of Chase for a few properties. It says that it is technically "at grade" but a closer looks shows that there are no movements across traffic (no break in the median divider).
So it looks like the interchanges are the preferred options, but it never hurts to help by sending in your comments to the BC ministry of Transportation supporting the grade separated interchanges for these projects.
2022 is the expected completion dates. So Kamloops to Chase will be 4 lanes the entire way when these are complete with primarily interchanges (as stated before).
