I am not sure if this has ever been seen or discussed here:

This is about a Study that was done by UDoT a few years ago and it has some feedback on 3 scenarios from local leaders, UTA, and some from the State.
Based on some current plans from UDoT and the State Legislature, they have opted to go forward with a modified version of Scenario 3.
To my knowledge, they have dropped the Elevated I-15 segment as the public outcry was too much.
Key transit points though are:
Doubletrack/electrify FrontRunner commuter rail
Add infill rail transit stations (Bluffdale was removed once the Prison relocation was a done deal. The Trax Lines through the area were added however. Centerville is still an option.)
New arterial HOV and BRT lanes with grade ‐ separated intersections I am not sure about widening Redwood and State Street in places but the grade separated HOV and BRT lanes at 4500 South, 5400 South, 7000 South, 9000 South, and 10600 South do sound interesting.
"Cycle super highway" network
Buffered bike lanes/cycle tracks on selected arterials
Mobility Hubs Proposed mobility hub locations for WFCCS are downtown intermodal, Murray Central FrontRunner/TRAX station, and proposed infill station in Bluffdale (now prison redevelopment site in Draper).
Lastly are the items that are constant on all 3 scenarios:
Increased transit frequency during peak period Increase frequency of TRAX, FrontRunner, and/or buses in corridor. - The goal here is to cut the wait times in 1/2 if possible (15 to 7.5, 10 to 5, and so forth for all transit forms).
Transit pricing Analyze as free fares. - Even then, they were looking at Free Fares.
Overall, it does look like UDoT and UTA have been coordinating their approach towards the overall 2050 goals for a few years now and the Legislation this year will help align it faster with the State backing transit projects while also making driving more costly (raising the gas tax).
