Regarding Foothill, the width of the right of way south of Foothill Village makes any sort of rail line along there very difficult. The ROW varies from 100-110 feet. LRT requires a minimum of 28 feet horizontal right of way. that reduces the overall width down to 70-80 feet. If you put in 15 feet of sidewalk and park strip on each side, you are down to 40-50 feet. With a minimum lane width of 12 feet, at the wide parts (between FV and 1700 South) you could get 4 total lanes with no on street parking, no bike lanes, etc. At the narrow points, you would be 8 feet short. You could reduce the sidewalk/park strip width, or have the track line a single track at that point, but it is incredibly difficult to time the trains over that length. Not to mention that Foothill is a UDOT road, so I doubt they will be too into giving up ROW for a rail line.

For comparison purposes, 400 South is approx. 132 feet wide. South campus Dr through the U is only about 80 feet wide, but the sidewalk is integrated into the curb and most of it is outside of the official right of way. The travel lanes are also only 11 feet wide, but they can be that width with the reduced speed limit.
