Here is a concept route for an 'Enhanced Bus' line to connect Sandy with the South Jordan and Draper FrontRunner Stations, as well as the Prison site and the future TRAX stop by Highland Drive (if/when the east alignment is picked).
I tried not to use
any dedicated bus lanes and instead relied upon secondary roads as much as I could. Station stops would be on the sides of the street but would include platforms and would allow the buses to stop very briefly in traffic. Example from UVX:
We start at the Convention Center, in the north east corner of the parking lot by the existing TRAX station. This section of the parking lot can be turned into a sort of transit center with a bus turn-around and a staging area for the whole route. The bus then uses Town Ridge Parkway to get to Monroe Street, which it follows through 'downtown' Sandy.
I couldn't find any good way to get across the freeway/railroad tracks, so I decided that 10200 South was a perfect location for a new bridge. The buses would 'corkscrew under then over the bridge so as to get close to the mall for a convenient station location. Once across the bridge, the buses would head south down Jordan Gateway (Street), passing the FrontRunner Station and continuing south until 12300 South.
At 12300 South the buses would go east/west along 123rd through two lights. I know this street is busy but it isn't a long enough stretch for bus lanes, and there is no room beneath the railroad bridge. I think that bus-specific signals that allow the buses to proceed before the rest of the traffic would be just as effective as separated bus lanes.
After passing the Draper FrontRunner station the route goes through the prison site and up the steep hill to the future Highland Drive TRAX station:
In total, this route would be ~10 miles long. Without the need to rebuild any of the streets to fit separated bus lanes, the only construction would be the new stations and the new bridge over I-15. Compared to running TRAX through the same corridor it would be an absolute bargain!
Bus stations can be shorter and so wouldn't disrupt the area around them nearly as much as a TRAX station. Buses like the UVX line can run even more frequently than a rail line can, and so can be even more convenient. And if electric buses are used, this route will have no more impact on the air quality and environment than a TRAX line.
I say build the East TRAX line, because alternative bus routes like this can be done!
