shows a partial southeastern beltway, connecting SR-154 to Highland Drive and 9400 South (SR-209). It's been removed from the current version, but still appears on . Google maps, aerials, and street view show what appears to be a cleared right-of way through Sandy but no construction, and several disjoint sections of Highland Drive.  shows a proposed bike path there. There appears to be nothing in the corridor shown to connect Highland and SR-154, but the Bangerter Parkway has opened recently (apparently to serve the subdivisions on Traverse Ridge Road).
 also shows a partial second southwestern beltway, extending 5600 West to the curve in SR-154. Could Rosecrest Road be part of this?  shows that it has been realigned to enter Utah County (probably as part of the Mountain View Corridor), but the exact alignment shown is no longer possible.
Does anyone know the history of either of these? I found a bit about Highland Drive; has the land been sitting unused since the 1990s? --NE2 10:47, 1 July 2008 (UTC)
- All I can add is speculation. Those articles about Draper homeowners getting angry are from the mid- to late-1990s, right before I-15 was reconstructed. Perhaps the southeast extension was planned to be constructed as a part of the reconstruction, but this is just judging by the time period. As for the southwest extension of 56th West, I haven't heard anything on it. I remember reading somewhere that Bangerter was going to be upgraded to freeway status from I-15 to 13400 South (West Jordan said they were the largest city in the state without freeway access), but I'm not sure what the deal is with this either. A quick search of UDOT projects present and future here shows nothing. CL — 17:51, 1 July 2008 (UTC)
- Hmmm. The 2007-2030 regional transportation plan (May 2007) lists the gap in Highland Drive as four lanes on a six-lane right-of-way, to be constructed "between 2016 and 2025". There's nothing on SR-154 except making the east-west segment a freeway (also between 2016 and 2025), but don't forget the Mountain View Corridor (which would have a spur to SR-154 at 13400 South). --NE2 19:05, 1 July 2008 (UTC)
