--- Quote ---Work to replace striping in Utah County wrapping up soon; Salt Lake, Davis, Tooele and Summit to start in September

Utah Gov. Spencer Cox announced the next phase of the Utah Department of Transportation’s (UDOT) effort to upgrade freeway lane striping along the Wasatch Front with wider markings designed to last longer and be more visible to drivers.

The Enhanced Freeway Striping project is replacing lane markings on Wasatch Front freeways with new, wider lines designed for high visibility and reflectivity and using contrast striping, which includes a white line followed by a black line (known as a “tiger tail”  and helpful for autonomous vehicle sensors and cameras), for the lines in between lanes. Construction began on the Utah County segment of I-15 earlier this spring and is scheduled to be complete by early fall. Another phase in Salt Lake, Davis, Tooele and Summit counties is scheduled to start in September, and will include sections of I-15, I-215, I-80 and SR-201.

For years, Utah has been using simple white lines on asphalt highways and white lines with small black borders on concrete highways, which are really hard to see when it rains. I've seen the new "tiger tail" striping on some of I-15 through central Salt Lake County, where a new lane was just added, and am really excited to see it expanded. Contrary to what some of the instagram commenters state, in my experience it does in fact make a difference.

I wish Nevada DOT would go this route with the lane lines on cement freeways here in northwestern Nevada. Several years ago, they did the 'white paint stripe with thin black paint stripe borders' as an experiment–it was helpful, but I think they really only painted that down once or twice and haven't refreshed the black in a few years. There's a lot of areas where the paint hasn't been refreshed this year and lane lines are worn if not gone. Slightly recessed thermoplastic like this would seem like it has a lot of long-term benefits.

While the strips may deteriorate and eventually need replacement, at least they don't fade like chalked lane markings can. Of course, if the roads are covered in ice and snow, neither chalk nor strips are much of an advantage.

I'm assuming you mean "taped" lane markings versus "painted" lane markings. Nobody is out there using chalk for lane lines, which would wash away the first time it rains...

US 89:
Looks like UDOT is in the early stages of an environmental study for general transportation in the northern Lehi/Thanksgiving Point area. It looks like a lot of things are being considered here, but most interesting is a potential extension of SR 92 west over the Jordan River:

It's early in the process, so there aren't any alignments or even endpoints proposed. Given that such an extension would probably have to pass directly through the Thanksgiving Point golf course, as well as the large areas of federal and military bases west of the river in that area, I personally would be shocked if this were to ever actually happen. Also, this is the first I've heard of this "Planned POM Connector" that's on the map.

Looking at the Unified Transportation Plan, it looks like this 92 extension is supposed to connect to the point where 3600 West and the planned POM Connector meet next to the Jordan River. That Connector is supposed to extend to an intersection with Porter Rockwell Blvd in Salt Lake County, with a connection east to I-15 about halfway between the county line and SR 92.
