--- 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.

Sixty years ago, in September 1963, the Flaming Gorge Dam was completed, which later enabled the routing of Utah Highway 260 over the dam and the early 1980s-extension of U.S. Highway 191 over the dam and the nearby Cart Creek Bridge.

--- Quote ---President John F. Kennedy made a profound statement Sept. 27, 1963, when he pressed a switch that opened the penstocks at Flaming Gorge Dam and started a system that has produced hydroelectric power for six decades. “The important thing to remember is for 50 years men have been talking about this project,” Kennedy said. “It is now a reality. What are we going to do now so that 50 years from now the people who live in Utah and the United States will feel that in the early ’60s we made the proper decision for the management of our resources?” ...

But the presidential connection with Flaming Gorge goes back to 1956, when President Dwight D. Eisenhower made a telephone call to a man overlooking the dam site. On the president’s command the man fired a rifle that signaled workers at the dam site to set off the first explosion that began construction on the dam. A photo of President Eisenhower smiling with his Secretary of the Interior Fred A. Seaton as they trigger the explosion are part of the exhibit. President Eisenhower also initiated construction of the Glen Canyon Dam on the Colorado River in northern Arizona that same day. Glen Canyon Dam construction was completed in 1966.

Kennedy was assassinated in Dallas, Texas, on Nov. 22, 1963, about two months after he initiated power production at Flaming Gorge. Lady Bird Johnson, wife of Kennedy’s successor, President Lyndon B. Johnson, dedicated the visitor center at Flaming Gorge Dam on Aug. 17, 1964.
