While this is sorely needed, I wish UDOT also added recessed pavement reflectors. Parts of California and Arizona use them and it makes it so much easier to see where the lanes are at night.
Does Utah get much snow? Recessed reflectors could be covered up in a snowstorm
Yes. Except for back like 10 years ago it fell frequently a couple inches at a time throughout winter. Now (*cough* global warming *cough*) falling much less frequently but at really extreme heights, so IDK if reflectors still would work in UT...are there any other places in the Mountain West similar to UT with reflectors? Because I don't think Colorado's considered them either, and while Las Vegas has them, I don't recall Reno or Carson City having them at all.
Raised pavement markings are not common in Nevada outside NDOT District 1 (southern Nevada), and except for a couple one-offs at some rural spot applications, are not really seen anywhere north of the Las Vegas urban limits.
I know of one location in Reno, Nevada that had recessed reflectors in the pavement: The I-80/Keystone Avenue interchange. Recessed reflectors were used in conjunction with painted lines to guide left turns through the SPUI. My hunch is that these were used for extra guidance given this is only second SPUI constructed in northern Nevada, and only used because the SPUI intersection is below the freeway (so the reflectors wouldn't be covered by snow). The intersection was repaved as part of the recent I-80 Reno West project, and the recessed reflectors no longer exist.
