Intentional bump of this topic to make note of a few things.
I’m in Vegas right now for work, and I see that there has been a repaving project going on along Summerlin Pkwy between 215 and Rampart or Durango, which is in the finishing stages. Nothing major to report in the way of changes to road configuration and such, but I can address a couple things mentioned upthread.
Also, is there a reason why there are no freeway entrance signs at on-ramps to Summerlin Pkwy? It seems like it meets the requirements of a freeway at all points except the interchange with CC 215.
I've always wondered this myself. Summerlin Pkwy is the only freeway facility in Nevada lacking such signs. My only guess is that there's not a route shield for Summerlin Pkwy (but they could have put the road name on a sign to make such an assembly work).
Conversely, I do not expect SR 613 signs to be posted at all. 500/600 series routes along arterial roads in the Las Vegas Valley are scarcely signed. Summerlin Pkwy has existed for nearly 30 years without a number, so adding SR 613 signs is not really going to benefit anyone.
You're probably right about that since Summerlin Parkway is all anyone has ever known that freeway to be, but it still would be to see some route markers along its course, especially since some mapping applications (like Google and OpenStreetMap) are placing it on their products.
I think I’ve reported elsewhere on the forum that the BGSs along CC 215 had SR 613 shields added atop them a few years ago, but that has been the only field signage of the route number.
The current project is in final stages such that much of the permanent signage has been installed. I can report that SR 613 shields are now more prevalent on and around Summerlin Pkwy. Reassurance shields are now in place along the freeway in the project area after each freeway on ramp. Additionally, “freeway entrance” sign packages, including shields, appear to have been installed along the side streets. Also, some of the overhead BGSs on side streets have been replaced with versions that include a 613 shield.
Another thing to report is BGS signage along Summerlin Pkwy as well. Originally, most of the signage was post mounted along the side of the roadway—now, most signs are relocated overhead (and unlit, as keeping with more recent NDOT practice). Additionally, NDOT has added exit numbers to these western interchanges: Rampart Blvd (exit 3), Town Center Dr (exit 1), Anasazi Dr (exit 0)*, and the 215 does not have an exit number.
I did not see mileposts, but that tends to be one of the last things installed (often by NDOT crews and not the contractors).
* Note that this is the first instance of an ‘Exit 0’ in Nevada, despite that fact that two other interchanges should be marked as exit 0—the I-15 Primm interchange (right at the CA state line) and I-215 interchange with I-11/I-515/US 93/US 95.
