Eternal Green Lights

I'm positive I replied to a similar and more recent thread with the same topic.

Southbound Percy Machin Drive in North Little Rock has eternal green arrows at the I-40 eastbound entrance ramp. There is no right movement as there is a railroad track on the other side.

Quote from: Scott5114 on December 06, 2024, 08:15:38 AMEastbound Cheyenne Avenue on the west side of Las Vegas has a number of consecutive three-way intersections, due to the "Great Wall of Summerlin" to the south blocking any through traffic. As a result, at each intersection, the rightmost eastbound lane is separated off as a bypass lane that always gets a green light. So if you're passing through the area and not turning, you never have to stop.

Here's an example where the Google car was actually using the bypass lane. (If you're not in the bypass lane, you can't see the green signal because it's a McCain PV signal that has everything but the bypass lanes masked off.)

So... there's just no way for pedestrians to cross through that entire 2.5-mile stretch without running across 6 lanes of traffic? I get that there aren't really any destinations on the south side of the street, but that still seems like a bad idea. And it's pointless since there are already traffic signals that could easily incorporate an actuated pedestrian phase.

Not only is there nothing on the south side of Cheyenne (not "not really any destinations" but "zero destinations"), but I'm guessing they don't really want people on the south side of the street at all. The only thing there is a drainage canal, which they want to keep people out of. What exactly would be the argument for making it easier to cross? So people could admire the masonry of Summerlin's wall?

I'm not sure why they even bothered building a sidewalk on the south side of Cheyenne at all, to be honest.

(As an aside, I've spent a decent amount of time in this area and it's sort of weird to me how little of it is zoned non-residential. There's basically nothing to do in the area unless you live there.)

But unique here is a pedestrian crossing across Lake Mead—so it's possible that the separated through lane signals are not "eternal greens" since they may actually turn red for peds to cross (although I've never seen that happen).

The sign for Lake Mead Blvd. at that intersection is sort of strange because it looks like its face once said "Lake Mead Blvd" but the "Blvd" part was cut off to fit a smaller sign frame. Possibly reused from elsewhere?

That shopping center was in the news recently because the day before your post, someone hacked their video sign to display a rainbow flag and the words "Gay furry pride, bitch". Never a dull moment in Vegas.

NB Oxnard Blvd at Robert Ave, Glenwood Dr, and Citrus Grove Lane in Oxnard, CA have eternal green lights

EB Ventura Blvd at the SB 101 on-ramp in Woodland Hills, CA also has an eternal green.

Before CA 71 was upgraded to a freeway, it had a couple of them (SB at 2nd Street in Pomona, NB at Old Pomona Rd)

I checked into local bus service out of curiosity. RTC route 218 services this stretch of Cheyenne up to Hualapai, but it's westbound only from Rampart/Durango to Hualapai as part of the turnaround loop (that's about a 1.5-2 miles for the turnaround loop). So not even a need to cross the street for transit.

Literally no reason for the sidewalk to exist on the south side.

I caught that on the VegasIssues Instagram. Hilarious!
