DHS Parking lot remodel and expansion

I realize this is about DHS parking but looking at the photo, how would one get from Osceola Parkway westbound to Victory Way for Pop and AoA? The right-turn off ramp only leads to the new DHS entrance. Because presumably the throughfare will be an overpass over Victory Way.

When everything is done Osceola will pass over Victory and the areas I circled in red, which are the current travel lanes, will be come ramps with traffic lights at the end.

Specifically, here is a picture of the plans for turning left from Osceola westbound to Victory Lane southbound. This is from plans that @danlb_2000 posted in 2016. From Osceola westbound, there will be an exit on the right that splits into Ramp D1 going up to the DHS flyway and Ramp D2 going down under the DHS flyway for turns to Victory Lane northbound and southbound.

Interesting and as @FerretAfros has pointed out, the Osceola Parkway/Victory Lane part of the interchange is design called the single point urban interchange (SPUI), so it can be signaled using a three-phase traffic signal instead of the usual four-phase signal.

You can follow progress on the new interchange in the Osceola Interchange/Road Permits thread.

Sad to say, I am fascinated by modern intersection and interchange design. :)

Ever see one of these...

I've read about them but never actually driven through one. I wonder why it wasn't chosen here?

I am looking forward to the re-engineering of a lot of intersections with new science-based intersection and interchange design. Seems like just what we need to get us through the interim years until we're all floating around in driverless hoverchairs.

Side note, they actually opened one last year about a half hour away from me. MANY people complained about it during the planning and construction phase. But when it opened, traffic died down, and all of the sudden no one complained anymore. Same thing with a roundabout a couple years back.

It'll probably become more popular once people realize the benefits of it and stop being scared of a new idea.
Edit: Here's the video of the one by me. Very similar to @danlb_2000's video, but it features first person views which show how odd it looks.

Honestly? I think the best speculation is a lack of faith in the broad swath of potential drivers to use it effectively. If the DD was more mainstream (if this project was undertaken 20 years in the future) it would probably go in here.

I cross over one of these on my way to work everyday... same thing people complained it was too complicated a setup while they were building it... it was because of excessive accidents at this intersection, after it opened the amount of accidents drastically reduced. Basically it makes it so neither directions of traffic have to cross over the other to get acces to both directions on the highway it is crossing, pretty genius setup if you ask me.

We're getting on of these literally five minutes from my house and I'm quite excited. I keep trying to explain to people how it's remarkably easy to use, but they just see the cross-over and freeze. I can't wait until it's in regular use and they stop complaining.

Reading some of the reactions about them sums up how it ends up working out.
- "Yup, place near us used to regularly back up onto the highway, sometimes close to a quarter mile. They put one of these in, after a week or so everyone figured it out and it’s infinitely better."
- "Lexington Kentucky freaked the **** out when one of these guys was constructed a few years ago. Here it is called a Double Diamond Crossover, although at first we knew It as “the Double Diamond Crossover of Doom”. The overall attitude was that it was too complicated and would only make things worse. Turns out, it was a fantastic idea and has definitely helped traffic flow. Now if only we could get the hang of round-a-bouts."
- "They put one of these in by me and it completely changed the flow of traffic. It used to be a complete *********** of cars and poorly timed lights, with everybody racing through yellows and reds to try to get a little further ahead.
It was weird driving through it the first couple times but after that it was simple. Congestion has gone waaaaaaaaaaay down since then."
- "I live in St. Louis, MO and a few years ago they put one of these at a busy highway intersection. BEST. THING. EVER. What was once a giant ********** of congestion is now a stretch of road I don't have to avoid any more! "

Of course there's negative reactions such as "more lights=bad" but those usually don't realize the lights are shorter then normal red lights. It's better overall regardless of what people think of it.

people are creatures of habit and its difficult to change their paradigm of thinking. Sounds like a lot of people on these boards.... OMG what is disney doing this is different and its going to be awful... *Disney finishes project* oh, thats actually kind of cool *in a reluctant tone*

Roundabouts barely work out over here. I could see so many people dying of shear fear if they just heard they were building something like that in the US.

I do wish we had more roundabouts here. Such a good idea and super efficient. Until grandma stops in the middle of it and kills the flow.

Roundabouts (circles, rotaries) are great for light traffic (and if everyone knows that all roundabouts have the same rules, i.e., everyone entering must yield), but they lose efficiency in heavy traffic. Then they start backing up, not enough breaks in the circle for cars to get in, governments put extra layers of organization (more inner lanes, declaring certain roads have the right of ways, traffic lights to break up the jams) which make them too complicated.

Jersey used to have lots of 'circles', but most are gone now replaced by giant intersections governed by traffic lights. Also, we tend to ban left turns. Gotta go right to make a left.

True but in a good chunk of places, roundabouts would probably work out better. I do agree with them not being good for heavy traffic areas. Cities: Skylines taught me a ton about traffic and how it reacts to types of intersections. It's funny how much you can learn from a game.

The one closest to me is more of a ovalabout but it fixed the traffic issues in the area: https://www.google.com/maps/@40.7016153,-80.2851507,155m/data=!3m1!1e3
