Why are these an issue for anyone that can read a traffic sign?

Because these types of interchanges don't exist in any major cities. I'm not worried about my ability to comprehend and read traffic signs. I'm worried about the cars around me and their ability to comprehend/read the traffic signs.

Is this thing really that difficult to navigate? Are we having big numbers of wrecks at 60/2818 that I'm not hearing about? I got all the whining when it was first proposed and even after it was done but is it really a problem now? Thinking back to what we had before this is infinitely better, isn't it?

I don't know. The soccer moms in Wilco figured out the one in Round Rock real damn quick.
I was very nervous the first time I went through the other one until I figured out that all I have to do is drive the direction the roads are pointing.
Not sure I'm opposed to this at all. Traffic on University headed east gets wayyyyy backed up at that left turn onto the frontage road. If this helps ease that, good.
And the one at University and 2818 has worked just fine, despite early hand wringing.

It worked so well the first time in CoCS.
They replaced two (stoplight) controlled intersections with two (stoplight) controlled intersections (only backwards).

The logic about traffic backups turning south on 6 is pretty weak. There are many ways to fix that. The primary benefits of DDI are unencumbered left turns.
I did not like the change at 2818 because previously traffic going straight on 60 did not have to stop, however in this case I only see it as an improvement. I hope we have enough room for these at 30 and Briarcrest intersections too.

This. Right. Here.
And cut the number of accidents down by a huge amount. I'm through that area very regularly. There used to be accidents there almost daily from turning traffic. I can't remember seeing one since the DD was created.
The only accidents I've seen at the 60x2818 DD both involved people trying to take one of the right turning ramps too fast in the rain.
And one DWI who somehow managed to get past a whole bunch of barricades and flashing lights while they were building the thing.

There are at least two in the Austin area.
My only question is the cost. How could this cost $284MM?
Wouldn't some overpasses on 2818 be better use of those funds? They short changed the needed 2818 improvements with a double u turn system….

Vegas is building one right now.
That's a lot of money. Luckily this one seems long enough to work well. The 2818 one will become very congested someday. They work well when the bridge length is long enough for a "full load" to be a long full light cycle. The 2812 bridge is not long enough for that from what I have heard from DOT engineers.

Agree, but I wonder what that light at Glenhaven is going to do to screw up West bound traffic? Does it risk stacking up traffic on those smoothly flowing overpass lanes?
'Infinitely' is an awful strong word. Maybe it's bc I grew up just west of that interchange and felt with the old style for 25 yrs, but maybe except for game days, it now seems like a bit more of a hinderance.

There was no way that the overpass at University/60 and 2818 wasn't going to have to controlled intersections.doubledog said:

The goal of that reconstruction was to get rid of the turn lanes on 2818. And the accidents caused by people turning left off of 2818 onto University / 60.
Anyone that leaves that out is either being obtuse or they didn't know the goal of the project.

I guess they're becoming more popular.Quote:
There are more in MoPac at Slaughter Lane in Austin; Sam Rayburn Tollway at South Colony Drive in The Colony; LP 375 at SP 601 in El Paso; IH 35 at University Boulevard in Round Rock; and one at Loop 1604 at US 281 in San Antonio, Colwell said.
By the timeline looks like this will go in around the time they add two more lanes to the bypass. May as well get it all done at once. Months of slowdowns ahead.ratfacemcdougal said:

That's my thought too. But, it's only going to get worse so we might as well rip off the band-aid. Start asap on the extra lanes and the DD. might as well add the George bush/welborn train tunnel too. Let's go!
Will be nice. The other one in town has significantly cut crashes. Although I don't think there are all that many crashes at this intersection currently.

The 2818 portion of that interchange is immeasurably safer than it was before the change. The University portion wasn't too terribly bad but the 2818 portion was dangerous.

This is simply false. The 2818 portion of the old interchange was just dangerous.

I saw this as part of the plan to make Highway 6 three lanes in each direction. Maybe that figure is part of the number.
That article is missing lots of relevant information. The article doesn't even mention the highway 6 widening project. This interchange work is part of that project. Current plans are to widen highway 6 to 6 lanes then do improvements at all of the interchanges. That 284 million price tag and timeline are for the entire project, not just this one interchange. For reference the 2818 widening project is between 40-50 million. The DDI at university has been in the plans for about 2 years.PS3D said:lockett93 said:

I don't understand either. I go through the one at 2818/University once or twice a day in different directions and I think it's great. Beats having cars turning left across speeding traffic with no street light especially in the dark.Stupe said:

I assisted on two accidents in front of me when before the sun was up drivers going north on 2818 were attempting to turn left across two lanes of 2818 to get on the entry ramp to go west on 60. Stupid drivers, yes, but accidents occurred there regularly.Smeghead4761 said:

The same risk was present with people going north on 2818 trying to turn left onto the ramp to go east on Unv. I called TEXDOT multiple times to get multiple street lights over that intersection without any success.
I go through there a couple of times a day most days and have no issues now.
There's a few around the country.techno-ag said:From the article:Red Pear BCS Luke said:Stupe said:

There may even be a worse case. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves." - Sir Winston Churchill
