re: I shite a lot on Baton Rouge (and it's still bad), but the new College Dr exit is great

quote:

---

It looks like people on College can turn right at Corporate or go straight. I don’t see what issue is.

Which means if someone is in the right lane and going straight it delays everyone trying to turn right onto Corporate. This is some Houston metro bullshite. Houston has a lot of places without designated right turn lanes. One thing Louisiana has been good about in the past is always having designated right turn lanes.

How intuitive does it need to be? There's literally a giant sign on the exit that spells out what each of the lanes is for. You don't need to intuit anything.

---

I mean.. 99% of the time when you’re on an off-ramp where one lane veers right while the rest go straight to a light, the lane that veers right will allow you to turn right onto the cross street. I’m sure there are other interchanges similar to the new College Drive interchange, but I can’t think of one offhand; every example in the area that I can think of works the way I’ve described.

So while, yes, there are big signs:



..I still don’t really think it’s a stretch to say the interchange is “less intuitive” than it was before.

Is it unfathomably complicated? Obviously not. People will adjust. It’s just not what you would expect.

That said, it's only been configured this way for a little bit - College Dr is a cluster and has been for years. The work done on the interstate was not done to fix that, and I don't really think that it made College drive any worse.

---

I don’t really know why they would have configured the exit this way if not to minimize weaving/backups on College. It doesn’t seem like forcing the folks in the far right lane to turn onto Corporate would help traffic on the interstate. But maybe I’m missing something.

Well BOO-frickin-HOO. They can have some frickin patience and wait a little bit for the common good or they can stay off College Drive period.

Yes. Let’s keep people trying to get off of college on the street for another light cycle while backing traffic up under the overpass, effectively gridlocking 2 lights.

I remember watching the construction as I lived nearby...it was fubar from the start.

I like eggs too!

I don’t really see how it causes backup on I-12 in the long run, once everyone is used to it and the last bit of construction shite is gone. Anyone trying to get off on College gets to exit earlier now. Anyone trying to continue on I-10 no longer has a shite ton of I-10 traffic cutting across their lanes to exit on College.

The only people I can see being affected negatively are those who are on I-12 trying to exit on Acadian, since they now have to cross two lanes to get to the exit. But it still seems like that should affect I-12 traffic less than people from I-10 crossing 2 lanes in front of them to exit on both College and Acadian.

Gonna be nice in 2034 when I-10 is 4x4 from the split to 110 and it's smooth sailing through Baton Rouge.

---

Recently went up to the Ozarks. This is a super nice situation from the Hammerschmidt tunnel up through Missouri it's just like a smooth sailing mission everyone's going 75 mph at least and nobody's having any problems.

If that could only ever happen here

quote:

---

I-12 was three lane all the way through the split and to the 110 split.

---

But it wasn’t. The right lane was exit only at College, and the middle lane was exit only at Acadian. Only the left lane actually continued past Acadian.

Now the right lane is still exit only at College but both of the other two lanes continue all the way to the bridge.

quote:

---

They alleviated the traffic on 10 by giving 10 the extra lanes that 12 enjoyed. It's pretty simple.

---

Well nobody can ride down the College exit anymore, because both I-10 and I-12 now exit for College before the merge (the entire point of the project).

The right lane on I-10 is now an exit only at Acadian, but I don’t really see how that part moves the congestion from I-10 to I-12 considering that all of the drivers in the right lane on 10 eventually have to merge over into the only remaining I-10 lane unless they’re exiting at Acadian.

Of course this will all change once the larger expansion is complete - both I-10 and I-12 will each have 2 lanes that continue from the merge all the way to the 10/110 split.

In any case my point is this: I-12 WB had one continuous lane past Acadian and it had drivers crossing both lanes to get to College from I-10. Now it has 2 continuous lanes past Acadian and drivers don’t have to cross them to get to College. If I-12 is backed up more than normal right now, I would contend that this has more to do with residual construction impacts (along with possible impacts from the large expansion project) than the design of the flyover project. If anything, the flyover project should reduce congestion on both I-10 and I-12 WB over the long run.
