Changes coming for I35/Hwy 30 exit

It's about time. This probably should have happened years ago. With ISU enrollment spiking, this issue is only going to get worse.

I think the congestion is mainly caused by people people trying to get to the DSM airport. Definitely not easily accessible.


:jimlad:
 
Well there's no way to make that exit worse. The DOT should be ashamed of themselves on that one.

Safe to say when they put the interchange in during the 60's they never envisioned the amount of traffic and higher speeds.
 
This.

Though a 3rd lane would be nice just for when a truck passes another truck, we all don't have to wait going 63 mph

I'm always pleasantly surprised when I drive this stretch how nice the pace of traffic is, even on game days. People are flying back to DSM.

Sometimes it is good but it can also be just awful. I drive it every Monday, Wednesday, Friday. People like to sit in the left hand lane and it just backs everyone up
 
Little known fact of transportation engineering - increasing lanes does little, if nothing, to alleviate traffic concerns.

There are more cost effective ways to reduce congestion and it starts with better urban planning.

The problem with this is that by the time you've discovered your urban planning has created these problems in the first place, it's too late to do much about it. Other solutions need to be examined.

If additional lanes didn't make a difference, they would never be built. You cannot continue to funnel more and more traffic down the same inadequate roadways and expect there to not be issues. If you think adding lanes doesn't improve traffic concerns, imagine what traffic would be like had extra lanes NOT been built in rapidly growing areas.

When I lived in Ankeny and worked in Nevada, my days were always much better when I took back County roads to Nevada. Costs me about 5-10 minutes, but well worth it not having to deal with the I-35 morning left lane campers.

Wait, I live in Nevada and used to work in Ankeny.:eek:

Me too but the opposite direction. What the hell is wrong with those people? Are they that oblivious or just that inconsiderate?

This is because people demand it. Read opinions about roundabouts on CF - they are by far more efficient for a certain intersection traffic counts yet aren't always put in because the population screams about them. It's not always a case of doing what's best and shutting out popular opinion.

If places like Ankeny and Ames really wanted to fix this they would stop requiring developers to build in a street hierarchy pattern.

Believe it or not more intersections increases safety. That's a fact. But people want cul-de-sacs and 6 lane roads. That causes traffic problems

This is great news. I was just reading recently about all the upcoming changes to US 30 between Ames and Nevada and wondered if that intersection would ever get its own rebuild. I just hope the new flyover ramp is 2-lane, though that's probably too much to ask.

As for I-35 itself, I read somewhere where 3-lanes in each direction from DSM to Ames was on the table for discussion. (It sounded like a possibility, not imminent.) I agree that better planning could alleviate the need for more lanes or new roads but IMO that discussion starts after this stretch of interstate goes to 6 lanes. There's so much traffic, and so many trucks, going back and forth between Ames and DSM that I think it justifies it. Plus Ankeny and Ames are both growing and pulling traffic further north.

Currently I-35 moves reasonably well most of the time but as others have mentioned, all it takes is one truck passing another and suddenly traffic backs up for hundreds of yards. And God forbid there's ever an accident, which happens with increasing frequency these days, and it turns into a parking lot because there are so few exits - you're trapped. It probably would help if people started enforcing left lane obliviousness; if I had a dollar for every time I passed in the right lane someone camping out in the left lane cluelessly chatting away on a phone, I could retire tomorow.
 
I can't imagine being a truck driver during poor conditions and have to merge from northbound I35 onto Westbound 30. Going from 65-25 on that tiny little ramp is awful.
 
Isn't that what the flyover is for?

On a side note: is there a site that lists out all of these projects that are going on? Or business development projects (what's planning on going in where)?

If you're looking for talks about business development - I like to browse the UrbanDSM forums.

It's been pretty helpful when I've been curious about why they're pushing dirt or who's buying tracts of land...
 
I'm sold on the idea of having three lanes and semi's are not allowed in the far left passing lane. I've experienced this in Germany and it ran smooth.
 
My kids make fun of my old lady driving because if there is much traffic at all, I will either go up to 13th street or bail early at the Huxley exit. Very happy they are changing this.

Tell that BS to the people who travel between Lincoln and Omaha.
