Iowa Notes
bugo:
I have been through there on I-29 but I know very little about the topography of the area. I was just drawing a line on the map when I suggested a northern bypass.

It looks like there was a public meeting last month that discusses both bugo's and your alternatives for a potential bypass project that is currently unfunded.

I now realize I mistook bugo's idea (which you're right; the topography isn't very forgiving for that idea) for the northern bypass that was originally mentioned. I'm gonna fix that.
mvak36:
Iowa DOT will have a public meeting next week for the I-80/I-380 interchange: http://www.kcrg.com/content/news/Iowa-DOT-to-hold-public-information-meeting-on-I-80I-380-interchange-project-479157803.html
Here's the link to the project site: https://www.iowadot.gov/I80-I380
The goal of the project is to make the I-80/I-380 interchange into a turbine interchange. According to this staging map, construction will probably go till about 2024.
triplemultiplex:
The new I-74 bridge over the Mississippi River sort of fell off my radar a few years ago, but I see it's well underway.
Seems like a pretty standard look for a modern arch bridge.
This means in a couple years, we will see the demolition of not one, but two suspension bridges. That will be very unusual and might be worth seeing.
Has there ever been a demolition of a significant (ie not a footbridge) suspension bridge before in the US?

* Waldo Hancock Bridge in Maine
* US 18 Mississippi River bridges (east and west channels)
* The "twin" to the Silver Bridge?
* Think there was another one across the Ohio between Ohio and West Virginia
* Paseo Bridge in KC (I-29/I-35 over the Missouri River)
I don't believe there have been any with a span over a 1,000 feet yet.
(And before someone else suggest it, I am not counting any that collapsed and then had the debris and any parts still standing removed such as the first Tacoma Narrows Bridge)
