The majority of intersections along Capitol Drive (WI-190) include inefficient left-turn phases. Michigan would be going backwards if they converted their Michigan left corridors to resemble Capitol Drive.

Ummm the West Bottoms are one of those former industrial districts where the gritty look is part of what makes it interesting. And not cheap. (Well by Kansas City standards, anyway.)

St. Croix Crossing

The St. Croix Crossing at the Minnesota / Wisconsin state line near Stillwater. It is the third extradosed bridge in the United States.

Were these former combined road-rail bridges?

That is the old west bottoms neighborhood. An old industrial/railroad area that used to be a MASSIVE stockyard. All the cattle raised in the midwest was put on trains here and shipped to the chicago.

Here is the 12th street viaduct back in 1951.


And the whole area 100+ years ago


It's in a floodplain and a very steep hill up to downtown.

Isn't this Michelle Bachmann's folly? The one that just makes no sense from any technical perspective whatsoever?

I don't know that particular story, but this bridge will connect two four lane divided highways (WIS-64 is pretty much a freeway) and the current bridge has a poor rating.

The extradosed bridge design offers no real cost advantages, but isn't much more expensive than other solutions either. In this case, the extradosed bridge allows longer spans while maintaining low pylon height, to reduce the impact on the landscape and still have some kind of landmark span.

North Tarrant Express, Texas

The SH 121 / SH 183 interchange in Bedford, Texas (a suburb of Fort Worth). This project was completed last year.

Well it isn't really about the technology used in construction -- it's whether or not traffic would be there to support it in the first place. (And by the way, Minnesota is shot through with freeway-grade state highways that have absurdly low AADT.)

We're talking about a state that has more in common with Finland but thinks it needs Netherlands-level transportation spending here.

(And BTW yep, the Stillwater bridge -- at a projected 16k vehicles/day -- is the one I think it is.)

EDIT: 16k veh/d should be -- if 90% of usage is in daylight hours with given the fact it's in the middle of bum**** nowhere = no real commute peak ... round back up ... a max throughput of a thousand vehicles an hour, maybe? A two-lane road can handle that.

EDIT EDIT: Ohhh this project is worse than I thought. This is gonna actually be a ginormous subsidy for Wisconsin sprawl developers. Yuck.

Probably should have just built a New Bridge near the old bridge...

I had to made a slight change of plans after I realized there is an unpaved gap in one of the UT state roads I was planning to take.

What are the inside lanes next to the median on SH 183? I remember driving this all the time when they just started construction.

Apparently. Before all the construction, all of it was free. Of course, all of it was jam packed during rush hour.
