Has there been any news about what the plan will be at the US 12-Hwy 188 intersection outside Sauk City? Here is the site but I haven't seen any updates on this.

I understand they are planning to start work on it in 2026.

I just noticed they are going to put a roundabout at the US 12/18 and County W intersection outside Deerfield. The plan was revealed a few days ago.

Eh. I don't hate roundabouts, but I am not sure that's a great place for one.

I wonder if they'll end up doing anything about the County BN intersection, which is the other big intersection on that stretch that's just a two-way stop.

They should probably install a roundabout at that intersection too. There was a corridor study for the US 12 corridor between CTH N and STH 26 between 2011 and 2014: https://wisconsindot.gov/Pages/projects/by-region/sw/12nto26/default.aspx. It had some interesting things in it, but of course did not have the one thing I'd like to do to the corridor: four-lane US 12 between CTH N and at least Cambridge.

No the one place where I hate them are on these high-speed rural roads. These roads are meant for that high speed. If I have to keep slowing down to go through roundabouts then they might as well just lower the speed limit. Frankly that part of Hwy 12 west of Cambridge should be 4 lane.

The handout from the presentation at the PIM says it will be a signalized intersection.

I had a feeling they would do that.

Vehicles traveling on 12/18 going west top a small hill before driving down to the intersection with Oak Park Rd/Highway W.  I have been rear ended turning north onto Oak Park Road.  They are REALLY going to have slow down speeds well ahead of the roundabout to prevent even more crashes.

Maybe they should bump the speed limit on US 12/18 down to 45 MPH when approaching the new CTH W/Oak Park Rd. roundabout, and raise it back to 55 MPH once clear of the intersection.

The better idea is to simply not build them on roads with a 55 MPH speed limit.

I don't necessarily disagree, but I am not sure what the alternatives are. A light or four-way stop isn't any better, and actually could be worse. They aren't going to four-lane that entire stretch or separate the grades.

Presently, there are no turn lanes at this junction.  It would certainly be better than the status quo to add turn lanes.

Oh. I was unaware that it didn't have turn lanes.

I would prefer actual turn lanes being added to the roadway, instead of the roadway being widened to two lanes just before to just after the intersection. Traditionally, rural two-lane roadways have lacked turn lanes, although in some cases that is being rectified (e.g. the soon-to-begin reconstruction of US 51 from US 12/18 in Madison to Interstate 39/90 east of Stoughton: https://wisconsindot.gov/Pages/projects/by-region/sw/us51-danecounty/default.aspx).

The alternative is leave it how it is.

What the hell was the purpose of the massive overpass and the reroute of Hwy 73 at US-12/18? I mean, if we're done with the pretense of US 12/18 being a through highway, then they could've just put in 2 roundabouts to solve the Hwy 73 issue and have been done with it.

Actually, it was two dangerous intersections.  It seemed like a good way to improve safety and traffic flow. The road is busy enough at peak hours to avoid putting in two roundabouts in close proximity.  Considering the rapid growth of the Madison CMSA (1M by 2030), it’s only going to get busier.
