I had the day off and took a round-trip ride on WI 26 between Oshkosh and I-39/90 at Janesville on Sunday (2010-08-22).
-YES, those four-way STOP signs between Waupun and WI 60 are beyond annoying! No relief on that using County 'A' on that point, there are a few on that road, too.
-Some preliminary ROW clearance work has been done for the four-lane upgrades on the part between WI 60 and Watertown (the WI 16/26 duplex section).
-Construction on the westside Watertown bypass freeway is well under way, including an interesting bridge on Watertown's south side. As it sits now, it is mostly hidden from view from existing WI 26, barely visible behind a small glacial esker. WI 19 is currently *closed* at its WI 26 interchange, which will include roundabouts at the ramp intersections. These are getting popular in the state, the US 41 work in both the Oshkosh-Neenah and Green Bay metro areas will include OODLES of them! This bypass looks to be on schedule to open in late 2011.
-MUCH grading has been done on the remaining two-lane sections between Watertown and Jefferson. Nope, there is no work nor any known near-term plans to eliminate the stop-and-go lights in the I-94 area at Johnson Creek.

-The westside Jefferson bypass freeway looks to be on schedule to open later on this year. As part of that project, the interchange at the north end of Fort Atkinson is being realigned to a much greater extent than I was at first expecting.
-Grading for upgrading the WI 26 Fort Atkinson bypass from a 'super-two' to a full four-lane freeway is under way, the part at the north end (including bridging those two BAD crossroads) looks to be on track to be done this fall, along with the Jefferson bypass. South of US 12, it'll be at least another year as this part includes a new bridge over the Rock River for the southbound side of the highway, work on which is just under way.
-The part between Fort Atkinson and Milton is showing a few signs of some ROW clearance.
-The only work on the planned Milton bypass freeway so far (to go around the city's east side) is a pair of roundabouts for the WI 26 interchange ramps on the newly relocated part of WI 59 as it heads eastward out of town. There is also a roundabout at the new WI 59/County 'M' intersection.
-Nope, just like at Johnson Creek, there are no known near-term plans to eliminate the intersections and stop-and-go lights near I-39/90 in and near Janesville.

-A major natural gas pipeline is being constructed across Janesville's far north side.
