It's nice to see the interchange of WI 60 and the triplex getting modernized. Those parclo B2's sure were popular back when they built I-90 from Illinois to The Dells. They converted all of them to diamonds south of Madison last decade as part of that big project. Now they're starting to chip away at the last ones north of Madison, it would seem.
In other holiday weekend observations, I'm struck by the change in character of US 53 north of Rice Lake when you transition from the freeway constructed in the 70's to the expressway constructed in the 80's. The big sweeping curves and wide r/w with long, steel-girdered overpasses gives way to a more curvy 'tighter-feeling' facility with, of course, all the cross traffic and stuff. To be expected for most of it as the expressway was built on-alignment of the old two lane highway.
Though I look at the Spooner bypass section and think about the missed opportunities there. If my memory is right, it was built contemporaneously with US 51's super-2 bypass of Tomahawk in the early 80's. But over there, they had the foresight to preserve as much access control as they could so that two decades later, it was a cinch to twin that stretch and have it be a freeway. At Spooner, however, this long stretch of new (at the time) terrain four lane highway was built lousy with cross roads and no effort to grab up the r/w for future full access control. They even made it worse by putting that veterans cemetery right off the highway with additional at-grades. Woulda, coulda, shoulda, I suppose.
Anyway, the whole dynamic illustrates how highways were built pre and post NEPA. And I find that interesting.
