To bad it would be to expensive to build a Kentucky style Parkway from Evansville to Northern Indiana
If there was not already a 4-lane highway from Gary all the way to Evansville, a toll-road *might* have merit. But there's simply not that much through traffic on US-41 to begin with, and with the existing 4-lane road there there little traffic left to support a toll road.
It would've been nice if US-41/IN-63 was fully limited access and didn't have stoplights and such, but over most of its length the traffic counts simply don't justify it. InDOT concentrating on uncorking US-30 and US-31 is the right move. Outside of Terra Haute and Evansville, there's few places on US-41 that would qualify as congested.
I think InDOT would do well to enact a policy with US-41 of eliminating stoplights and removing side road and driveway access when the opportunities arise. Posting a 65 mph speed limit outside of urban areas would also be helpful. But there's not that much US-41 honestly needs.
A Terre Haute bypass would also be helpful, though InDOT appears to not have put much thought into the idea, allowing the logical corridor along US-41/Hwy 46 north of I-70 to devolve into a commercial blob. Given the option, however, I'm fine with batting traffc through Terre Haute v.s. fighting it along I-465 around Indy.
Having driven both ends of US-41, I guess I can weigh in here.
I don't think that a stoplight removal campaign from stem to stern will drive the further use of the corridor.
The 4 lane job that US-41 has today was driven mostly by the fact that the ROW had really, really bad geometry and routing and required much more stop lights that it has today.
In the pre-interstate era, US-41 carried a significant load of CHI-IND traffic up to the US-52 split.
IN-63 was built due to a large level of resistance of road expansion from Attica south and the desire to use a more regular geography on the west side of the Wabash as compared to the east side.
Again in pre-Interstate days, US-41 from Terre Haute to Evansville was considered the best way for Evansville traffic to reach Indy.
I remember what it was like to drive through Emison, Busseron, the relief of finally reaching Sullivan north of Vincennes in the late 1960's. If one truck was in front of you, you were stuck. Such was life before the 4 lane came along.
Reaching Sullivan was like this huge relief.
Today?
I don't disagree that INDOT didn't give large amount of thought to a Terre Haute bypass. The Honey Creek district south of TH has exploded to the point INDOT had to find a way to get trucks on and off from I-70, hence that new stub that opened just a few years ago.
But none of the traffic planners then or today saw that there would be a large amount of traffic coming up or down US-41 that would have been classified as "pass through".
The interstate system went coming and going out of Chicago, simply went SE (I-65) to Indy or SW (I-55 and I-57) to Memphis and St Louis.
Terre Haute was just never considered a key point in north-south traffic flows. It was either a destination or a originator, but not part of a greater system to reach Chicago from the south.
