Indiana Notes

[NWI_Irish96]

Technically, everything along US-30 west of US-421 (east of Valparaiso) is within 10 miles of the Toll Road.

If they're trying to stay within the terms of a non-compete clause, build a north-south toll road "extension" parallel to US-421 connecting the Toll Road to US-30, then upgrade US-30 east of there. Brand the new toll road as a US-421 bypass, arguing it's not intended for east-west traffic, despite it deliberately funneling traffic from the main Toll Road to a free US-30.

May be better to just build a new southern alignment for US 30 from about US 421 over to IN 49 that meets the 10 mile separation requirement.  IN 49 is three overpasses away from being a full freeway from US 30 to the Toll Road (not counting the stoplight at the Toll Road interchange).  I don't think that part of Indiana has grown enough yet to justify another freeway along US 421.

I agree - I did not realize that IN-49 is virtually a freeway between the Toll Road and US-30.

Yeah, if you just convert IN 49/Burlington Beach Rd, US 30/US 421 and US 30/IN 39 to interchanges, and maybe a couple other higher volume intersections into  J-turns, you have a pretty smooth route from the Toll Road to Plymouth.
