1) This belongs in Fictional Highways.
The number may be, but since the thread is discussing that segment for interstate upgrade and it is indeed an official proposal, it's not fictional.
2) The Freer to Corpus Christi segment of SH 44 is already integrated into the I-69 system. An I-x69 is more suitable for that segment if it is upgraded and the rest of the I-69 system is built.
Perhaps, though just like I-6 it's pure speculation.
I-2 is part of the I-69 system, though did not receive an I-x69 designation, rather a new 2di.[/quote]
3) A simpler idea would be to just eliminate the designation for I-69W between Freer and Victoria and simply 4-lane that section as an arterial highway with freeway bypasses at certain points, transfer I-69W to SH 44 from Freer to Robstown where it would meet I-69E/US 77, and just make that section from there I-69.
Agreed, and I even question the need for 4 lanes in many areas. The two lanes seems adequate, and through traffic would likely divert to I-69E and a SH-44 interstate if constructed, so at that point US-59 is serving local traffic.
20 miles of US-59 west of Victoria is currently 75 mph 4 lane divided highway. The remainder west of there is 75 mph super-2.
Save I-6 for the renumber of I-49 South in Louisiana + a Lafayette bypass.
Seems fine as is with I-49.
I wish & hope Louisiana will number I-49 south of Lafayette to I-6. So much money would be saved not renumbering the exits on current I-49.
That's a minor expense. Indiana recently had to renumber I-69 exits to account for the 200 mile southern extension.
