Not quite -- parts of it are between LBJ and the Red River, but between
about Allen and Sherman it needs some fixing to qualify for Interstate
funding (like wider shoulders and medians), and it needs an expansion
through Sherman to the most recently-opened section around Denison. North
of that, you've got almost a hundred miles of new construction that'll need
to be done, all the way up to the Indian Nation Turnpike just southwest of
McAlester. There's sufficient space to do that along the existing roadway,
for the most part, but a new bypass will be needed for Atoka, and the
Turnpike connection will have to be redesigned.
(It may happen, and I'd like to see it done, but I wouldn't expect it to
happen for at least another decade or so, at the soonest.)

To the State Line, yes... even to near Durant it IS Interstate
quality. But Bus 69 to Durant is an at grade intersection.
AFAIK, there are NO plans to extend I-45 though.
As far as road numbering goes, there are no plans. But the stretch between
Tulsa and Dallas will eventually be 100% limited access highway within the
next few years.
US-75 from downtown Dallas up to Sherman is an Interstate quality facility
and even featured a faster speed limit for years. Before the massive speed
limit change in 1995 for roads across the country, US-75 north of Dallas was
the only non-Interstate designated road I had encountered with a 65mph
"rural Interstate" speed limit.
The Oklahoma Turnpike Authority will build one turnpike from the south end
of Tulsa along US-75 to meet I-40 and the Indian Nation Turnpike in
Henrietta. From McAlester (where US-69/US-75 spur off toward Dallas) there
is a new turnpike being proposed to run from there down to Durant. There is
a small amount of opposition to this road being built on the part of some
business people in one small town along the existing four lane that would be
bypassed by the new turnpike.
I would suspect the last leg to get upgraded to Interstate quality would be
the four lane sections south of Durant with at-grade intersections. That's
because that section would likely not be able to be upgraded with toll
access and instead be a "free" section of roadway.
Overall, I do think I-45 should be extended northward to Tulsa and farther
up into Kansas to the Kansas City metro area. I-35 will have so much NAFTA
traffic on its own without having so much traffic from southeast Texas areas
like Houston using the road to get to Kansas City and points farther north.
US-281 to the west of I-35 from San Antonio to Wichita Falls will have to be
at least upgraded to a four lane road with at-grade intersections if not as
a new Interstate highway altogether. It can function as a west relief route
for I-35 and I-45 can work off to the east. The proposed I-69 and I-49
routes will also help make the system overall work better.
