Last October 177 from Shawnee to the split with OK-3W was okay. Not great - but okay. A few sections are concrete slabs with some very slight heaving.
Several of our friends headed to the west side of Dallas/Fort Worth take that route and are happy with it. Avoids most of OKC and the traffic on I-35 - which isn't bad if not hitting rush hour.
They cut over on the Chickasaw Turnpike to OK-7 to I-35 - not going through Sulphur. Downtown Sulphur isn't horrible - but is a bit tight for towing.
Immediately south of Sulphur in the Chickasaw National Rec Area - a mid-steep climb on 2-lane road. Slow and watch for folks turning off. Some mild hills the next 10 miles.
Others will need to comment on US-169 and I-40 through Oklahoma (we're always crossing I-40 - not taking it).
