I've often wondered whether the Army is the reason 44 didn't get improved after the original road was built in 1964. The railroads prevent effective widening to the east. Maybe the Army didn't want to give up any of the base?
I doubt if the Army is an issue. Several other major military installations have very good super highway access. In Georgia I-185 effectively continues as a freeway for miles into Fort Benning. I-781 in Upstate New York was built as a connector for Fort Drum. Watertown nearby doesn't have any freeway loop or spur. Fort Bliss in the El Paso area is surrounded by Loop-375 and US-54 and is divided by the Spur 601 freeway. Fort Hood was part of the pitch to get the US-190 freeway in Killeen re-signed as I-14. The long term pitch for that route is connecting other military installations in the Deep South. To me it appear the military kind of likes super highway access to its installations.
In Lawton, I think the recent work they did to improve the Rogers Lane exit at I-44 was done partly to benefit the Army. The entrance to Fort Sill Gate 2 was re-configured in that project.
It would not be difficult to widen I-44 through the Key Gate area in Fort Sill. The old Rock Island rail line that came up into Lawton from Walters was decommissioned years ago. That rail line is what runs nearest to I-44 by Key Gate. The active BNSF line is adjacent to it about 40-50 yards to the East. If ODOT could get the old rail line ROW they would have more than enough room to add proper width shoulders or even additional lanes to I-44 there.
Of course there's plenty of room to expand Rogers Lane as well. The old "Artillery Village" housing area on the other side of the Rogers Lane sound wall was demolished 15 years ago. It's just unused, vacant land now.
I agree the Medicine Park area has some real growth and tourism potential, along with the nearby Wichita Mountains Wildlife refuge. A big problem with the MP area is a friend of mine, has a band that has performed twice there, and they were telling me that all the restaurants and bars close super early, like even before the concerts were over. I do not know if it is covid related or not, but does seem like they are missing out on major business opportunities.
Perhaps shorter hours could be a COVID-19 thing. I know the Park Tavern stays open til 2:00am on weekends and midnight during the week. Restaurant hours can vary. The Old Plantation stays open til 9:00pm. My thinking is if Medicine Park continues to gain popularity and new places to eat or socialize open the various night spots out there will stay open longer. Just be careful about the police out there. They'll pull you over if you're speeding just a little bit.
