The video starts at I-40 and ends at OK 9. Includes a segment that is being dualled, the Wildhorse Mountain crossing, and the Arkansas River bridge.
I drove through yesterday and the future NB concrete lanes are poured except for about 1/4 mile on the north end. Shoulders haven't been built yet. Hopefully it won't be long until they open the new lanes as a temporary 2 lane road while they rehabilitate the old lanes (future SB lanes.)
