EDIT: and any news on the US 77/I-69 Driscoll and US 59/I-69 Nacogdoches bypasses too?
The work on I-69 at Nachogdoches was proceeding well when I drove through on September 7. See photos below. The section to the south of the elevated connector was not as far along but all right-of-way was cleared with work in progress.
Further south at Diboll, the forest was cleared from the right-of-way. As I've mentioned before, there is a tremendous amount of work still needing to be done to upgrade the corridor to Interstate standards all the way to Houston, and the projects in progress are addressing the worst slowdown locations.
