They have already started planning for the new interstate to serve as a bypass around Hearne/6. TXDOT has had at least 2 meetings in Hearne about it. They haven't decided the best route for it yet, though. The proposed path going to the west of Hearne (with 6 connecting on both sides) would mostly go through farmland. If it goes on the east side of Hearne, it would run behind the park and cemetery, crossing black jack rd. The current proposed route to the east does NOT have it joining FM2549, meaning it would carve a path through dozens of properties, including skirting my MIL's property (a lot of properties in that area are 5-25 acres).
Regardless, traffic in Hearne on 6 gets insane sometimes, and people desperately try to find alt routes by cutting through neighborhoods, and it's annoying.
