Collinsville OK is about 23 miles straight N of Tulsa, and on a "freeway" (multilane each way) road (US 169), so it should be pretty easy to get to from Tulsa if there's anything going on there.

It's actually just off the main road between Coffeyville KS and Tulsa OK, a little closer to Tulsa. My rather dated map shows the multilane only extends about 20 miles N out of Tulsa, but the highway, even if 2-lane the rest of the way should be pretty good, and may even have been improved since my map program came out (1997).
