Ohio DNR routes

[TheCatalyst31]

I visited Burr Oak State Park a week ago, and I saw a sign for Natural Resources Route 10:


I looked for more info on either the route or the system, and I confirmed that DNR Route 10 appears on the park map, but I couldn't find much more about the DNR routes in general. Does anyone else know more about this system and the routes in it?

Yes, they are statewide and seemingly random (I'm sure there is a system to it but I am not sure how they are numbered) They are also found in Headlands State Park at the north end of OH 44 for example.https://www.google.com/maps/@41.7552643,-81.2883902,3a,15y,247.25h,81.68t/data=!3m7!1e1!3m5!1s5-RPtgdchTz_iooYSK2XTg!2e0!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fcb_client%3Dmaps_sv.tactile%26w%3D900%26h%3D600%26pitch%3D8.31678100182755%26panoid%3D5-RPtgdchTz_iooYSK2XTg%26yaw%3D247.2534167422983!7i13312!8i6656?entry=ttu&g_ep=EgoyMDI1MDkwMy4wIKXMDSoASAFQAw%3D%3D
Also in north central Ohio, Mohican State Park has markers.  https://www.google.com/maps/@40.60536,-82.3041458,3a,15y,205.48h,88.94t/data=!3m7!1e1!3m5!1sK4-xDHFucibvMRmWrpfETg!2e0!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fcb_client%3Dmaps_sv.tactile%26w%3D900%26h%3D600%26pitch%3D1.062826162935977%26panoid%3DK4-xDHFucibvMRmWrpfETg%26yaw%3D205.478808185129!7i16384!8i8192?entry=ttu&g_ep=EgoyMDI1MDkwMy4wIKXMDSoASAFQAw%3D%3D
Various parks in Southeast Ohio (Hocking Hills) but I do not recall which roads I spotted them on

They're the roads used for navigating internally within state parks. The numbers are specific to that particular park.

Responsibility is split between ODNR and ODOT per Ohio Revised Code sections 1546.02 (ODNR can build roads) and 5511.05 (ODOT can build roads in state parks and Ohio History Connection sites).

I think I've seen DNR routes in John Bryan, Scioto Trail, and possibly Burr Oak State Parks.

This is spot on. Any ODNR property (state park, state forest, etc.) that has roads running within it will have Natural Resources road signs. While ODNR has its own engineers, they are focused on dams, mines, wells (water and oil/gas), and structures, so ODNR pays for ODOT's services when it comes to construction and maintenance of park roads.
