Memorial highways; designating the Charlie Kirk Memorial Highway. Effective date.

SB 1874 designates a specific section of U.S. Highway 287 in Cimmaron County as the "Charlie Kirk Memorial Highway," running from the intersection with U.S. Highway 56 near Boise City north to the Oklahoma-Colorado state line. The bill requires the Oklahoma Department of Transportation to install permanent markers bearing this name on the associated bridge. It becomes effective November 1, 2026, and has no substantive policy impact beyond the highway naming.
