Designates the "Deputy Marshal David Thurman Memorial Highway" in McDonald County

HB 734 designates a specific segment of Interstate 49 in McDonald County as the "Deputy Marshal David Thurman Memorial Highway," running from U.S. Highway 71 south to the Arkansas/Missouri state line. The Missouri Department of Transportation must install and maintain appropriate signage for this memorial highway, with the department covering all associated costs. This bill does not alter traffic laws, funding, or regulations - it solely creates a permanent commemorative name for a public roadway. The designation directly affects travelers using this highway segment by renaming it in honor of Deputy Marshal David Thurman.
