Okla. Stat. tit. 69, § 69-1210: Culverts, driveways, mailboxes and stock-pass fences

excepted - Approval by Commission required.

Sections 1208 through 1211 shall not prevent the construction or

maintenance of any culvert or driveway as a means of ingress and

egress to private property, or prevent the placing of mailboxes or

fences to stock-passes on any highway right-of-way. The Commission

may regulate the construction and maintenance of such culverts,

driveways, fences to stock-passes, and mailboxes with due regard to

the safety of the traveling public and proper maintenance of the

highway. No culvert, driveway, fence to stock-pass, or mailbox

shall be constructed or maintained on the right-of-way of any

designated state or federal highway by any person without the

approval of the Commission, and the Commission may remove without

notice any such culvert, driveway, fence to stock-pass, or mailbox

constructed or maintained without first obtaining such approval when

in its judgment such culvert, driveway, fence to stock-pass, or

mailbox is dangerous to the traveling public or interferes with

proper drainage or maintenance of the highway.
