Section 730:35-7-3 - Traffic control responsibilities

(a) On the state highway system within cities and towns, the Department shall pay for the erection and maintenance of all traffic control signs, pavement markings, and traffic control devices, except as noted in 730:35-1-11.

(b) Following written approval by the Director, time parking restriction signs, parking space limit markings, crosswalks, and stop lines shall be purchased, installed, and maintained in a satisfactory condition by the individual governing body or school district involved. All such devices shall be in conformance with 730:35-7-2(a). This section shall not be construed to prohibit the Department from installing these or other special or supplemental signs or pavement markings where deemed necessary for proper operation and safety.

(c) The construction and maintenance of all traffic signs and markings on the interstate highway system shall be the responsibility of the Oklahoma Department of Transportation or the Oklahoma Transportation Authority.

(d) When Federal Funds are not available, the Oklahoma Transportation Commission shall participate in the cost of construction of warranted traffic control signals in cities, towns, or communities, without regard to population, on a 50-50 ratio of total cost where such traffic control signals are installed or erected on the state highway system. The city's or town's share of the Engineer's Estimate, or low bid, shall be on deposit with the Department's Comptroller prior to actual award of the contract.

(e) When Federal Funds are utilized, the local government shall participate in the cost based on the funding ratio designated by the Federal-aid program requirements. When it can be shown that the traffic control signal installation can be done more economically and quickly by the city concerned, the Director may enter into an agreement with the city to provide the project engineering in accordance with Transportation Department Policies and Standards.

(f) Prior to the installation of traffic control signals, the city or town where the signal is to be installed shall execute an agreement whereby the city or town shall furnish all maintenance and pay all power and electricity costs.

(g) Traffic control devices erected on the state highway system shall become the permanent property of the Oklahoma Department of Transportation, except, where by formal agreement, they become joint property of the city-county, and state, or the sole property of the city-county.
