24-2-111. Cooperation with cities in construction of streets connecting state highways and construction of storm sewers along streets designated as state highways.| (a) The transportation commission may cooperate with incorporated cities and towns in the construction of public streets and highways, including bridges and culverts, but excepting bypass routes, if the streets or highways constitute direct connections between sections of established state highways. All cooperative work shall be performed under the immediate control and supervision of the director of the department of transportation in accordance with plans and specifications prepared under the supervision of the director or the chief engineer, but no contract shall be let nor work commenced until sixty (60) days after the plans for the work have been submitted and approved by the legislative body of the incorporated city or town. The failure of the legislative body of the incorporated city or town to take official action approving or disapproving the plans within sixty (60) days shall constitute approval for the purpose of this section. The entire cost of construction of the streets and highways and the maintenance, including streets and highways currently in existence, shall be paid by the transportation commission with the following exceptions:  (i) The cost of construction of storm sewers along streets designated as state highways shall be paid by the transportation commission. If the city decides to connect other storm sewers with the one constructed by the commission, the commission shall only pay for the cost of a storm sewer needed to provide drainage for the street. If additional costs are incurred, the cities shall pay these additional costs. The city or town, if the population is over fifteen hundred (1,500) or more, shall pay all costs of, and be responsible for, the cleaning and maintenance of the storm sewers;  (ii) The city or town, if it has a population of fifteen hundred (1,500) or more, shall pay all costs of, and be responsible for, the cleaning, sweeping and washing of, and snow removal from the streets and highways. Notwithstanding any other provision of law, the transportation commission may contribute financial assistance to any city or town with a population between fifteen hundred (1,500) and five thousand (5,000) that is performing its duties under this paragraph in a total amount not to exceed twenty dollars ($20.00) per capita annually to the city or town;  (iii) The entire cost to the state of the construction, maintenance and acquisition of the necessary right-of-way for any highway route, which constitutes a bypass of any incorporated city or town, and which is constructed for the purpose of satisfying the highway construction standards established by the American Association of State Highway and Transportation Officials and approved by the federal highway administration including access control, regardless whether any portion lies within the corporate limits of any city or town, shall be paid by the transportation commission.
