Okla. Stat. tit. 11, § 11-36-117: Sidewalks - Construction by railroad - Maintenance of

improvements.

The municipality may require, in addition to the improvement of

streets as required in Section 36-116 of this title, that a railway

company shall construct sidewalks crossing the tracks or right-of-

way of its railways, with such material as the municipality may

require by ordinance, upon either or both sides of the street; and

that the railway company shall maintain such improvements, keeping

the same in repair at its own expense, using for such purpose the

same material as is used for the original paving, graveling or

macadamizing, or sidewalks, or such other material as the

municipality may order.
