House Bill No. 1125 amends existing transportation law regarding the construction, improvement, and maintenance of municipal streets in Oklahoma. The bill specifies that the Oklahoma Department of Transportation (ODOT) is required to pay for and replace curbs, inlets, inlet grates, inlet hoods, and inlet structures in municipalities with a population of one hundred thousand or less, as part of projects that involve municipal streets that are continuations of the state or federal highway system. The bill also clarifies that ODOT will not cover costs associated with mowing right-of-ways or stormwater drainage systems outside the back of the curb, and municipalities are responsible for restoring the highway surface if they perform construction or maintenance operations.

Additionally, the bill mandates that when ODOT undertakes a project, it must bear the full cost of installing, repairing, replacing, or maintaining the specified infrastructure as part of the project scope. It also requires ODOT to amend existing administrative rules that currently exclude these activities from the scope of such projects. The effective date for this legislation is set for November 1, 2025.
