Any municipality or Metropolitan Planning Organization may, in cooperation with TxDOT, develop an access management plan for a specified state highway segment for the purposes of preserving or enhancing that highway's safe and efficient operation. Once adopted by the affected agencies, such plans will form the basis for all future access connection locations. Priority in developing corridor access management plans should be placed on those facilities with high traffic volumes or those that provide important statewide or regional connectivity and mobility, such as hurricane evacuation routes, relief routes, and NAFTA corridors.
