The purpose of the Priority System Major Rehabilitation Program (PSMRP) is to provide funding for major rehabilitation projects on the priority system which restore the structural integrity and functional characteristics of the pavement. Acceptable strategies for pavement treatment include full depth pavement replacement (with rigid or flexible pavement), rubblize and roll, crack and seat, and un-bonded concrete overlays.

PSMRP funds can be used for preliminary engineering, right-of-way, and construction phases. Costs may include mainline bridges, right of way, utilities, and guardrail.
