Long-Range Transportation Plan (LRTP)

2026–2050 | Documents & Resources

The Southeast Regional Transportation Planning Organization (SERTPO) develops and maintains a Long-Range Transportation Plan (LRTP) to guide transportation planning, investment priorities, and regional coordination across 17 counties in southeastern Oklahoma.

The 2026–2050 LRTP addresses roadway safety, infrastructure preservation, public transportation, freight movement, economic development, accessibility, resilience, and long-term transportation needs.

Understanding Fiscal Constraint

Fiscal constraint helps ensure that transportation projects identified as funded in the LRTP have documented financial resources sufficient to cover their programmed costs.

The LRTP distinguishes between fiscally constrained programmed projects and illustrative, unfunded, or verification-pending transportation needs. This distinction supports transparent financial planning and responsible project prioritization.

Public Review & Regional Coordination

SERTPO encourages residents, local governments, Tribal governments, transportation providers, and regional partners to review transportation planning materials and participate in the planning process.

The LRTP and its supporting documents provide a framework for ongoing coordination, project development, funding opportunities, and future transportation improvements throughout southeastern Oklahoma.

Document status: Final Review. Final adoption and any subsequent amendments should be documented as part of SERTPO's official planning record.
