State Transportation Improvement Program

The STIP is the transportation planning document developed by the Louisiana DOTD in accordance with 23 CFR 450.218. The purpose of the STIP is to provide for a fiscally sound, set (1-4 years) capital improvement plan for the state’s surface transportation program.

The STIP is not just a document, but is part of a fully integrated process for transportation planning and transportation project selection. The STIP is updated as needed to document the results of the project selection process. The STIP has been developed through a coordinated and cooperative process by DOTD involving citizens, elected officials, tribal governments, other state and federal agencies, each of Louisiana’s eleven metropolitan planning organizations and other interested organizations.

The STIP establishes schedules for a variety of projects, including:

• Highways and bridges
• Bicycle and pedestrian facilities
• Highway safety
• Congestion mitigation and air quality improvement
• Railroad crossing safety
• Highway operations and motorist services
• Public transportation
• Capacity Expansion, etc.

Louisiana operates under a federal fiscal year (Oct. 1–Sept. 30) and our STIP must be approved by the Federal Highway Administration and the Federal Transit Administration. This multi-year and multi-modal program identifies the transportation projects that have been through an inclusive and ongoing public involvement process.
