The Mountainland MPO Transportation Improvement Program or TIP is a compilation of projects sponsored by municipalities, Utah County, Utah Department of Transportation, Utah Transit Authority, and others utilizing various federal, state and local funding sources. The first four funding years in the TIP list projects and programs with identified funds that can be obligated for preliminary engineering, construction, and implementation. All capacity increasing projects in the TIP must come from the first phase of MPO transportation plan, TransPlan40. Any project not listed in the first phase of the plan must be amended into the plan before being added to the TIP. This requires an analysis of air quality and fiscal conformity.
