The Long Range Transportation Plan (LRTP) is prepared for the Peoria-Pekin Urbanized Area Transportation Study (PPUATS) every five years, and represents the programming of transportation improvements for the years 2010-2035.

The Big Plan is an integrated plan for the Tri County region that bridges the gaps between transportation, land use, and environmental planning.  Through the development of this plan, five themes were identified as key mutual priorities for the region's future:  agriculture preservation, balanced growth, economic development, environmental stewardship, and transportation infrastructure.
