Highways, Roads and Bridges - As introduced, requires the department of transportation to allocate federal and state funds to rural planning organizations in parity with its allocation of such funds to metropolitan planning organizations. - Amends TCA Title 4; Title 54 and Title 64, Chapter 8.

SB 2180 requires Tennessee's Department of Transportation to allocate federal and state transportation funds to rural planning organizations (RPOs) in equal amounts compared to metropolitan planning organizations (MPOs) for transportation planning and projects. This directly affects rural communities and their planning groups, ensuring they receive funding parity with urban areas for highway and road planning. The bill mandates this equal allocation starting July 1, 2026, for funds applied for after that date. It amends Tennessee Code to define RPOs and MPOs and establishes this funding requirement as a legal standard.
