Surface Transportation Block Grant (STBG)

This page contains information about the Tri-County's STBG program and other major transportation infrastructure programs.

What is STBG?

The Surface Transportation Block Grant (STBG, formerly referred to as STU) are federal funds allocated annually to the urbanized area through IDOT which are programmed by TCRPC. STBG funds may be used to fully or partially fund regionally-significant roadway projects in the Metropolitan Planning Area (MPA). The MPA is the geographical area, which includes the existing urbanized area (defined by the Census Bureau) and the contiguous area expected to become urbanized within 20-years, in which the transportation planning process is carried out. 

Tri-County’s STBG Programs

Within the TCRPC STBG Program, there is the Traditional and Preservation Set-Aside Program. The Traditional Program encompasses (1) new road projects and (2) road reconstruction projects. The Preservation Set-Aside Program only encompasses road preservation projects. Both programs are announced in separate Call for Projects.
