The FFY 2026-27 and FFY 2027-28 STBG/CMAQ Program Guidelines were officially approved by the SCAG Regional Council on March 6. The Surface Transportation Block Grant (STBG) program supports projects that improve highways, bridges, roads, pedestrian infrastructure, and transit capital. The Congestion Mitigation and Air Quality (CMAQ) Improvement Program supports projects that reduce congestion and improve air quality, particularly in nonattainment areas.
