2006 Plan Projects
The 20-year RTA plan, approved by Pima County voters in 2006 included 35 roadway corridor improvement projects across the greater Tucson region. The corridor projects included roadway widening, sidewalk, bike lane, intersection, bus pullout, landscape, drainage and public art improvements.
Corridors specified in the 2006 RTA plan
Of the 35 corridor projects, 19 have been fully completed, 7 are partially complete, 2 are under construction, and 6 have design activities underway as of May 2026. Many of the projects were built in phases as RTA sales tax collections and other regional funds became available.

Let’s find a way to distinguish/label between “completed” projects and “pending completion” projects or Part of 2026 RTA Plan.
