The 20-year RTA plan includes 35 corridor improvement projects across the greater Tucson region. The projects include roadway widening, sidewalk, bike lane, intersections, bus pullout, landscape, drainage and public art improvements.
Corridors specified in the RTA plan
Of the 35 corridor projects, 13 have been completed and nine are partially complete. Many of the projects are built in phases as RTA sales tax collections and other regional funds becomes available. The 20-year plan has four five-year periods that identify construction start periods. The RTA is currently in the third period, FY 2017 through FY 2021. The fourth period is FY 2022 through FY 2026.
1st Avenue, Orange Grove Road to Ina Road (RTA Ballot #13)
This project will occur in the fourth period of the RTA plan between fiscal years 2022 and 2026. Plans for First Avenue between Orange Grove Road and Ina Road call for widening the roadway to four lanes and adding bike lanes and sidewalks.
1st Avenue, River Road to Grant Road (RTA Ballot #14)
Voters approved this widening project to include a six-lane roadway with bike lanes and sidewalks. This is a third-period project, scheduled to begin between fiscal years 2017 and 2021.
22nd Street, Camino Seco to Houghton Road (RTA Ballot #30)
22nd Street will be widened to four lanes with bicycle lanes and sidewalks. This is a fourth-period project to begin between fiscal years 2022 and 2026.
22nd Street, I-10 to Tucson Boulevard/Barraza Aviation Parkway (RTA Ballot #19)
A new intersection at Kino Parkway and 22nd Street was completed in fall of 2015. Future improvements will widen 22nd Street to three lanes in each direction. Additional project elements include access to nearby businesses and neighborhoods, drainage, street lighting, sidewalks, landscaping, bicycle and pedestrian improvements, transit facilities and public artwork.
Phase 2 is the section of roadway from Kino Parkway to Tucson Boulevard. Design of the new bridge over the Union Pacific Railroad tracks will require coordination with Union Pacific Railroad. Utility coordination activities have been initiated. A construction time frame is still to be determined.
Phase 3 from Kino Parkway to Interstate 10 is expected to advance in the fourth period (FY 2022-2026) of the RTA plan.
