Projects

As of March 2026, the Regional Transportation Authority has delivered more than 1,050 projects funded as part of the 2006 voter-approved RTA plan. On March 10, Pima County voters approved a new plan and half-cent sales tax to fund it for the next 20 years. The RTA is working to accelerate project delivery on remaining 2006 plan projects and new projects from the first period of the new plan.

Overview

The Roadway, Bike/Pedestrian, Safety, Wildlife project information outlined below is for the 2006-voter approved Regional Transportation Authority plan. With the recent approval of a new regional transportation plan on March 10, 2026, the RTA will be implementing a new 20-year, $2.67 billion regional transportation plan.

The new plan features the following main transportation elements with programs and services that will be delivered over the next 20 years. The plan has four, five-year periods. Named projects will be scheduled to start construction within the plan period in which they are listed. The RTA is working with its member jurisdictions to accelerate project delivery.

Plan Elements

  1. Roadway (Multimodal) Corridor
    1. This element includes 31 new roadway improvement projects and seven projects from the 2006 plan that required voters approval due to project scope change or the need for additional funding. The 31 projects include five interchange projects. As projects come online, check back here for links to project websites.
  2. Safety, ADA and Active Transportation
    1. This element includes bikeway, pedestrian, traffic signal and related safety project across the Pima County region. Other safety features are embedded within all RTA plan projects.
  3. Arterial and Collector Roads, Pavement Rehabilitation
    1. Pavement projects in this element will rebuild roadways curb-to-curb. The RTA can address capital maintenance vs. routine maintenance, such as filling potholes. Routine maintenance of roadways is directly managed by local jurisdictions that own the local infrastructure.
  4. Environmental
    1. Critical wildlife linkages in this element will include culverts, fencing or other safety solutions to reduce motorist-wildlife collisions in natural habitat areas that intersect with busy roadways.
  5. Transit
    1. Transit funding from this element will apply to the RTA-funded transit services that started in 2006, including expanded evening and weekend bus services, related paratransit services, improved bus service frequencies, Sun Shuttle and Sun Shuttle dial-a-ride services that operate in neighborhood areas and connect to the main Sun Tran System. In addition, funding will support operations of the Sun Link streetcar in downtown Tucson, go toward new high-capacity transit improvements as well as new safety and security solutions on the regional bus system.

Watch for changes coming soon to the RTA website.

2006-2026 RTA Plan Projects

Roadways – More than half of the RTA tax revenues go toward multimodal corridor improvements to improve regional mobility and capacity. The 35 specific roadway projects identified in the RTA’s 20-year plan include new roads and bridges, intersection reconstruction, roadway improvements and Interstate 10 traffic interchange projects. The corridors are designed to help you get to where you need to go, whether you drive, use transit, walk or bike. Many corridor projects include bike lanes, multi-use paths and sidewalks to help integrate all modes of transportation within the regional network.

Bike/Pedestrian – Bicycle and pedestrian improvements provide additional travel choices in the regional transportation network and enhance safety for all users. Here are a few improvement highlights, through March 2026:

  • New signalized pedestrian crossings have been constructed throughout the region. To date, 84 crossings have been completed.
  • Of 250 miles of sidewalks planned, 183 miles have been completed so far.
  • More than 370 miles of bikes lanes have been constructed.
  • A popular improvement among cyclists and pedestrians is the El Paso and Southwestern Greenway that connects the Cities of Tucson and South Tucson.
  • An innovative RTA project is located along The Chuck Huckelberry Loop system: a bike/pedestrian bridge over Camino de la Tierra which is made from recycled girders.

Safety – When voters approved the RTA plan in 2006, safety for all system users was a priority in the region and remains so today. Safety is built into every project, including intersection, bridge and railroad crossing improvements, along with bus pullouts and signal technology upgrades. Of more than 200 bus pullouts planned, 180 have been completed through March 2026 along transit routes. Also, more than 200 intersections have been built across the greater Tucson region. Improvements address the needs of all commuters, including the elderly, students and people with disabilities.

Wildlife – Transportation-related wildlife linkages funded by the RTA help to protect both the motorists and wildlife across the region. These safety enhancements provide connectivity for a wide variety of desert wildlife including coyotes, mule deer, bighorn sheep, mountain lions, javelina, desert tortoise and snakes. A wildlife crossing can be a roadway overpass, underpass or drainage structure to allow animals to safely traverse the man-made barriers. Freestanding wildlife linkages and crossings are integrated with the roadway design of RTA improvement projects. These connections not only help prevent crashes that are dangerous to people and animals, they also allow wildlife to access their natural habitats safely.
