The Regional Transportation Authority’s 20-year plan, which voters approved in 2006, includes roadway, transit, safety, environmental and economic vitality projects and services. As of September 2023, more than 960 RTA improvement projects and services, including new intersections, sidewalks, bike paths, signal technology and bus pullouts, have been completed or implemented across the region.

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.


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 May 2022:

  • New signalized pedestrian crossings have been constructed throughout the region. To date, 78 out of 80 promised have been delivered.
  • Of 250 miles of sidewalks planned, 179 miles have been completed so far.
  • More than 366 miles of bikes lanes have been constructed with another 250 miles to go in the current RTA plan.
  • 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 Huckleberry Loop system: a bike/pedestrian bridge over Camino de la Tierra which is made from recycled girders.


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, more than 163 have been completed along transit routes through May 2022. Of 200 intersections promised, 195 have been built across the greater Tucson region. Improvements address the needs of all commuters, including the elderly, students and people with disabilities.


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.
