Planned Transportation Spending

Arizona

An examination of Arizona’s 2011-2015 Statewide Transportation Improvement Program* reveals that new road capacity projects account for the largest chunk of planned spending (52 percent). Transit projects follow, at 16 percent. Road maintenance/minor widening projects comprise 12 percent of the planned spending. Projects classified as “other,” which include information technology and general planning funds, make up 7 percent of the STIP. Safety projects** make up 4 percent of the STIP. Road or bridge projects with bicycle/pedestrian components (such as adding sidewalks when reconstructing a roadway) account for 3 percent of the STIP. Bicycle/pedestrian projects, bridge capacity expansion projects and bridge maintenance/replacement projects each make up 2 percent of the proposed spending.

* Arizona’s STIP does not include all metropolitan planning organizations’ projects. In addition to the STIP, TSTC used the individual Transportation Improvement Programs for the Maricopa Association of Governments (2011-2015) and Pima Association of Governments (2012-2016).
** Safety projects include a $252.7 million road widening project on I-10 from Prince Road to Ruthrauff Road. This project was funded in part by federal highway safety funds.
