The Tangerine Road Corridor Project extends approximately 10 miles from its interchange with Interstate 10 in Marana, Arizona east to La CaÃ±ada Drive in Oro Valley. The major features of the project include widening the roadway to four lanes, adding landscaped medians to accommodate future traffic demands, eliminating existing dip crossings that accommodate stormwater and upgrading culverts to provide 100-year flood access, providing facilities for pedestrian and bicycle traffic, installing additional turn lanes and signalization at key intersections, and providing wildlife crossing areas.
The project consists of two equal-length segments for the purposes of construction. Segment 1, completed in 2018, extends from Dove Mountain Blvd. to La CaÃ±ada Drive. Segment 2, expected to start construction in 2022, continues from Dove Mountain Blvd. to I-10.
The project provides enhanced safety improvements compared with standard rural road improvements. It improves safety and access by eliminating dip crossings and providing shoulders for bicycle travel and sidewalks for pedestrians, connects two state highway facilities, and provides more direct access to I-10.
Tangerine Road runs through the Town of Marana, Pima County, and the Town of Oro Valley. These three governing agencies worked together on this project, with assistance from the Regional Transportation Authority, the fiscal manager for the 20-year regional transportation plan and the voter-approved local option sales tax within Pima County.
The Tangerine Road Corridor used two methods of value capture to pay for the project. For the RTA funding, a half-cent sales tax was introduced in 2006 to pay for infrastructure projects, leading to a multi-billion dollar infrastructure improvement plan that included the Tangerine Road Corridor. The Town of Marana, Arizona used special assessment bonds, through the Tangerine Farms Road Improvement District to cover its portion of the necessary funding.
