Construction of the $19.5 million Oracle Road widening project from Tangerine Road to Calle Concordia is 99 percent finished, according to a release from the Arizona Department of Transportation.
The project is closing down by Friday, Nov. 20, for the winter because of weather considerations. ADOT will finish rubberized paving on the 4.4-mile construction zone next spring, the release said.
Paving with rubberized asphalt is guided by temperature. Air must be between 85 to 95 degrees Fahrenheit for the material to mix and adhere to the surface properly. In Arizona, rubberized paving can be performed during April, May, September and October.
An unscheduled milling and paving from Tangerine Road to Pusch View Lane was added to the project, which pushed back the original timetable for the rubberized paving.
Work that has been completed includes an additional travel lane in each direction, new traffic signals, wider 10-foot shoulders, improved medians and left- and right-turn lanes, and new retaining walls and a sound wall over the Cañada del Oro with cattle brand artwork from the original ranches that make up modern-day Oro Valley.
Hunter Contracting was awarded the project and began construction May 14, 2008. Some 75 businesses were within the project corridor when roadwork began, and now the area has grown to accommodate more than 250 businesses, the release concluded.
