The third and final phase of the planned improvements for the Cortaro Farms Road/Magee Road corridor between Thornydale and Oracle roads will break ground in the coming weeks.

Rick Ellis, the Pima County Department of Transportation engineering manager, said work will begin once crews are done putting the finishing touches on Phase 2 - covering a section of Cortaro Farms between North Shannon and Thornydale roads.

Phase 3 will widen West Magee Road between North La Cañada Drive and Oracle Road to create a median-separated four-lane road. Advance utility work has already started, Ellis said.

A fact sheet for the project notes the five-mile corridor is more than a year behind schedule, with initial plans for Phase 3 to break ground in the spring of 2012.

Current plans project that the last phase of the project will take roughly 18 months to complete, with the entire stretch of road finally complete in early 2015.

The project is funded by the Regional Transportation Authority and is designed to improve current traffic conditions to meet future growth and install pedestrian and bicycle paths along the traffic corridor.

Down the road

• The Pima County Department of Transportation will begin milling and paving South Houghton Road from Andrade Road to just north of Camino del Toro starting today, with hours of operations from 6 a.m. to 6 p.m. Traffic will be directed through the work zone by flaggers and a pilot car.

• Contractors with Pima County and the Regional Transportation Authority will begin work on the West Ina and North Oracle roads Intersection Improvement Project starting today.

No initial lane closures are expected, but mobilizing heavy equipment and performing earthwork on the northeast corner of Ina and Oracle could result in minor delays for motorists.

• Motorists westbound on Interstate 10 east of Tucson will encounter nightly lane closures starting tonight as the Arizona Department of Transportation continues improvement work as part of the Marsh Station project.

• ADOT will also close the eastbound I-10 exit ramp to South Palo Verde Road on Tuesday and the left lane on eastbound I-10 at South Palo Verde Road on Wednesday for guardrail repair. Both closures will occur nightly from 7 p.m. to 5 a.m. the following morning.


Q: "I was pleased to return to find the paving project from River to Sunrise along Campbell had been completed. However, shortly after the divided section converges going south, the road has a subtle washboard surface and the pavement 'rolls/rocks' from side to side like a boat drifting on water. This continues almost down to Juan Paisano. Is this an acceptable completion of the project?" - Irma Ficzeri

A: Last summer, Pima County resurfaced Campbell Avenue from River Road to Skyline/Sunrise Drive with an asphalt overlay. The flaws that Irma writes about have surfaced because the roadway was resurfaced and not reconstructed. Existing base conditions often reappear to some degree, said Annabelle Valenzuela of the Pima County Department of Transportation.
