New Ina Road ramps to and from Interstate 10 are open in Marana

Orange Grove exit also reopens; work continues on widening Ina Road
April 16, 2019

PHOENIX ‒ Ramps connecting Ina Road with Interstate 10 in Marana have opened to traffic, completing the Arizona Department of Transportation’s renovation of a vital interchange in northwest Pima County.

adotThe new, larger interchange and associated improvements reduce congestion in a growing area while improving safety by eliminating the need for drivers on Ina Road to wait for passing trains many times each day.

Although the ramps are open, crews must complete final elements of the project. Lane restrictions are scheduled to continue for the next several weeks.

Work continues to widen Ina Road from I-10 west to the Santa Cruz River and connect the wider road to a new westbound bridge over the river. That part of the project is expected to be complete by June.

ADOT crews opened Ina Road over I-10 on March 15. Crews have worked since then to complete the ramps and put down new pavement along Ina Road and adjacent streets.

ADOT is overseeing $128 million in improvements, which are funded by the Federal Highway Administration, the Pima Association of Governments and the Regional Transportation Authority. The town of Marana is contributing $7.9 million toward the cost of the new bridges over the Santa Cruz River west of I-10.

This is the third I-10 interchange in the area to be renovated in recent years. At Ina Road as well as Prince Road and Twin Peaks, crews replaced underpasses at I-10 with bridges carrying traffic over the interstate and Union Pacific Railroad tracks. Construction is expected to begin this fall on a similar effort, at Ruthrauff Road.
