Frontage road work to begin east of I-19 at Canoa Ranch

Frontage road work to begin east of I-19 at Canoa Ranch

The Arizona Department of Transportation will begin work to widen a segment of the east frontage road of Interstate 19 at Canoa Ranch Road this week.

Motorists traveling on the frontage road adjacent to northbound I-19 in the Green Valley area can expect brief delays Mondays through Thursdays between 7 a.m. and 4 p.m. while crews widen approximately a half-mile of the shoulder between mileposts 35 and 36 (kilometers 58-60).

Traffic on the two-way frontage road will be controlled by flagging personnel in the work area, which will be reduced to one lane during work hours.

Bicyclists will have use of the frontage road during construction, but will need to share the road with vehicles and wait for the flagger to signal them to proceed. The posted speed limit on northbound I-19 approaching Canoa Ranch Road (Exit 56) will be reduced to 55 mph.

The widened segment will match with an adjacent segment of the frontage road that was widened in an earlier ADOT project and will provide room for bicyclists to use the shoulder. Additional work will include drainage improvements and replacement of guardrail.

ADOT advises drivers to proceed through the work zone with caution, slow down, and be alert for construction equipment and personnel.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule. To stay up-to-date with the latest highway conditions around the state, visit the ADOT Traveler Information Center or call 511.

For more information about this project, please call C.T. Revere, ADOT Senior Community Relations Officer, at 1.520.705.3574 or email at
