State Route 77 from Tangerine Road to Pinal County Line

Traffic Alert

SR 77 Construction North of Tucson July 2-12

Motorists traveling on SR 77 (Oracle Road), north of Oro Valley to Catalina, should be aware of the following traffic restrictions as the Arizona Department of Transportation has detoured traffic onto northbound SR 77 through summer 2015. The work is part of a project to widen the roadway between Tangerine Road and the Pinal County line.

Construction crews will not be working Thursday, July 2 through Sunday, July 5 in observance of the Independence Day holiday.

Construction Activities
  • Northbound SR 77 will be reduced to one lane overnight Monday, July 6 through Thursday, July 9 from 8 p.m. to 5 a.m. from Pinto Lane to Eagle Crest Ranch Boulevard for paving.
  • Grading work will continue at the driveways along SR 77 between Golder Ranch Drive and Eagle Crest Ranch Boulevard. Driveways on SR 77 will be closed but business access will be maintained at adjacent streets and driveways.

Law enforcement will be monitoring this area as the speed limit has been reduced as follows:

  • 40 mph from Tangerine Road to Rancho Vistoso Boulevard
  • 35 mph from Rancho Vistoso Boulevard to Eagle Crest Ranch Boulevard

SR 77 traffic has been shifted to the northbound side of SR 77 between Wilds Road and Vistoso Commerce Loop through summer 2015 to allow crews to construct the west side of the new wildlife overpass and underpass and widen the southbound side of SR 77. Two lanes of traffic will be maintained in each direction.

  • North- and southbound SR 77 traffic will be unable to turn left between Wilds Road and Vistoso Commerce Loop during this work.

The lane reduction on SR 77 has been extended to Tangerine Road through summer 2015.

The north- and southbound SR 77 shoulders between Tangerine Road and Eagle Crest Ranch Boulevard are closed through the remainder of the project.

The following right-turn bays will remain closed through 2015:

  • Southbound SR 77 between Vistoso Commerce Loop and Tangerine Road
  • Southbound SR 77 at Thistle Road
  • Northbound SR 77 at Golder Ranch Drive

Additionally, intermittent driveway closures will continue along SR 77, north of Tangerine Road, from 7 a.m. to 4 p.m. weekdays through summer 2015 for installing curb, concrete driveways, grading and paving. Driveway access will be maintained.

Drivers, cyclists and pedestrian are urged to obey traffic control, stay away from where crews are working and be cautious while traveling through the work zone, especially in the detour area as shoulders will be significantly restricted.

In addition, please be aware of the following traffic control:

  • Two lanes of travel in each direction will remain open through the work zone during the day.
  • Additional lane restrictions may happen throughout the work boundaries as needed.
  • Cyclists will need to merge safely into the traffic lane during shoulder closures.

ADOT works to inform the public about planned roadway restrictions, but there is a possibility that unscheduled closures or restrictions may occur due to weather or equipment issues.

Drivers are reminded to share the road, be cautious, and slow down while traveling through the work zone.
