ADOT to begin improvements on Interstate 8 near Casa Grande

Motorists should plan ahead, expect possible delays for paving work

PHOENIX ‒ The Arizona Department of Transportation will begin resurfacing approximately nine miles of Interstate 8 near Casa Grande on Monday, Oct. 26.

The $7.3 million improvement project in Pinal County will extend from Bianco Road to the Interstate 10 junction (mileposts 170-179) and will include pavement treatments at Santa Cruz Bridge, Thornton Road, Trekell Road, Peart Road and the I-8/I-10 ramp.

On Oct. 26, I-8 will be reduced to one lane in each direction at Peart Road (mileposts 175-176) in Casa Grande from 7 a.m. to 3:30 p.m.

Lane restrictions will be in effect for the duration of the project as well as a 55 mph speed limit through the work zone. Those traveling through the area are reminded to share the road, be cautious and slow down.

In addition to removing and replacing pavement, the project will include new box culvert pipe extensions, pavement markings, cattle guards and lowering Thornton Road to meet the new bridge height of 16 feet.

The project is expected to be completed in summer 2016.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur.
