New I-10 signs to tell Tucson-Phoenix trucks to move right
Trucks on the remaining 20 miles of two-lane interstate corridor between Tucson and Phoenix will have to move over and stay there, as the Arizona Department of Transportation installs "Trucks Right Lane Only" signs between Casa Grande and Loop 202 this week.
"This segment has safety concerns due to heavy traffic flow and truck traffic," ADOT officials said. "The right-lane restriction for heavy vehicle truck traffic is intended to help reduce crashes, along with the resulting delays and closures due to these incidents."
In that stretch, heavy vehicles were involved in about 20 percent of all crashes, and 15 percent of rear-end and sideswipe crashes, officials said in a news release.
Crews began installing the signs Monday.
From the state agency:
The signs are intended to be in place until an improvement project kicks off to widen this segment of I-10. The first step is expected in 2023 with the replacement of bridges that carry traffic over the Gila River, following required environmental review and clearance. Also, ADOT is working closely with the Gila River Indian Community and the Maricopa Association of Governments to secure federal funding, to add to committed state funding, for work that could be completed as early as 2026.
The signs restricting heavy vehicle truck traffic to the right lane only are similar to those that ADOT has employed elsewhere, including I-17 north of Black Canyon City. Sign installation began Monday and is expected to continue through this week.
