On the Move Partners in Progress logoUnder Proposition 400 in 2004, Maricopa County voters approved an extension of the half-cent sales tax for transportation. This series highlights projects built under Prop 400 — to let you know where your money is going and how it is improving your transportation experience.

The Valley has experienced continued growth over the past few decades and shows no signs of slowing down anytime soon. That is why projects like the widening of I-10 through Buckeye in the West Valley are critical to the region’s shared success.

The I-10 project in Buckeye is part of the Maricopa Association of Governments’ Regional Transportation Plan. It is funded in part by Prop 400, a half-cent sales tax for transportation improvements approved by Maricopa County voters in 2004. The funding is set to expire in 2025, unless voters are given the opportunity to vote on an extension of the sales tax.

Big Improvements Include Widening, Interchanges

The I-10 widening project added one lane in each direction of I-10 between State Route 85 and Verrado Way. To accommodate the extra lanes of traffic, the Arizona Department of Transportation (ADOT) rebuilt interchanges at Watson and Miller roads, and reconstructed ramps connecting I-10 to SR 85.

Mayor Eric Orsborn“What an incredible difference that makes in commuting,” said Buckeye Mayor Eric Orsborn, chair of the Maricopa Association of Governments (MAG) Transportation Policy Committee. “Not being stopped on the freeway coming home from a long commute, whether it is Phoenix or wherever, for our residents – I’m absolutely thrilled,” Orsborn added.

The project includes sound walls, drainage, new signs and stripping, a freeway management system, and new lighting. 

  • Helps accommodate future growth in Buckeye and the Southwest Valley.
  • Improves traffic flow along I-10 from SR 85 to Verrado Way.
  • Adds one general-purpose lane in each direction.
  • Rebuilds interchanges at Watson and Miller roads.

Meeting Future Growth

The $82 million project is designed to improve the area's safety and overall traffic flow. The changes will also be able to accommodate growth in the city of Buckeye. 

Work on the two-year project began in July 2021 and will be completed this summer.
