I-10: SR85 to Verrado Way Improvements

I-10: SR85 to Verrado Way Improvements


This project is now complete - July 2023.


The Arizona Department of Transportation is making improvements to Interstate 10 between State Route 85 and Verrado Way in the City of Buckeye. The improvements include adding a third general purpose lane in each direction on I-10 and reconstructing the interchanges at Miller Road and Watson Road. These improvements will increase freeway capacity, improve traffic flow and safety at the interchanges and accommodate future growth in the city of Buckeye.

What to Expect

  • Construction will require periodic restrictions on I-10, interchange ramps and the cross streets at Miller and Watson roads.
  • The interchange ramps and cross streets at Miller and Watson roads will each be closed for several weeks for reconstruction. Only one interchange will be closed at a time to minimize impacts to drivers and businesses.
  • Restrictions and closures will be minimized to the extent possible to minimize impacts.
  • ADOT will share information about specific lane restrictions or closures as it becomes available and will provide advance notice of restrictions and closures.
