Gantzel Road High Pressure Gas Line

Project Owner: City of Mesa
Project Type: Construction Manager at Risk
Construction Dates: 10/25 to 5/26

This project expanded natural gas infrastructure to support future industrial growth in the Queen Creek area, including the new LG Energy Solution battery manufacturing facility and other planned private developments.

Work included installing 22,000 LF of a new 12” high-pressure steel gas line along two major roadways:

  • Pima Road (from Meridian Road to Gantzel Road)

  • Gantzel Road (from Pima Road to Combs Road)

The pipeline was constructed within the rights-of-way maintained by both the Town of Queen Creek and Pinal County, which required close coordination and permitting. We worked collaboratively with both agencies to prioritize safety and minimize traffic disruption.

This is a high-traffic corridor serving local businesses, churches, schools, residents, and future developments. We actively coordinated with these stakeholders to maintain access throughout construction.

The pipeline also crossed an active Queen Creek Irrigation and Drainage District (QCIDD) ditch that supports farming in the area. To ensure uninterrupted access and irrigation service during construction, we coordinated closely with QCIDD, New Magma Irrigation and Drainage District, and the U.S. Bureau of Reclamation. To minimize impacts at irrigation crossings and reduce disruption within the roadway, we used directional drilling in several key areas:

  • Installed the gas pipeline beneath two irrigation crossings:

    • Pima Road at Meridian Road

    • Pima Road at Ironwood Road

  • Installed the gas line within Gantzel Road (from Pima Road to Combs Road) to reduce traffic impacts and limit restoration needs

In total, the project included more than 15,800 LF of directionally drilled 12” gas line, and this work was performed at night to further reduce impacts to traffic.

Additional project components included 12 valves (8” to 12”), three spherical tees, and four 8” to 12” tees. The project ties into existing gas lines, including one connection that was hot-tapped to prevent disruption to existing service.
