The City of Mesa has begun construction on a new natural gas pipeline near the Ironwood and Gantzel Road area, which may impact travel for San Tan Valley residents.

The project, being completed by Achen-Gardner Construction, includes work in two main areas:

• Along Pima Road, from Meridian Road to Ironwood Road
• Along Ironwood/Gantzel Road, from Pima Road south to Combs Road

Construction began during overnight hours and is taking place at night only to help reduce daytime traffic impacts.

Work along Ironwood/Gantzel Road is scheduled:

• Sunday through Friday nights
• 7:00 p.m. to 5:00 a.m.

Crews are boring a tunnel under Ironwood/Gantzel Road to install the natural gas pipeline. Traffic control devices are removed during daytime hours so the road can return to normal travel conditions.

Ironwood/Gantzel Road remains open to traffic during construction. However, drivers should expect:

• Lane restrictions
• Possible turn restrictions
• Shifts in traffic patterns near work zones

Business and residential access will continue to be maintained.

The project is expected to be completed in mid-2026.
