Provided below is the most current construction information for the project.  As a reminder, the project has been divided into three phases so that more than one contractor will be working to better accommodate the expedited schedule for this project, which has a goal for completion in December 2012.

  • The Southwest Gas Pipeline Replacement Project is nearing completion. The main pipeline has been installed for Phases 1, 2 and 3; which includes pipeline from 75th Avenue north of Northern to I-17 at Northern. Cleaning and testing of the line is complete; however, work remains along the pipeline alignment to install pipe where connections need to take place. Before the main pipeline for all phases can be put into service, crews will purge and fill the line. This process is scheduled to take place during daytime hours, for approximately 1-2 days beginning Saturday, November 17th. As part of this activity, there will be a short period of loud noise, and there may also be noticeable odor or dust for those who live or work in the areas near I-17 and Northern; 59th Avenue and Northern; and 75th Avenue and Northern. This is all part of the standard process for putting the line into service. Safety personnel will be on-site for this activity, and emergency services will be notified.
  • Once the purge and fill operation is complete for the recently installed main pipeline, the next 2-3 weeks crews will conduct abandonments of the former line that will be coming out of service. This abandonment process can sometimes be conducted in existing manholes; however, there are some abandonment locations that will need excavation. This work typically takes 2-3 days to complete each abandonment, and there may be intermittent lane closures or traffic restrictions near the work zone.
  • Crews will also be conducting pavement restoration for asphalt and concrete in the project area. The work area will be picked up prior to the Thanksgiving holiday weekend; however, work will commence once again on Monday, November 26th, until the project is complete. On behalf of the project team, we wish you and your family a very Happy Thanksgiving!
