SRP - Pinal West to Pinal Central 500kV Transmission Project - Construction only
Constructed 14.1 miles of single circuit 500kV and 37.3 miles of double circuit 500/230kV electric transmission line on self-supporting galvanized steel pole structures from Pinal West Substation (near Mobile, AZ) to the new Duke Substation (SE of Maricopa AZ and adjacent to the existing Santa Rosa substation) then to the new Pinal Central Substation (807 South Eleven Corner Mile Road). The scope also included an additional 3.0 miles from the PCL substation east, to link to the existing 500/230kV transmission line. The transmission line crossed private property and State of Arizona Lands. Approximately 3 miles of the line route paralleled existing 115/230kV transmission lines. Line crossings included 230kV, 115kV, 69kV, distribution lines, Federal and State highways, Union Pacific RR, El Paso Natural Gas pipelines and irrigation canals.
