February 19, 2013 (Santee)--Motorists will have to be cautious along Magnolia Avenue and Mast Boulevard for the next several months because of a major construction project by San Diego Gas & Electric. Crews will be replacing wood and steel poles with galvanized steel and concrete poles.

The project footprint will span 11 miles from the utility’s Sycamore substation to the Santee substation near Mast Boulevard and Magnolia Avenue.  According to the City of Santee’s website, the infrastructure upgrades are necessary to service the expansion of the Las Colinas Women’s Detention Facility and to improve power circuit stability.
