Underground construction begins for Western Milwaukee County Project

Western Milwaukee County underground construction

Construction is underway on the underground portion of our Western Milwaukee County Electric Reliability Project. The project involves construction of two sets of 138-kilovolt lines, each two miles long, to connect a new We Energies substation to the transmission grid. The two separate lines are needed to assure redundancy to the Milwaukee Regional Medical Center, which operates two Level 1 trauma centers. Although construction was not scheduled to start until next year, we took advantage of the opportunity to begin the underground portion ─about 1,250 feet─to coincide with underground road work being performed by the Wisconsin Department of Transportation.

Special foundations used for Wisconsin River island construction

We are using micropile technology to replace an aging transmission structure on an island in the Wisconsin River in Stevens Point, Wis.

A micropile is a high-performance drilled and grouted foundation that can be installed in environmentally sensitive locations using lightweight specialty equipment. In this case, the micropile will eliminate the need for bringing concrete trucks on to the island.

Seawalls have been installed along the shore in Bukolt Park in Stevens Point to accommodate a barge that will be used to ferry crews and equipment to the island when the work is performed this winter.
