CONSTRUCTION ALERT - JUNEAUTOWN SUBSTATION
The new “Juneautown Substation” (300 block of North Jefferson) will improve the efficiency and reliability of electrical service to power customers east of the Milwaukee River. To support the effort, ATC received Public Service Commission approval to construct a 138-kilovolt underground transmission line to connect to the new substation.
Constructed in two phases, the underground transmission lines will be located under Buffalo and Chicago streets with a portion traveling under the Milwaukee River. Construction on Phase 1 is already underway with Phase 2 scheduled to begin in late fall/early winter. The substation is anticipated to be online by September 2020.
ATC will continue to work with the City of Milwaukee and Historic Third Ward Association on project management and communication regarding disruption of traffic as well as access to private property and parking, particularly during special events in the area. Similar to our efforts during the Milwaukee Streetcar and freeway deck construction projects, we are meeting weekly with ATC’s team and will share information with you as construction progresses.
The first phase of construction is taking place in the 200 and 300 blocks of N. Jefferson and the 400 blocks of E. Chicago and E. Buffalo. A trench for the new transmission line will be created in the roadways. Traffic will be restricted in at least one direction and parking will be limited throughout the construction zone. The construction will start first on Jefferson south to Buffalo, turning the corner west on Buffalo to the alley; then continuing south on Jefferson and turning the corner west onto Chicago to the mid-block. Some work on will also occur on Plankinton on the west side of the river during this phase. Phase 1 is scheduled to run from mid-July to October 2019.
Phase 2 construction will work westward toward and under the Milwaukee River on Chicago and Buffalo streets. This phase will include boring underground for the installations of the transmission lines. Please be aware no parking zones, one-way traffic patterns, and construction of the drop shafts in certain areas will still be present as construction proceeds. The timing, sequencing, parking, and traffic patterns for this phase are still being determined. Phase 2 is scheduled to start in Fall 2019 with completion scheduled for Summer 2020.
