A manhole explosion near Park and Prospect on Milwaukee's east side Tuesday evening cut electricity to roughly 4,500 people across Milwaukee and neighboring Shorewood, launching a manhole cover into the air and igniting equipment below the street. Fire crews rushed in as residents reported seeing flames shoot from the pavement while utility workers moved to restore service.
According to WISN, We Energies said an underground cable failed around 5 p.m. Crews repaired the fault and had power back on in about an hour. The Milwaukee Fire Department initially secured the scene, then turned the investigation over to the Milwaukee Police Department and the city's Department of Public Works.
Dispatch audio from the response reports "Engine 47 at Park and Murray" and notes that the manhole cover "blew off the ground," leaving power out for about two blocks along Park. Neighbors described flames shooting several feet from the pavement and said the blast rattled them. "I'm still shaken," Fitzgerald Scott told WISN.
What typically causes manhole blasts
Utility experts say fires and explosions like this usually trace back to electrical faults in aging underground cables, water getting into the system, or insulation breaking down, which can cause arcing and pressure to build beneath the street. Similar underground fires in other cities have damaged fiber and electrical networks and sent smoke, flames and manhole covers into the roadway, as WCVB reported.
Milwaukee's outage response and local context
Milwaukee has dealt with underground electrical blasts before, including a downtown manhole explosion years ago that required days of work by repair crews, according to local TV archives. The parent company that owns the utility has been touting investments aimed at improving reliability and shortening outage times in recent regulatory filings, WEC Energy Group noted.
What residents should do
If you see smoke or flames coming from a manhole or suddenly lose power, officials say to call 911 to report the hazard, then contact We Energies on its outage line. The utility's online outage map lists emergency contact numbers and safety tips and advises people to stay clear of downed wires and manhole covers while crews repair underground equipment, according to We Energies.
