EDMONTON – If you live in parts of south and southeast Edmonton and have been hearing loud ‘boom’ sounds frequently throughout the day, don’t be alarmed.
EPCOR is advising south Edmonton residents, and those who live in southwest Strathcona County, that they may hear what sounds like a shotgun or small explosion as work on the Heartland Transmission Project continues.
According to project’s website, workers have been using implosive connectors to fuse portions of transmission line wire together since the beginning of October, which create a flash and sound like a small explosion. The blasts can be heard up to five kilometres away.
“As a warning before these connections, three horn blasts will occur. We expect an average of three large boom sounds to be produced per day, during typical working hours only,” the website reads.
Those living along the Heartland Transmission Line can expect to hear these booms throughout December as construction continues.
Crews have also been using helicopters during construction, to string power lines between towers and install equipment at the top of each tower.
