Dredging to begin in Portland Harbor
PORTLAND (WGME) -- Dredging begins Friday afternoon in the Portland Harbor.
The $9 million project will remove up to 500,000 cubic yards of sediment from the harbor.
A series of explosives will be set off around 4 p.m. The blasts will occur about 35 feet underwater, meaning the public will not hear or see much.
It will take about eight days to clear several ledges out of the shipping channel. It's the first such work in the harbor in about 15 years.
