PORTLAND, Maine (NEWS CENTER) -- Contractors will be working around the clock for the next month, dredging the shipping channel in Portland Harbor for the first time in more than a dozen years.
To clear out sand and silt that have built up over the years and restore a minimum 35 foot clearance at mean low tide, crews will be using two massive dredges capable of scooping up three dump trucks worth of sediment at a time.
Norman Bourque, project manager for Cashman Dredging estimates they will remove nearly 500,000 cubic yards of material from the channel. He says they will also be blasting ledge in five different spots as part of the project.
Motorists are advised that the work will require the Casco Bay Bridge to open a few additional times daily during the next couple of weeks.
Work on the $9 million project is expected to be finished by March 15th.
