The opening of the Casco Bay Bridge over the Fore River will allow larger ships
The opening of the Casco Bay Bridge over the Fore River will allow larger ships to pass under the bridge, but extensive dredging must be done. Bottom sediments from Portland Harbor contain polycyclic aromatic hydrocarbons, which are toxic to marine life. An estimated million cubic yards needs to be dredged, and port backers say the investment would be worth it. Study of the results of last summer's dredging of the Royal River in Yarmouth indicate it might be possible to dispose of contaminated sediment at an offshore disposal site and cap it with a different material. Details.
