PORTSMOUTH, N.H. — The U.S. Army Corps of Engineers will start dredging the Piscataqua River in Maine and New Hampshire next month to remove about 15,000 cubic yards of sand and gravel.

The work will be done at a 35-foot-deep channel upstream from the Interstate 95 bridge in the Piscataqua and at Portsmouth Harbor.

The $878,000 project is being managed by the corps and will be done by Cashman Dredging & Marine Contracting Co. of Quincy, Mass. It will take several weeks to complete.
