The Dredge Rockbridge and Lexington performed Maintenance and New-Work Dredging in Norfolk Harbor and Craney island Reaches.  Norfolk International Terminals Access Channels and Berthing Areas, were also dredged.  

The work in Norfolk Harbor and Craney Island Reach consisted of maintenance dredging to a required depth of 52 feet MLLW with one foot of allowable overdepth. The dredging involved approximately 875,000 cubic yards of material, including allowable overdepth.  The work in Norfolk International Terminals Access Channels and Berthing Areas consisted of maintenance and new-work dredging to a required depth of 51 feet MLLW with one foot of allowable overdepth. The dredging involved approximately 460,000 cubic yards of material, including allowable overdepth The material was transported by submerged pipeline and placed in the designated Government-furnished placement area at Craney Island.  One of the largest challenges for this project was the volume of military, commercial and recreational vessel traffic located in the channel.  Cottrell executed the project without damage to any vessel and without impacting shipping or military activities.  

Dredging was conducted seven days a week, 24 hours a day without a loss time accident.
