Morgan’s Wharf Bulkhead Rehabilitation

Location:
Curtis Bay (Baltimore), MD
Completed:
2007

Cianbro reconstructed the bulkhead at Morgan’s Wharf, adjacent to the U.S. Coast Guard Yard in Curtis Bay, MD.

Scope of Work

Cianbro dredged 28,000 cubic yards of material to achieve a 14 foot water depth, replaced the 250 linear feet sheet pile bulkhead, and installed timber dolphins, a relieving platform and a 2 foot by 3 foot duct bank. The project utilized the design/build project delivery method to control cost and deliver the project ahead of schedule.
