Great Lakes Dredge & Dock Corporation (“Great Lakes”) (NASDAQ:GLDD), the largest provider of dredging services in the United States and a major provider of environmental and remediation services, announced the receipt of two dredging contracts with a combined value of $39.6 million to deepen the main channel of the Delaware River in Philadelphia, Pennsylvania. Great Lakes will use a combination of hopper and clamshell vessels to dredge over one million cubic yards to deepen a section of the river from 40 feet to 45 feet. Great Lakes deepened a different section of the Delaware River two years ago and is looking forward to continuing its efforts to deepen the river’s navigation channel. Dredging is expected to begin this summer.

The U.S. Army Corps of Engineers Wilmington District recently awarded a $19.9 million contract to GLDD to provide dredging services to protect Highway 12, the only north-south highway along North Carolina’s Outer Banks. This coastal protection project involves placing approximately 1.7 million cubic yards of beachfill material immediately north of the Mirlo Beach community in Rodanthe, NC. This stretch of beach suffered severe beach erosion, dune loss and damage as a result of Super Storm Sandy in 2012. Great Lakes' cutter suction dredge Illinois is presently preparing to mobilize to the site to provide this much needed coastal protection. Mirlo Beach is one of many communities along the East Coast that need to rebuild and restore in the aftermath of Super Storm Sandy. Great Lakes has already completed four major Sandy coastal protection projects within the past 12 months.
