Energy Dynamics, Ltd. (EnDyn), played a major role in the construction of the longest Cable-Stay Span Bridge in North America. The new Cooper River Bridge was built to replace the existing truss bridges connecting the city of Charleston, South Carolina to the town of Mount Pleasant, South Carolina along US Highway 17.

EnDyn Manufacturing produced a critical component to the project — 256 anchorage assemblies that secured the 128 individual cables between the support piers of the bridge. Steve Hanks, General Manager for EnDyn Manufacturing, explains, “The anchorages are designed to secure the 128 cable assemblies to the deck and support piers. These cables will be anchored on the deck level and inside of the diamond towers. The assemblies are designed to hold over one million pounds or 500 tons each.”

Hanks adds, “The fact that EnDyn Manufacturing won the contract for this project is a testament to the quality of the machinists and processes we have in place.” The contract was worth approximately $1 million.

The total bridge project, worth $600 million, is the largest single infrastructure project in South Carolina history. The Cable-Stayed Span Bridge will hang from two diamond towers at each end of the 1,546-foot span. A signature icon for the Charleston region, the bridge is designed for a 100-year lifespan, and features the latest in seismic considerations with eight lanes of vehicular traffic and a shared pedestrian/bicycle lane overlooking the Charleston harbor.
