There are several types of bridge protection systems used: [7] Pile-supported fender system on the James P. Houlihan Memorial Bridge. Fender systems attached to the pier with the goal to absorb the vessel impact. Their ability to withstand a typical ship collision is low. Fenders are built using a variety of materials: [8] thin-walled concrete box;
In 1987, another cargo ship struck the bridge, resulting in several million dollars of damages, but no injuries or fatalities.

The jaw-dropping collapse of Baltimore’s well-trafficked Francis Scott Key Bridge resulted after a rare set of circumstances — but still highlights how shipping and structural changes could ...
