The Hayes Clark Covered Bridge is one of the twin bridges located on the property of the Brandywine Conservancy near Coatesville, Pennsylvania.  The bridge is 86 feet in length and 17.4 feet wide.

Hayes Clark Bridge was built in 1871 and was constructed with a Queen truss variant, and it crosses Doe Run Creek on a private road within the Conservancy.  Open to pedestrians only.  Its twin bridge is the Speakman Bridge #2.

In older wooden covered bridges, the truss was structured using many smaller parts of wooden timbers.  The "King Post" truss is the simplest type, with a simple, wooden truss forming the center, and panels are added symmetrically.  One of the more common methods used for achieving longer spans was the "Multiple Kingpost Truss.

Length of largest span:  74.2 feet
Total length:  85.8 feet
Deck width:  17.4 feet

Of the 1,500 covered bridges that once stood in the state of Pennsylvania, as of 2019, approximately 200 remain.
