The
Bridges
Covered bridges
found their way into Europe, during the
Middle Ages, from travelers who had seen
highly ornate, covered structures in the far
East. Some of these structures from the 1400
s can still be found in Europe.
The first covered
bridge in the United States appeared around
1805. This bridge, was called the Permanent
Bridge; located on Market Street, it crossed
the Schuylkill River in Philadelphia.
Timothy Palmer, a bridge builder from New
England, was hired to erect the lengthy
structure. Judge Richard Peters, chairman of
the bridge committee insisted that it be
covered to protect the two essential
features: trusses, which support the entire
structure and the deck or floor that carries
the live load. His insistence paid off,
because covering the bridge extended its
life. Unfortunately, the bridge was
destroyed by fire in 1875.
There have been at
least twenty different truss systems used by
covered bridge builders across the United
States. The one truss system that was used
in twelve of the remaining Bucks County
Bridges was common in the northeastern
states. The Town’s Lattice Truss was created
and patented by an American architect,
Ithiel Town from New England. An exception
is the unusual Boxed Pony Truss Bridge, in
Ralph Stover State Park, it was built using
the Howe Truss design.
At one time, over
fifty of these covered bridges stood in
Bucks County, many of them spanning the
Delaware River crossing into New Jersey.
Bucks County can boast thirteen of these
lovely, authentic, historic spans still in
existence today. Ten of the covered bridges
still carry vehicles.
